Even if you aren’t tech savvy, chances are you’ve at least heard of a Subscriber Identity Module (SIM) card. They’re the small cards located in your phone that help you connect to your wireless carrier’s network and use your plan.
Now, embedded SIM cards (eSIMs) are in the spotlight. While you may not be sure how they’re different than physical SIM cards, why you might need them, which devices have them, and how to use them, we’re here to help answer those questions.
What's the difference between an eSIM vs a physical SIM card?
An eSIM is a digital version of the physical SIM card—identifying your device virtually to provide network connection. It’s programmable remotely via software and is built into newer smartphones, meaning you wouldn’t have to go purchase a new SIM card if you wanted to swap phones or wireless carriers. eSIMs are used in tablets, smart watches, drones, and even cars. They’re basically space-saving gamechangers for connectivity.
What can eSIMs do?
Since they’re embedded in devices and are programmable remotely, it can open a whole new world of flexibility when it comes to managing your phone and service plans. You can add plans, add a new number, and even connect to a different carrier. For example, you cantest outT-Mobile’s network for FREEbefore you switch, while still keeping your current phone number and carrier. Additionally, you can easily switch to a prepaid plan on iPhone with ourT-MobilePrepaid eSIM App.
How can eSIMs benefit me?
Let's say you have one smartphone for work and a second phone for your personal life. If your device is equipped with eSIM, you can have both lines hooked up to the same device, giving you the convenience and control to toggle between those lines straight from your phone. This saves you money because with eSIM, you don’t need two separate devices.
Small, medium, and largebusinessescan benefit from eSIMs, as they make it possible to change or update wireless service remotely on multiple lines at once—whether you have five employees or five thousand.
If you’re traveling internationally, you no longer need to buy a second physical SIM card when you arrive at your destination. eSIMs let you easily add an international plan to your device that starts working the moment you arrive in another country, giving you hassle-free flexibility.
When it comes to the Un-Carrier (that’s us!), perhaps the biggest benefit of using eSIM is that you cantry our network FREEfor three months before you switch.
