Traveling is simpler, because you can activate multiple numbers on the same phone. In the past, only those phones with room for two SIM cards, also known as dual-SIM phones, could have multiple phone numbers. Such devices were rare in the US, but eSIMs have now changed things because they’re fully programmable. For instance, current iPhones support eight stored eSIM phone numbers and two active ones, so if you’re traveling, you can simply download a new SIM to your phone. And if you change carriers or just want to change your number, you can do that as many times as you want, though how simple the process is depends on your carrier and your smartphone manufacturer. If you have multiple numbers or travel frequently, an eSIM should make your life a lot easier.
