For the first time in many years, I've bought my phone from AT&T instead of a European dealer. In the past, I've just taken the SIM card out of the old phone and put it into the new one. With this GS 6 Edge, AT&T sent a new SIM card, but with my old phone number on it.
Is there going to be any difference in service or performance between the new and old sim cards? Thanks.
