Transferring Grandfathered Data Plan to New Device
I have an iPhone 3G with a grandfathered unlimited data plan. I was thinking about getting a new phone and keeping the same plan as is. I checked my wireless account and it shows "Data Unlimited for iPhone." I know a phone ugrade through AT&T would require a new data plan along with a 2-year contract, so I'm avoiding that since my contract is over. My question is, if I were to purchase an unlocked gsm smartphone elsewhere, can I just remove the sim card from my iPhone and pop it into the new phone? Would this work? Would this allow me to keep my same plan and everything else? I just wanted to verify before purchasing a new phone. Thanks in advance.
