sim card
I have a 4G compatible phone but the sim card I am using is from before 4G. Will I need a new sim card when 3G shuts down?
just make sure the phone has VoLTE capabilities..if it does not then it will not work even though its a 4G phone..
VoLTE=Voice over LTE..as of right now if you do not have VoLTE then all your calls and regular texts use the 3G side of things to send/receive.
