Trying out a data eSIM for some upcoming international travel

Does anyone actually need phone service abroad??

Having receive ability on your primary line will make things a lot easier, mostly cause you’ll realize a lot of things need SMS 2FA.

This is a great point 

I do use SMS 2FA for some services but usually have an email or Auth option as well

I do too, but a lot of services literally use phone numbers for login these days, and with those there’s no way around it.
