So my mother who is on T-Mobile is eligible for an upgrade on her account. However, she does not want a new phone is and definitely not interested in a smartphone. Because of that, I want to take advantage of that and use her upgrade eligibility for myself. I am on Verizon, so the S2 won't work for me, so I will be looking to sell the phone. My question is, is there a way to upgrade without getting a data plan? If I buy the phone online, every site requires a data plan. If I don't ever put in my mother's SIM card in the phone, will she still be charged the data plan. I just don't want to mess with her plan and not be able to go back to the one she's on now cause I'm not sure if it's a plan that is still offered. Any help would be great and thanks in advance!
