So I have had an iPhone since the beginning on a FAN account, and the day that I bought my 3G I called ATT to add the TMS4 text messaging plan, which gives me 1500 text messages for $8.99/month. This has been on my account since July of 2008. Fast forward to this year. I buy the iPhone 3GS on launch day from the Apple store. I look on my ATT wireless online account and apparently I am being charged per text message. I don't have ANY text messaging plan on my account anymore. I called ATT yesterday and asked them why I am being charged per text, since I was under the assumption that I had the TMS4 plan on my account. She told me that the TMS4 plan was not compatible with the 3GS, and if I wanted 1500 text messages it would now cost me $15/month. I told the agent that I did not authorize the removal of TMS4, and that she should put it back the way that it was. She told me that she tried to put it back, but the system would not let her do this since I have an iPhone 3GS. I asked her to give me a $6/month credit for the difference between the existing text plan and the TMS4 plan, but she refused. So...I am sure that I am not the only one that was using the TMS4 plan, so if anybody has experienced this, what have you done about it? I am open to all ideas!!
