Suggested April 2024 What Is Esim And Who Can Use It?

These days, physical SIM cards come in various forms designed to fit phones of all sizes. When you want to change networks, it’s as simple as taking the old SIM out and putting in a new one – that is, if your phone is unlocked! However, this is not the only way users can change networks, as eSIMs are beginning to gain traction. If you have been wondering what an eSIM is, you have landed in the right place. Here we will try to answer all queries you might have about eSIMs.

What Is an eSIM?

An eSIM or embedded SIM is just as its name suggests – a SIM card embedded within the device itself. An eSIM is basically an electronic and programmable form of a traditional SIM card on which you need to download a SIM profile from your carrier. It can also be called a virtual SIM as you can connect to your carrier network without a physical SIM card.

At the same time, you won’t find a eSIM card port on the phone, and you can’t physically take it out of the device. It’s buried within the phone’s processor and not removable. However, just like a swappable SIM card, you can change the eSIM to a different network (if it’s not locked that is). eSIMs are rewritable. That means you can change networks without removing your SIM. However, you will have to erase the existing eSIM profile and activate the new one.

eSIMs provide alternatives for phones that do not support a second SIM card. Most big manufacturers like Apple, Google, Samsung, etc., have incorporated eSIMs in some way or the other.

eSIM vs Physical SIM: What’s the Difference

While both eSIM and physical SIM provide the same functionality, they differ in a number of ways:

The physical SIM is removable. That’s not the case with eSIM as you cannot physically remove it.

One can easily switch phones in case of physical SIM cards. In contrast, you will need to contact your mobile carrier in most cases to change eSIM from one device to another.

SMS services might stop working for 24 hours as you transfer your eSIM to a new device. Nevertheless, this is a security measure that may not be applicable to all mobile carriers. Case in point, in our experience they did stop working while using the JIO network in India. You might be able to avoid this inconvenience by reading the instructions very carefully before switching your eSIM to a new device. Comparatively, this doesn’t happen when you switch a physical SIM card to a new device.

Traditional SIM cards can store contacts. This is not possible with eSIMs. But it shouldn’t matter much as most users store contacts in the cloud now.

Who Can Use eSIM?

At this point in time, eSIM isn’t available just to everyone. You’ll need to have a certain phone model and use a certain network to be able to give it a try. Today, it’s mostly flagships that offer eSIM capability including:

iPhone XS / XS Max or newer

iPhone SE (3rd Gen)

Google Pixel 3+

Samsung Galaxy S20 series +

In addition to mobile phones, smartwatches like Apple Watch Series 3 and above, Samsung Galaxy watches, and many computers also include eSIM technology. Apart from that, other IoT products like cars, smart meters, security systems, etc., can also support eSIM.

In the US, AT&T, T-Mobile USA, Verizon Wireless, Truphone, Ubigi, and Visible support eSIM.

A carrier’s both new and existing users can apply for eSIM. For existing users, their physical SIM card will become non-functional after activating eSIM.

How to Activate eSIM

The steps to activate eSIM differ slightly for each mobile operator and device. However, in most cases, the mobile operator will share a QR code consisting of the eSIM profile that you need to scan from your mobile.

Or, you will have to manually activate the profile by sharing your phone’s IMEI and IMSI numbers. Don’t worry. Your mobile operator will share a complete set of instructions when you apply for eSIM. Below you can see an example of a SMS sent by our mobile operator which includes the complete instructions on how to activate our eSIM.

Advantages of eSIM Cards

Moreover, eSIM cannot be damaged or lost unlike your physical SIM card unless you lose your phone. Also, eSIM is secure as it can’t be duplicated easily, provided you don’t share the QR code or other important information like IMSI or virtual SIM number with others.

Also, by removing the tray required for SIM cards, manufacturers can design their phones to be thinner. You don’t have to worry about the SIM change – just enjoy your sleeker device!

Further, in order to use eSIM, both the network provider and your smartphone should have support for the eSIM functionality otherwise it won’t work.

eSIM also makes it difficult to identify and fix network issues. Generally, one would remove the physical SIM card or put it in another phone to check if the problem is due to the network or on the phone. This isn’t easy to handle with eSIMs.

The move from a user-replaceable SIM to one fixed inside the device is causing some users to voice concerns about limitations, identifying this aspect as another part of the phone they can’t customize.

Frequently Asked Questions Can you convert from eSIM to physical SIM?

Yes, you can switch to a physical SIM card from an eSIM. However, you will need to contact and visit the mobile carrier store in order to do so.

How many eSIM profiles can you store on one device?

Some devices can only store one profile, so you’ll need to erase the old and download the new network profile to make the change. Other devices allow you to store multiple eSIM profiles. You can easily switch to one of them from the device’s settings on the fly.

Is it possible to receiving calls from both SIM cards on the same phone?

You can make and receive calls from both numbers on your phone. However, you can receive or make calls from only one number at a time. That is, if you are on a call from one number, you won’t receive calls to another number. Call waiting functionality only works for the calls for the same SIM card.

What Is Macbook ‘Thermal Throttling’ And What Can I Do About It?

You might have heard that the latest MacBooks are a hot item. Literally. The controversy surrounding CPU thermal throttling in recent MacBooks may have cooled down, but there are probably more than a few still asking what “thermal throttling” is in the first place. Is it a big deal? Does it even affect you? Surprisingly, the answer isn’t black and white. The (rather touchy) topic of MacBook thermal throttling requires a slightly deeper look at the inner workings of your laptop to fully understand.

Which MacBooks are affected?

In principle, any MacBook (or really any high-performance laptop) can be affected by thermal throttling under the “right” circumstances. However, some models have been particularly likely to exhibit a case of heatstroke.

Most recently, MacBooks Pro models from both 2023 and 2023 have shown severe throttling issues. In the case of the 2023 MacBook Pro 15-inch and 13-inch (with Touch Bar) models, a now-fixed firmware bug was the culprit. We ran a poll, asking our readers whether Apple should make a thicker MacBook to solve thermal issues in future models. The results were in favor of a chunkier MacBook with more thermal headroom. Unfortunately, the 2023 15-inch MacBook Pro showed that Apple still had to take aggressive measures to keep the temperatures down.

In this case, however, it wasn’t throttling, but a lowered voltage from the factory, which indicates that the core problem of limited thermal headroom is still stalking the MacBook Pro line. This may very well be one of the main reasons Apple is strongly moving towards using its own cool-running ARM processors instead.

What causes a MacBook to thermal throttle?

Energy in the form of electricity is the magic that makes a computer work, but the byproduct of doing work with that energy is heat. Some portion of the electricity your CPU uses to do all those calculations is wasted and heats everything up. This is a bad thing because there’s a temperature range within which the circuitry works properly and, of course, very high temperatures where the materials that make up the CPU itself could be damaged.

The manufacturer specifies a temperature range that should never be exceeded if you want your CPU to last for its full natural lifespan. The exact numbers vary from one CPU model to the next, but every CPU has a limit.

When you ask the CPU to do something that requires most or all of its processing power, heat starts building up rapidly. The cooling system of your MacBook kicks in to move that heat away from the CPU and out of your system. Usually, this cooling system involves a metal heatsink directly attached to the CPU package and a fan system that moves air over that it, so that the built-up energy can be transported into the room instead.

Current MacBook Pro status:

— ؜ (@levelsio) November 1, 2023

If the cooling system is doing its best, but the temperatures keep rising, throttling is next on the list of remedies to stall the road to heat death. When thermal throttling happens, the CPU slows down below its base clock speed to stop short of hitting the maximum temperature specified by the CPU maker. The result is a cooler CPU, but also one that’s slower than it’s meant to be.

How to mitigate MacBook thermal throttling

With the exception of throttling caused by a bug, there are a few things you can do to prevent your MacBook from getting so hot that it needs to give itself a temporary lobotomy to cope.

Give it space to breathe

There needs to be enough airflow around the machine to let it move air through the system. Which means making sure all air vents are clean and unobstructed. Heat also leaves the laptop through the body itself, so it can help to put your MacBook on a stand to optimize how much surface area gets good airflow.

Learn acceptance

In the end, however, thermal throttling may simply be the price one has to pay in exchange for an incredibly thin and light form factor or acceptable fan noise. While a throttled CPU may perform worse than it’s on-paper minimum levels, that lower performance level could still be perfectly adequate in practical day-to-day work. This means that throttling is only a problem when, well, it’s actually a  problem.

Upgrade or change laptops

Finally, your best bet might be to upgrade or change laptops. Our own Jeff Benjamin noted in his look at the 2023 MacBook Pro earlier this year that that particular model tended to keep from throttling a bit better than others:

Although throttling will always play a role in space-constrained laptops, I find that the CPU in the 2023 MacBook Pro stays at or above its base clock speed while under load. Of course, it won’t be able to turbo boost for extended periods of time, but that’s to be expected.

Samsung Galaxy Theme Store: What It Is And How To Use It

Joe Hindy / Android Authority

Samsung was one of the first OEMs to have a theme store. The company updated the store over the years and it helps one of the best experiences on any Android device. It even works with Android 13’s Material You theming in that Samsung doesn’t let the store affect Material You’s ability to operate. We’ll show you around the Samsung Galaxy Theme Store and show you how it works.

We wrote this article using a Samsung Galaxy S22 Ultra. Your experience may vary depending on which version of Android and One UI your Samsung phone runs.

Read more: Samsung S Pen: The ultimate guide

Before you start – Make sure that you are logged into a Samsung account. Your Samsung account remembers prior purchases. You also need it if you decide to acquire any themes from the theme store.

Easiest method – Long-press an empty spot on your home screen and tap the Themes option.

Through the menu – Enter into your phone’s Settings menu, scroll down, and tap the Themes option.

That’s really all there is to it. Samsung made it very easy to access the theme store. However, you do need a Samsung account for the Theme Store for the same reason you need a Google account for the Google Play Store. Those who refuse to use Samsung accounts may not be able to utilize the Theme Store fully.

How to browse the Samsung Galaxy Theme Store

Joe Hindy / Android Authority

General navigation in Samsung’s Theme Store is pretty simple.

Bottom navigation – The bottom of the screen houses the five primary categories in the Theme Store. They include Themes, Wallpapers, Icons, AODs, and Menu.

The Menu section lets you view things like Events, previously purchased items, receipts, and you can manage your payment methods there. It also houses your recently viewed stuff, wish list, and a second Settings menu. The second Settings menu lets you control things like auto-updates, notifications, and more.

The above tools should help you easily navigate through the Samsung Galaxy Theme Store. It’s not a complicated piece of software, so there isn’t all that much to it.

How to buy and apply stuff from the Samsung Galaxy Theme Store

Joe Hindy / Android Authority

Buying stuff is also fairly simple on the Theme Store. You’ll need a Samsung account and at least one payment method. Luckily, it can pull your payment method from Samsung Pay, so you can set it up there if you so choose. You’ll also need a billing address. Samsung will stop you and make you do all three of those things before you can buy anything.

Find the theme, wallpaper, icon pack, or AOD theme you want to buy.

Select your payment method. I usually just use Samsung Pay.

You’ll load into another screen where you can verify with the total, including taxes.

Once you own the item, you can tap the Apply button. The method after that may change based on what you bought, but it’s fairly straightforward from there.

Please note – Free items don’t require a payment process. You simply tap the Download button to get to the Apply button.

You can also apply wallpapers from the wallpaper picker outside of the Theme Store. The same applies to AOD themes.

That should do it. You now have all the tools necessary to view, browse, buy, and apply stuff from the Samsung Galaxy Theme Store.

Up next: Samsung Pay: What is it, how does it work, and how do I use it?

FAQ

It comes installed on any modern Samsung phone. You can read more about it here.

Updates should come automatically without any input from you. There is a setting in the Theme Store where you can control auto-updates for individual themes, icons, wallpapers, etc.

What Is Android Recovery Mode And How To Use It

What is Android recovery mode?

Android recovery mode is a unique startup mode available in all Android devices that provide a set of tools for diagnosing and resolving issues that cannot be addressed from within the operating system. This mode is typically used to perform system updates, factory resets, or install custom ROMs.

Commonly used for troubleshooting and maintenance, the recovery mode provides options like wiping data/factory reset, clearing cache partition, applying updates from ABD or SD cards, and more. In essence, recovery mode serves as a separate bootable partition that is essential for performing system-level tasks and making changes to the Android system’s file system.

How to boot your Android device into recovery mode

While most Android devices follow the process of holding the Power and Volume Down buttons to enter recovery mode, there are variations among manufacturers. We will cover the procedures for Samsung, Pixel, and Motorola smartphones.

Samsung Smartphones

Turn off your Samsung device.

Press and hold the Volume Up and the Power button simultaneously until the Samsung logo appears.

Release all buttons when the device vibrates once. The Android recovery mode menu should now appear.

Pixel Smartphones

Turn off your Pixel phone.

Once the screen goes black, press and hold the Power and Volume Down buttons together until you see the bootloader screen appear.

Use the Volume keys button to navigate to the Recovery Mode option and use the Power button to select it.

Motorola Smartphones

Power off your Motorola device.

Press and hold the Power and Volume Down buttons for a few seconds until the bootloader appears.

Use the Volume buttons to navigate to the Recovery option and select it using the Power button.

How to use Android recovery mode

Recovery mode offers several options for troubleshooting and device management. Let’s explore each function:

Reboot system now: This option allows you to exit the recovery mode without making any changes.

Apply update from ADB: This enables the installation of updates or custom ROMs via Android Debug Bridge (ADB) from your computer.

Wipe data/factory reset: This performs a factory reset, wiping all data and restoring your device to its original factory settings. It’s a handy feature when your device isn’t functioning correctly or before you give away or sell your device.

Wipe cache partition: This deletes temporary files that can be safely removed without losing any important data. It’s typically used to free up storage or troubleshoot problems caused by corrupted files.

Apply update from SD card: If you have an update file or a custom ROM on your SD card, you can use this option to install it.

How to exit recovery mode on Android

To exit recovery mode on Samsung, Google Pixel, or Motorola devices, navigate to the Reboot system now option using the Volume buttons for navigation and select it using the Power button.

FAQs

To exit recovery mode, use the volume buttons to navigate to the “Reboot system now” option, then press the power button to select it. Your phone will then reboot back into normal operation.

Rebooting to recovery mode refers to restarting your Android device into a special mode (Recovery Mode) designed for troubleshooting and system updates. It’s a separate partition in the device’s memory that contains a lightweight Android OS version different from the main operating system. You can perform tasks like factory resets, clearing cache, or updating software.

No, entering Android recovery mode itself does not erase everything. It’s a troubleshooting interface with various options, one of which is Factory Reset. If you select the Factory Reset option, then yes, all data will be erased. But simply entering recovery mode will not erase anything.

Turn off your Samsung device. Then press and hold the Power and Volume Up buttons simultaneously. For older models (S10, Note 10, and older), press and hold the Power, Volume Up, and Bixby/Home buttons simultaneously. Release all buttons when the Samsung logo appears. The recovery mode menu should now appear.

If your device’s power button is not functioning, you can use ADB (Android Debug Bridge) commands to boot into recovery mode. You’ll need a computer with ADB installed and a USB cable to connect your phone to the computer to do this. Once connected, open a command prompt or terminal window and type the command: “adb reboot recovery.” Your phone should reboot into recovery mode.

Note: You must enable USB debugging on your phone for this method to work.

What Is Bitmoji And How To Use It On Snapchat

Bitmoji is the brainchild of Bitstrips, a Canada-based startup that Snapchat acquired reportedly for $100 million last year. Earlier, you could use Bitmoji to create an adorable, cartoony version of your picture and send them to your friends in messenger apps like Facebook Messenger. But Snapchat, having acquired Bitmoji, is aiming at integrating it tightly into its ephemeral chat app. Now, you can send Bitmoji avatars to your contacts or add them as stickers to your regular snaps. Despite the fanfare that it has received, some people haven’t been able to board on the Bitmoji train. So, today I’ll tell you what actually is Bitmoji and how you can use Bitmoji on Snapchat. Let’s begin, shall we?

What is Bitmoji?

Bitmoji is an app available for Android, iOS and Chrome. At its core, the app lets you create a personal emoji/avatar and then share it across different apps. Sounds extremely simple, right?

Well, the real power of Bitmoji is the number of customization options available, so you can choose between lots of different styles and settle on the one you really like. This is the reason why Bitmoji can potentially closely resemble the real-life you. (Sometimes, even more adorable!) It’s a great way to jazz-up the vanilla look of the standard emojis. In the next section, I’ll tell you about how you can create a Bitmoji using the colossal amount of options.

How to Make a Bitmoji?

Creating a Bitmoji is dead simple. Upon opening the app, it’ll show you hundreds of ready-made Bitmojis and you can tap on any one of them to share to WhatsApp, Twitter, Instagram and other social networking services. If you are feeling artsy, you can customize your own avatar and the change will be reflected in all the Bitmojis with your new face and attire.

To make your own Bitmoji, tap on the “edit” option as shown below:

You’ll be presented with a Bitmoji style and a Bitstrips style. You can tap on the one you like.

From here on, there are hundreds of options to customize each and every face detail— hair style, eyebrows, nose, facial hear and a lot more. Oh, and it doesn’t just stop there. If you’re feeling fancy, you can even select from a wide range of glasses, headgear— you name it. After you’re done, you can just tap the right mark to continue.

As if that was not enough, you can even flaunt your avatar with custom dresses from brands like Forever21, Foot Locker, Steve Maden and more. To dress-up, just tap on the “T-shirt” icon, choose an outfit and you’re good to go.

At this point, you’ve successfully created your own personal Bitmoji avatar. Now, as you can see, all the Bitmojis in the app are updated to reflect the avatar you created.

Using Bitmoji on Different Platforms

Select Bitmoji. Tap on Bitmoji and tap “Allow full access“.

Next, just tap on the globe icon to switch to the Bitmoji keyboard.

Now you can directly share Bitmojis just by tapping on them from the keyboard. Super convenient, right?

Where You Can Use Bitmojis

Using the Bitmoji keyboard, you can share your avatars on WhatsApp, iMessages, Hangouts, etc. On Android, you can send a Bitmoji by just tapping one on the Bitmoji keyboard. If the app doesn’t support Bitmoji, it will show a message that Bitmoji is incompatible with the current app.

The Chrome extension adds a button to Chrome, from where you can copy and paste Bitmojis. It adds a special button to Gmail, so you can directly insert a Bitmoji to any mail.

Pro-tip: On both Android and iOS, you can save an image from the Bitmoji app to the gallery for later use. To do this, tap on the avatar and select “Save Image/Save“.

How to Use Bitmoji on Snapchat

Bitmoji, of course, is integrated very well into Snapchat. But first, you’ll need to connect your Snapchat account with Bitmoji.

To do this, open Snapchat, tap on the “ghost” icon and subsequently tap on “Create Bitmoji“.

Next, tap on “Create Bitmoji” one more time.

Confirm by tapping on “Agree and Connect“.

You’ve now successfully connected your Snapchat account with Bitmoji. To reply with Bitmoji, just tap on the “emoji” icon and select any of the Bitmojis.

To add Bitmojis as stickers to you regular snaps, just tap on the “paper” icon.

What Is Screen Burn In And How Can You Prevent It?

What is screen burn in?

Eric Zeman / Android Authority

The word “burn in” is a little misleading, as no actual burning or heat problems are involved. Instead, this term describes a display suffering from permanent discoloration across any part of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches and patterns on display. The display still works as expected, but a somewhat noticeable ghost image or discoloration persists when the screen is on. To be considered screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side. Rather than a graphical glitch that may be caused by software, temporary image retention, or a problem with the display driver circuitry.

The term dates back to old CRT monitors, where phosphor compounds that emit light to produce images lost their luminance with time. LCD panels can exhibit similar problems, but these are much rarer due to the nature of LCD’s backlight and color matrix design.

OLED displays are made up of red, green, and blue LEDs, but the different colors have different lifespans.

Speaking more technically, the issue is that blue LEDs have significantly lower luminous efficiency than red or green pixels. This means that a blue LED needs to be driven at a higher current for a set sized pixel to achieve the same brightness as red or green. Higher current causes the pixel to degrade faster, shortening its lifespan and eventually tinting the display towards the red and green colors. Therefore an OLED display’s color doesn’t degrade evenly; it will ultimately lean towards a red/green tint.

So, if one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas. That’s essentially what burn in is. However, display manufacturers do account for this in their panel designs.

Why do we use OLED screens if they have a burn in problem?

Robert Triggs / Android Authority

If OLED screens have a problem with burn in, why do we continue using them? Burn in is a true downside to OLED displays, but there are plenty of reasons consumers and manufacturers like them. For starters, image quality is much better than in LCDs. OLED panels can reproduce more vibrant colors, more contrast, wider viewing angles, and faster refresh rates. Colors tend to be much more saturated, and blacks are much darker.

OLED displays have a simpler design, allowing thinner, lighter smartphone designs. You can also thank OLED technology for foldable phones and curved displays. If those improvements weren’t enough, you’ll also enjoy lower power consumption with OLED.

Additionally, burn in problems are only common after prolonged periods of use. As you may already know, smartphone manufacturers don’t expect you to keep a smartphone for more than 2-3 years. Recent statistics show that consumers currently keep their phones for an average of 2.65 years.

Can you avoid it?

Ryan Haines / Android Authority

At this stage, manufacturers are very aware of the potential issues and have already taken some intelligent steps to help avoid burn in. For starters, Samsung has been using its pentile subpixel arrangement in its AMOLED displays since the Galaxy S3. By making the blue subpixel larger, it requires less current to drive in order to provide the necessary light. Driving the LED with less current increases its lifespan, so it takes longer for any noticeable color shift to occur.

This doesn’t directly address the issue of different parts of the screen aging at different rates, but it does mean that it will take significantly longer to notice than with older or cheaper OLED panels. More expensive and modern OLED panels are built with longer-lasting LEDs and well-designed layouts, meaning flagship smartphone displays age slower. These days, it’s cheaper phones packing cheaper displays that are marginally more likely to see issues after heavy use.

Display technology has improved, and most consumers can use their phones for years without any sign of burn in.

There are software solutions too. Android Wear product manufacturers can enable the OS’s “burn protection” option. This mode periodically shifts the screen’s contents by a few pixels, so they spend equal time displaying different colors. Smartphones equipped with Always-On display technology employ a similar tactic. Google also suggests a selection of design guidelines tailored to avoid screen burn-in problems when designing OLED watches. The move towards gesture rather than on-screen navigation controls is also helping to alleviate one of the more noticeable burn in areas.

But what can I do? Is there a fix?

Robert Triggs / Android Authority

If your screen is already burnt in, there’s not much that can be done to undo the damage. Some apps on the Play Store claim to reverse the problem. These will end up “burning” the rest of the screen to match the colors, which isn’t a real solution.

There are several preventative measures to prolong the display’s lifetime:

Keep your display brightness as low as reasonable. Increased brightness requires more current and therefore shortens LED lifespans. Don’t crank up the brightness unless you have to.

Shorten your screen-off timer. Turning the screen off when you’re not using it will prevent displaying static images.

Use Dark Mode, if supported. Using a darker interface reduces the amount of illumination and helps LEDs last longer.

Use Immersive Mode, where available. This hides the notification bar and its static icons. Alternatively, pick a launcher that offers a similar feature, as well as a transparent navigation bar and app drawer options.

Pick a wallpaper with darker colors and change it now and again.

Use keyboards that offer darker themes to prevent color degradation in the lower half of the display.

Do you use a navigation app regularly for long journeys? Pick one that doesn’t have a lot of bright static UI elements.

Switch to gesture navigation and drop the buttons, if your phone supports it. This helps to prevent burn in at the bottom of the screen.

Try to make it so that the screen isn’t displaying the same thing all the time, in the same areas of the screen. For example, if you have a widget that almost always looks the same, chances are it will eventually burn into the image. Move things around now and then, and try to keep the view of your phone dynamic.

FAQs

What is

Display burn in refers to the discoloration of lighting and colors across any part of a screen panel. As screens age, pixels can begin loosing brightness. When worn out pixels emit too much light for long periods, this can cause certain sections of the screen to look dimmer, or less colorful.

Screen burn in is inevitable. If you’re using a screen, it will eventually lose its brightness. That said, there are some things you can do to elongate a display’s lifespan. These include lowering the brightness, reducing the time a screen takes to go to sleep, avoiding always-on displays, and more.

Display burn in is permanent damage, so there is no way to fix it other than replacing the panel.

OLED technology is known for burning in more easily. QLED technology hasn’t made it to smartphones, but it is said to be much better at handling this issue. In fact, Samsung covers screen burn in warranty claims for up to 10 years on QLED panels.
