Samsung & # 39; sand join the En the new, foldable as the small handful of phones that uses a new . What that means depends on the telephone. For some, such as the Razr, you can completely throw away your plastic SIM card. For others, such as the iPhone 11 and Galaxy S20, you can assign two phone numbers to one phone.
A SIM card is the essential ingredient for connecting your phone to a mobile network, calling and texting and your telephone number. An eSIM does the same, but instead of a plastic chip that you can remove from your phone, it is part of the internal components of your phone.
Admittedly, an eSIM is not nearly as exciting as aor a camera that but it is an essential part of our Phones. Without a SIM card, our phones cannot connect to our wireless network providers, and that can also be iPods. In addition to technological developments in the field of displays, the SIM card is changing – and it is for the better.
What exactly is an eSIM and why do you care? Glad you asked. Here is everything you need to know about eSIM technology and why it matters.
What is an eSIM?
An eSIM – which stands for & # 39; embedded subscriber identity module & # 39; – is a small electronic chip in a telephone that has the same function as the small plastic SIM cards that we have used for years. Without a SIM card, your telephone does not know which provider to connect to or your telephone number, and your provider does not know which telephone to service with.
What are the benefits of an eSIM?
Unlike SIM-locked SIM cards that prevent you from switching between providers, an eSIM can be programmed and reprogrammed if necessary, so that you can switch between providers or cancel and start the service without a new one each time get a SIM card.
Without a removable SIM card drawer and the valuable space that this requires, phone makers can press larger batteries into the housing of a phone or use the extra space for additional cameras & new features. Of course, no sim card slot probably means no microSD card slot for adding extra storage, a change that phone manufacturers are migrating to. providers and telephone producers need to be streamlined (more on both aspects below), but one thing is clear: we will soon be able to switch between providers with a few taps on the display of our telephone.
Which phones now use an eSIM?
There are not many phones that currently use eSIM & # 39; s.
- Apple & # 39; s all have an eSIM, in addition to the standard plastic SIM card (more about why below).
- also have a standard SIM card slot and eSIM support.
- has an eSIM and a Micro SIM card drawer.
- The is the first phone to be launched without a physical SIM card slot and relies solely on eSIM.
- Samsung & # 39; s have a standard SIM and an eSIM, just like the Galaxy Z Flip. The eSIM functionality may not be present at the launch, but will be activated by a future update.
Why have an eSIM and a physical SIM card?
with two SIM cards – an eSIM and a physical card – can connect to two different providers and phone numbers at the same time. So you can have your personal and business number on one iPhone, even if you have T-Mobile and Verizon as providers respectively. This is possible on an iPhone because it is unlocked and supports multiple providers.
Phones with eSIM & # 39; s are also useful for frequent travelers: you can use the eSIM to sign up for a data plan abroad and protect yourself against roaming charges. And if you set up an eSIM via a provider such as GigSky before you leave, you have data access as soon as you land.
Of course, you do not have to use both SIM cards at the same time, or not at all, and when you purchase the phone from your provider, it is usually supplied with a standard SIM that is already installed and ready to connect to your account. .
However, if you buy a phone that does not have a SIM card, you must go to your provider at certain stores or websites such as Swappa or order a SIM card and wait for it to arrive in the mail, then activate it. With an eSIM you don't have to wait – you can activate the phone in a matter of minutes.
