How can we start 4G data instead of 3G data in iPhone5
Your carrier must offer it. Does yours? Is your carrier compatible with 4G on the iPhone 5?
If 4G service is available from your carrier in the area where you are it will show on the phone. You do not have to set it up special or turn it on. It will be there if its available.
what carrier do you have? if its sprint then they don't offer much 4g
