the canada/mexico iphone i bought (because i need a sim card slot) doesn't speak the 5g bands used in the usa. if i get the one that speaks the 5g bands in the usa, i can't use my german sim card because those don't have sim slots. cool.
@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.
