Lumia 640 SMS Center Number

I have an AT&T Go Phone, the Lumia 640, and I can't send text messages.  Some how in the settings the SMS number is gone. 


I tried pulling every number off the SIM card and none of them work.  Please help!  🙂  I even tried reseting the phone and that didn't work either. 😞

Hi @whildt


I can help you get that SMS Center number back and we’ll have you up and running in no time!
The default Message Center Number is +13123149810. It’s important that when you enter the number you enter the “+” as well as the 11-digit number.
Hope this helps and let us know how it goes!
