Hi, folks, the other day i forgot my ZTE ZMax Pro charger at mom's home, i dont have another one, so i realized my battery was about 1% and then tried to get the charger and... well it was not there. anyways, i have an oldie phone (Samsung Galaxy Note 2 N7100 unlocked) and tried to swap simcards, but the simcard from metro didnt work. i tried another phone from metro PCS and either worked! those phones are not LTE, and the simcard that i am trying to use i think is LTE, do you think that that's could be the problem??? i am very sure my celphones are unlocked because i used to use them abroad all the time. please any help would be aprecciate it
