I read this somewhere else concerning out of network texts, give it a shot:My friend just bought an iPhone and he is unable to send text messages to t-mobile phones. Has anyone else had this problem?
If it is a newly activated iPhone (new # or ported) it will take a couple days for the number and it's service carrier to reach all the cell phone traffic servers. If it is still not working after 3 or 4 days, then I would call AT&T.I made a mistake... He is unable to receive text messages from t-mobile phones. He can send to them just fine.
I tried the above solutions however it did not work.
My iPhone has no problems sending/receiving to the same t-mobile number.
You and your friend may have to contact both carriers, but it is most likely on side of whom ever ported their number. Cellular carriers love to forget to update their routing tables for SMS/MMS, not to mention sometimes you run into the problem that the old carrier didn't de-activate the number in their switch.... fun fun fun.. good luck!My friend just bought an iPhone and he is unable to send text messages to t-mobile phones.

By the way Ehspimp.. You're replaying to a message that was posted like a year ago.. lol.. Anyways, I seriously doubt that the problem is on AT&T's side. Most likely on T-Mobiles side. If you have a ported number, that may also be the cause of it... Who ever you ported your number from may have not sent out their updates to the other carriers. But Best bet is to have your friend that has the T-mobile phone report it and he is going to have to stay on them.. And just a ummm word of advice.. It's not the phone having the problem, It has to do with your phone number. I bet if you get a new phone number it will work fine ( If thats a option for you ).I know what u r talking about I just activated my iPhone 2 days ago and i seem to be having the same problem. I called AT&T a bunch of times and they said they reseted my messaging service. But still no luck I even went to the Apple store and told me to restore my phone which I did but that didn't work either. The weird thing is that I can receive textes only from AT&T custumers. I'm going to wait till wednesday and if it still doesn't work i'm returning the iPhone. tell your friend to text the word test to the number 151 from his iPhone he'll get a message from AT&T saying your message service is working but that might not work because it didn't work for me. Let me know if he gets his iPhone working because it sucks not being able to text.
