I know this question has likely been asked before (I've searched but have only found a generic answer) I am wondering if someone with my same carrier has been successful using their phone on the island. Our Tmobile phones are 4 band with sim cards, how (if) do we proceed to use them while there? I have read in the past they have to be BTL compatible, does that have to do with the band? I am not too tech savvy but would like to be in communication with others while on the island and to check in here at home.
Thank you!
