@teezeh i live 40% of the year in germany and 60% of the year in the usa. i can't do banking in germany unless i can get SMS on my german number. i could technically throw my german sim into another phone but i already travel with 4 phones and i like not having to switch phones when i switch continents.
@teezeh also if my phone is damaged in the usa, i don't know that i can get a new german esim remotely.
