okay, so i recently broke my lg xenon and i am looking into getting a replacement phone. here are my options, i can pay the $50 deductible and get a phone i dont necessarily want (they no longer make the xenon) or the get something else, but that's be on me. my mom is currently due for an upgrade, is there anyway i can use her upgrade to get me an htc aria, while she keeps her old phone? the only thing that we are very concerned about is what the data plan is connected to, is it to the sim card or to the actual device? if anyone could help, that would be greatly appreciated
