What the hell is an eSIM? Just the next important phone feature you need to know



  SIM Cards

Plastic SIM cards are soon history.

The iPhone 1

1 Pixel 4 and the new foldable Motorola Razr all have something in common, and no, not only are all the phones. They all can store your phone number – the essential ingredient for making calls and sending texts – in a so-called eSIM . An eSIM not only makes it easier and faster to set up a service with your mobile service provider, but also allows you to have two phone numbers on one phone.

An eSIM is not nearly as exciting as a foldable screen or a camera that can take pictures in the dark, but an important part of our phones. Without a SIM card our phones can not connect to our mobile service providers and may also be a iPod . In addition to the technological advances in the displays, the SIM card is also changing – and for the better.

What exactly is an eSIM and why should it interest you? Nice that you asked. Here you will find everything you need to know about eSIM technology and why it matters.

What is an eSIM?

An eSIM (Embedded Subscriber Identity Module) is a small electronic chip in a phone that has the same function as the small plastic SIM cards we have been using for years. Without a SIM card, your phone does not know which network operator or phone number to connect to, and your network operator does not know which phone to serve.

What are the advantages of an eSIM?

Unlike mobile-enabled SIM cards, which prevent switching between mobile operators, an eSIM can be programmed and reprogrammed as needed so you can switch between mobile service providers or cancel and start the service each time you need a new SIM card to get.

Without a removable SIM card slot and the space required for it, phone manufacturers can accommodate larger batteries in the case of a phone or use the extra space for additional cameras or new features. Of course, no SIM card slot probably means there is no microSD card slot for extra storage.

The eSIM is still young and as such the process for things like activation and support mobile operators and phone manufacturers need to be optimized (more on these two aspects below), but one thing is clear: one day we'll be able to just a few taps on the display of our phone immediately switch between mobile operators.

One thing you will not find on the new Razr is a SIM card slot. Juan Garzon / CNET

Which phones are currently using an eSIM?

Not many phones currently use eSIM.

Apple's iPhone XS, XS Max, XR, 11, 11 Pro, and 11 Pro Max All have an eSIM in addition to the standard plastic SIM card (more on that below).

Google's Pixels 2, 3, 3A and 4 also have a standard SIM card slot and eSIM support.

Samsung's Galaxy Fold has an eSIM and a micro SIM card slot.

The Motorola Razr is the first phone to come onto the market without a physical SIM card slot on eSIM.

When you free up the space that a SIM slot occupies, phone manufacturers can do many things.

Why an eSIM and a physical SIM card?

Apple's iPhone with two SIM cards – an eSIM and a physical card – can be connected simultaneously with two different mobile operators and phone numbers time. So you can have your personal and business number on an iPhone, even if you have T-Mobile or Verizon Wireless as a provider. This is possible on an iPhone because it is unlocked and supports multiple carriers.

eSIM phones are also suitable for frequent travelers outside the country. With the eSIM, you can sign up for a data plan abroad and save roaming charges. And if you set up an eSIM through a provider like GigSky before you leave, you will have access to your data immediately after landing.

Of course, you do not have to use both SIM cards at the same time. When you buy the phone from your network operator, there is usually already a standard SIM card installed that you can use to connect to your account.

However, if you buy a phone without a SIM card, such as from select merchants or websites like Swappa, you need to visit your mobile service provider or order a SIM card and wait for their arrival in the mail, then it will be activated. With an eSIM you do not have to wait – you can activate the phone in just a few minutes.

Did you know that you can link two phone numbers to your iPhone?

Will all phones start using eSIM cards?

Yes. For phone manufacturers and network operators, it makes sense to throw away the plastic SIM cards, both for cost and environmental reasons, considering the large plastic card that comes with a standard SIM card.

Does my mobile service provider need to support eSIM technology so I can use it?

Yes. Apple has a list of all mobile carriers around the world that support the iPhone's eSIM feature.

Google's pixel is a bit confusing. Google Fi Google's prepaid mobile service provider, can use an eSIM. Some US vendors, such as AT & T and Sprint, support eSIM for Pixel 4, but not for older Pixel phones.

Now, when I try to add an eSIM mobile plan to my Pixel 4 XL, I can choose between AT & T, Sprint and Google Fi.

It seems like a hit or miss when it comes to which network operator supports which device, and it gets even more confusing when you're dealing with dual-SIM support.

If you have a Pixel phone and want to use its eSIM functionality, contact your wireless service provider to inquire about eSIM support for your particular model.

Setting up the iPhone's eSIM feature takes only a few minutes.

Phones are not the only devices that use eSIM.

The eSIM technology is not only found in telephones. The Apple Watch (19459014) and the Samsung Galaxy Watch (19459005) with cellular connection connect to your mobile service provider via eSIM. Some of Apple's iPad models with mobile phones also have an eSIM. There are also some laptops presented, z. For example, Surface Pro has eSIM capabilities.

How do I set up an eSIM?

The process depends on your wireless service provider. AT & T users need an eSIM activation card from the network operator. On it is a QR code that you can use to program the eSIM with your information. Some network operators, such as Verizon Wireless, are programming the eSIM with their mobile app.

It is recommended that you check the eSIM activation process with your mobile service provider again.

Setting up an eSIM on your iPhone only takes a few seconds. If you want to see what life is like with an eSIM only phone, the Motorola Razr hinged with its innovative hinge is just the ticket for $ 1,500. You can order the Razr from the 26th of December . Shipping starts in January.
