i am currently using a 3G only Droid X2 and plan on switching to a Droid Razr Maxx 4GLTE, the droid X2 does not use a sim card but the Razr Maxx does, the Razr Maxx will be my first 4G phone and sim card phone, i was just curious if my unlimited data will be in tact when i make this switch from a non-sim card 3G smartphone to a sim card 4GLTE smartphone.?
