No More Tiny Plastic Cards: The Future of Phones innovation

​For a long time, we have used small plastic "SIM cards" to connect our phones to a mobile network. Even though they have gotten smaller, they are still a bit old-fashioned. Now, big companies like Apple and Samsung are working to replace them entirely with something called an eSIM. ​

What is an eSIM?

​An eSIM is a "digital" SIM card that is already built inside your phone. You can't take it out, and you don't need to.

​Why this is great for you:

​Switching is Easy: You can change your phone company or plan instantly through your phone settings. No more waiting for a card to arrive in the mail.

​Perfect for Travel: If you go to another country, you can sign up for a local data plan "at the drop of a hat" without needing to find a phone store.

​More Space: Removing the card slot gives engineers more room to add bigger batteries or make phones even thinner.

​When is it coming?

​This technology is moving fast! We expect to see many new smartphones using this digital system starting as early as next year.

​The bottom line: The days of hunting for a paperclip to open your phone are almost over. Your connection to the world is going digital.
