we have had t mobile for a few years and they it hasnt really been the best coverage. but now my dad wants to switch to sprint which ive heard isnt any better. i need some help. should we just stay with t mobile or switch to sprint?
Your dad phone supports GSM carriers means he doesn't change his cellphone carrier to sprint.But he will be able to swap other GSM carriers.
If your dad want to change other GSM carrier means,check whether his phone is unlocked or not.locked phone,he wants to unlock phone.For unlocking visit Unlock-Zone.com
