Hi, I currently have a Nokia Nuron on 2-year contract with T-mobile (in U.S.). I got the phone in Sept, 2010. At that time, the T-mobile rep added $10 unlimited internet. I can surf the net unlimited on Nuron including youtube. 2 weeks ago, I moved my sim card to a Huawei T-Mobile Comet (IDEOS). The internet worked only for a few hours. Then it was shut down & redirected a T-mobile page asking to upgrade to a smartphone internet plan. I moved the sim back to Nuron, the Internet worked again. Still paying $10 per month for the Internet. I was wondering if I purchase a Huawei S7 from Best Buy & move the sim card to S7. Will I still have unlimited internet for $10? Does it help if I change the APN to internet2.voicestream.com? Thanks!!!
