iPhone 5 can't send SMS - gets an error when sending SMS

People - I'm using a Sprint iPhone 5 with my local GSM chip. Everything works fine, except sending SMS.


All basic troubleshooting has been done: checked SMS settings, erased Network Settings, checked SMS Service # through *#5005*7672# and it is fine, restored the phone and re-checked everything above again... and nothing. :-(


Please help?

iPhone 5, iOS 6, Sprint model (A1429), GSM Network

I got a Sprint iPhone 5 on contract and then called sprint and told them that I needed to get the phone unlocked cuz i was going to travel to Mexico City. i did this with my iPhone 4s and I never had a problem with it overseas. Sprint NEVER said they can’t unlock it, in fact the international department was very nice and said "yes, just restore it and you should be fine" i did that and i got a message on iTunes that said that the iPhone was unlocked.


When i called to do the same with the iPhone 5 i got the same response but this time when i did the restore, the iPhone is unlocked message did not come up. i called sprint again and they said that they were having problems unlocking the iPhone 5s and that they send the request to apple but never get a confirmation that the device is unlocked on their end like they did with the 4s.


They told me they would contact me later and eventually a manager emailed me and asked that I do the process again. I had the same result and just left for my trip, when I got to Mexico City I put in the sim card and the phone started working no problem, so i thought that the phone had been unlocked successfully. Unfortunately I have the same problem that you all do and I can’t send sms to anyone.


From what I can tell this IS an apple problem as sprint is more than happy to unlock the iPhone for anyone that just calls them. i think the problem is that apple did not lock the phone from the factory or did it but not completely, and now is not offering a solution to the problem. The sprint manager told me himself that they have no problem unlocking the phone but that the system they have in place to do it is not working with the iPhone 5s.


so i think until apple fixes that and truly lets carriers unlock the phone? We are not going to be able to do anything about it.... All tho if someone needs a test subject to try to fix this??? I offer my phone and will try anything at this point hahahaha

I had the same problem but was able to find a temporary workaround until Apple/Sprint releases some kind of fix. It's not perfect, but it gets me by for now. worked for me, but I don't know if it'll work for every locale:


I am outside the US and trying to use a GSM SIM card in a Sprint iPhone5 but could not send SMS messages (only receive)


Try this:


1. Go to Settings / Messages

2. Make sure "Show Subject Field" is on

3. Try sending a message but type your message in the subject heading instead of the main box. The key is that the subject line has to have something in it, even a " " blank space will do


I tried sending it this way to other iphones and smart phones and both the subject and body of the SMS would go through, but to older cell phones only the subject heading goes through, and only the first 39 characters.


Hopefully Apple/Sprint will come up with an actual fix, but I'm hoping this is of help to some people out there

I've Open the case for this specific Issue, call the Call Center, they said they need to double check with Carrier, and able to send me some way to troubleshooting.

So, as few information I've got from both Sprint and Apple, look likes apple will need to take responsible to resolve the case.


Because without any-contract, Sprint cannot support us for this case.

Any other update from you guys will be appreciate.
