eSIMs are pretty useful because for starters, they won’t need a physical SIM card slot which means that less space is taken up in the phone which could be used for other features, like a bigger battery, better cameras, better thermals, and so on.
It also means that users don’t need to worry about losing their SIM card and could make dual SIMs a lot more efficient. The good news is that if you live in the US and own the Samsung Galaxy Z Fold 2, you might be interested to learn that in the latest update for US variants of the phone, both carrier and unlocked versions of the handset, it looks like eSIM support is finally here.
Once users download the update (build number F916USQU2HVF1 for carrier variants and F916U1UEU2HVF4 for unlocked variants), they’ll be able to start using the eSIM right away. In addition to eSIM support, the update also introduces Dual SIM, Dual Standby (DSDS) support.
This means that users will now have the option of being able to use an eSIM and a physical SIM at the same time. This is useful especially for traveling, where if you go to another country that might not support eSIM, you’ll be able to use a local physical SIM while still maintaining your main line in case anyone at home needs to reach you.
The update should already be live and also brings about a bunch of bug fixes and improvements, so it is definitely worth updating when it becomes available for your handset.
