E-sim Technology

An eSIM is exactly what it sounds like — an electronic, or embedded, SIM. Instead of a physical card, SIM technology is built right into your phone. It’s a small chip that’s used to authenticate your identity with your carrier.

Of course, you probably have some questions about that. With a traditional SIM card, you had to switch the SIM if you traveled and used a new carrier on your travels, or if you wanted to switch carriers. So does a built-in SIM mean that you have to switch phones? Thankfully, no. In fact, one of the advantages of eSIM technology is that it makes it much easier to switch carriers. Instead of having to order a new SIM and wait around for it to arrive, you can switch to a new carrier straight from your phone. If you’re a dual-SIM user, eSIM technology supports multiple accounts — and switching between them is super easy.
