Hi everyone. I just switched from ATT with my unlocked iphone 4. Here is what happened: I received my sim cards yesterday in the mail. Put it in and everything was working fine. Today, I connected my phone to iTunes and it offered a carrier update which I downloaded.
Now, whenever I open my messages, a notification pops up saying that "MMS messaging requires phone number, go to settings and enter your phone number". When I do so, it says that the phone number cannot be saved.
This is happening on two sim cards that I received. I assume the carrier update screwed something up because it was working fine last night when I first inserted the sim card. I didn't check if it listed my number, but MMS message wasnt showing up. Any possible solution?
So far I tried: resetting all settings, resetting just network settings, airplane mode on/off, wifi on/off, 3g on/off, sim card in/out, restart phone, hard reset, tried a different sim card in too.
I doubt it has anything to do with the phone or iOS because When I put my ATT sim card back in - the phone number shows up right away.
My Cellular data settings (MMS too) became fast.t-mobile.com after the carrier update.
I dont know what they were before, but I also found a document here and tried the epic.tmobile.com version. Nothing happens.
any comments from the tech guys?
This is a strange situation and it's not one that we've heard of yet. The carrier update, believe it or not, is not responsible for this. The APN that you have is correct, either of them. I believe that you will want to contact Apple support to determine why this has happened.
I have the same issue. Read below, I know they didn't fix your problem.
EVERY single time I go to my text messages, it states "MMS Messaging Requires Your Phone Number" it gives me two options [Cancel] [Settings] and also says "Press settings to go to Phone Settings and enter your phone number." When I tap settings it pulls up my phone settings and says my number is unknown. I then tap it to manually edit the number and put it in and then tap save. At that point is says "Phone number could not be saved." I've tried many different routes to fix this including calling Apple. They told me it was a problem with T-Mobile's sim card, not being read by the Iphone 4, I was told I need to go to a T-Mobile store to have them update my sim card. I went to the T-Mobile store, and the gentleman there told me that he had no idea what to do and looked on these forums saying that it is a known issue and T-Mobile is probably working on it. I don't believe that because every single post I have seen about this is exactly the same "Call apple". Is that you guys giving up on helping us out? Please help me find a viable solution to this problem, it's extremely annoying. Thank you.
I am having this problem as well -- jsititely described it exactly. I will already have to switch carriers if this cannot be resolved as I need my phone to work NOW
i know this has already been answered, but that answer didn't work in my case. same problem as far as moving from at&t with an iphone (4s). "mms messaging requires phone number" but "phone number cannot be saved". i contacted t-mobile support and pointed out this thread, but nothing got fixed from it. called back later, and what fixed mine was resetting the network. settings -> general -> reset -> reset network settings. just in case someone else wants to try this as a troubleshooting step when looking up this thread.
Hello! If anyone is experiencing this concern please Contact Us over the phone (we do ask that you call from another phone) or via Live chat so a specialist can assist in resolving this as quickly as possible.

Thanks so much!
I sent an email with the info following exactly what @tmo_maria's instructions. Nine minutes later I got a text from 511 with a welcome message and "Your mobile number is 1xxxxxxxxxx". I then check under Setting -> Phone and My Number now has my phone number in it. Not reboot needed. It was so easy and quick. Thanks T-Mo. You guys ROCK!!!
This worked for me. Thanks!
I am also having this issue. Where do I email this request?
