MMS issues with Factory Unlocked Iphone 4s

I have a factory unlocked Iphone 4s.


Earlier today, I called Tmobile Tech Support for settings to enable MMS.  The instructions they emailed me are at the end of this email.


Bottom line is that when I followed the instructions, yes, the MMS worked, but the normal text messaging (SMS) stopped working! In order to get SMS to start working, I had to turn "MMS Messaging" to off.


Here's what Tmobile sent me, and again, my Iphone is factory unlocked but not jailbroken, so I can't go the Cydia route:


Any help appreciated.




  1. Tap Cellular Data Network
  1. Configure as follows: 
  2. APNepc.tmobile.com
  • Username: <Leave Blank> 
  • Password: <Leave Blank>
  1. Enter the following information under the MMS section:
  2. APNepc.tmobile.com 
  1. Press the Home button to return to the Main Menu. 
  2. Press the Homebutton to save the APN and exit to the main screen


Verify MMS is enabled:


  1. Tap Settings
  2. Tap Messages
  3. Tap MMS
  4. Set MMS Messaging to On


Then powercycle your device and test it.
