When you made the upgrade from 2.2 to 3.0, it relocked your phone to AT&T. You'll have to unlock your iPhone again to get it to work.

Goto your phone's network/internet settings and try the following:
  1. In the APN field, enter either epc.tmobile.com (or internet2.voicestream.com if that doesn't work) -- this tells T-Mobile which version of our Internet network you want to connect to.
  2. Leave the Username and Password fields blank -- T-Mobile will assign this information based on your SIM card information.
  3. Return to the Main Menu and open your browser to browse the Internet.

Wont let me txt or call,says emergency calls onlt


The issue is that your phone is not recognizing your sim card/ is not programmed to your carrier. The way to fix is to contact your carrier and either get the phone programmed to your carrier (Sprint, Nextel, Verizon) or get a sim card for your account (ATT, Tmobile)

Unlocked verizon blackberry world phone wont work with t-mobile


i believe i had had the same issue.

i unlocked an at&t phone and put in the sim card and it wouldnt work. i called tmobile and the representative told me that they have to register the sim card to their network or something.

so just call tmobile and tell them you got a new phone and want to register it so the sim will work in the unlocked phone.

Non tmobile sim card?


I assume you are asking about unlocking your phone. If you are a tmobile user than any tmobile sim will work in your phone even if your phone is locked. When a foreign or different compatible sim is inserted your phone will ask for the unlock code if your phone is locked. When you have an unlocked phone it automatically accepts the sim and does not ask for the unlock code since your phone is unlocked.

2 Problems..Sim Card Problems


Well, first off, an iPhone won't work at all with a T-Mobile SIM card. American iPhones are locked to AT&T's network -- only AT&T SIM cards will work in them.

As far as activating it with AT&T, make sure that the iPhone isn't connected to the computer while you install iTunes. Once iTunes is installed, connect the iPhone to the computer and iTunes should launch automatically and begin the activation wizard. Just follow the instructions on the screen and answer the questions.

Changed service, can't receive a signal


ATT runs off of the 850 mhz bandwith while tmobile uses 900. The old phone you are using uses tmobiles bandwith and only catches 850 occasionaly. I would suggest trying to get an upgraded from ATT when you signed the contract
