Samsung already offers a version of its Gear S2 smartwatch with support for 3G data. But soon the company will launch a new model that can be used on just about any wireless network, thanks to an eSIM.
Here’s what the means: you can buy the upcoming watch and use it on AT&T. But if you decide to switch to Verizon in the future, you won’t need to buy a new watch or a new SIM card. The eSIM can be reprogrammed to work on a different network.
If this sounds familiar, Apple’s been using eSIMs in some of its products for a while, but the company uses its own platform instead of a GSMA-compliant one.
Note that you can still only use an eSIM with one network at a time: this isn’t a dual-SIM solution. But if the technology catches on, it could make it easier to switch wireless carriers without necessarily switching hardware.
