What is eSIM? is

An eSIM, or embedded subscriber identity module — is a small electronic chip inside a cell phone that serves the same function as the small plastic SIM cards, which we used for years.

What are the benefits of an eSIM?

in contrast to carrier-locked SIM cards, carriers of an exchange between the transport, an eSIM can be programmed and reprogrammed as needed, so that you get to bounce between the airlines, or cancel and start service without a new SIM card each time. 

Without a removable SIM card, and the precious space that requires it, mobile phone manufacturers will be able to squeeze larger batteries in a cell phone case or you can use the extra space for additional cameras or new features. Of course, no SIM-card slot probably means that there is no microSD card slot for additional memory, a change, the phone-makers, the Migration direction.

The eSIM is still young, and as such, the process for things such as activation and support of carrier and phone can display manufacturers need to be streamlined (more on these two aspects further below), but one thing is clear: One day, soon, we will be able to switch instantly between the airlines, with only a few clicks on our phone.

Why have eSIM and a physical SIM card?

Apple iPhones, which can connect with two SIM cards-an eSIM and a physical card — to two different carriers and mobile phone numbers at the same time. So you can your personal and business number on a iPhone, even if you have T-Mobile and Verizon Wireless, respectively, as a provider. This is possible on an iPhone because it is unlocked and supports multiple carriers.

phones with eSIM are also handy for a lot of travelers out of the country. You can use the eSIM, sign up for a data plan abroad and save yourself from the roaming charges. And, if you have an eSIM through a provider like GigSky, before you leave, you need to access the data, as soon as you land.

Of course, you don’t have to&on both SIM cards at the same time, or at all, and if you installed buy the phone from your network provider, it usually comes with a standard SIM and ready to connect to your account.nbsp;

However, if you buy a phone that is not with a SIM-card — of selected dealers or websites such as Swappa, for example-you need to be on your carrier or SIM card, and wait for it to come in the mail, then you get activated. With eSIM, you don’t need to wait – you can activate the phone in a few minutes.

all phones to begin with eSIM-cards?

odds, Yes. It makes sense for the phone maker and carrier, ditch the plastic SIM cards, both of which are of an additional cost point of view, as well as the environment if you consider the large plastic card that adds a standard SIM card comes attached to it. 

my carrier Has to use in support of the eSIM technology for me?

” Yes. Apple has a list with all the cellular providers around the world that support the iPhone-eSIM function. 

As for the Google Pixel, the process is a little confusing. Google-Fi, the Google prepaid wireless carrier, can an eSIM, and some of US to support carriers like AT&T and Sprint eSIM to the Pixel 4, but not on older Pixel mobile phones. 

When I try to add a eSIM mobile-plan, my-Pixel-4 XL now that I’m given the opportunity, the AT&T, Sprint, and Google Fi. 

It seems to be hit or miss, if it supports the carrier of the device, and it is even more confusing when you start looking into dual-SIM support.nbsp;

If you have a Pixel-by-phone, and you want to take advantage of eSIM functionality, it is a good idea to contact your mobile provider and ask them about the eSIM-support for your specific model.
