My phone is acting up, and tmobile wont exchange it or let me get a new one; so I decided to take a different route and get a cheaper phone off ebay or something.
At some point though someone had told me that if i buy a phone from somewhere not the tmobile store, then I can't use the internet on it? Or something like that. Basically what I'm asking is, if i get a used smart phone off ebay or somewhere, can i still use the internet from my plan?
