Whats happened is I upgraded from my s21 ultra to s22 ultra. the s21 ultra (T-mobile) is completely unlocked. the phone is completely paid for even did the permanent unlock thing. I gave my dad the old phone because he needed a new one. he put a Verizon (straight talk) sim. the phone works great, save for on massive issue. he doesnt get mobile data, as in he cant use the internet or any internet features without wifi. yet he can make calls and send texts. can someone help me? does he need to transfer everything to a t-mobile sim card?
