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 guess I am at the same point than all of you :

Answer from Apple Singapore today was that they ( engineer team ) are investigating on the problem, I've asked them to be more specific but they've stayed really generic on the answer. At least I've been confirmed that the phone is listed as "unlocked" in their database.

So yes if this is a technical issue we have to wait the update if an update can solve the problem

Demirmkn,


There is no support by email for this, you must call them and report the problem by phone. You can call them for free from a @gmail.com account, using Google Talk integrated in browser. The phone number to call is +1-800-694-7466.


As Nav33d here already outlined the list of the things we have tried already, so you know what to tell to support, as they will ask you to do these things:


1) Calling Sprint (you probably paid the 'unlocked' price and as a result won't have an account with them so they know nothing about you/your phone).

2) Calling your carrier (if they're outside the U.S). The problem is with the phone having a lock on outgoing SMS.

3) Resetting Network settings.

4) Using the *#5005*7672# trick to reset the message centre number.

5) Restoring from iTunes/Backup.

6) Restoring as a new phone.

7) Removing sim, putting sim back in.

8) Resetting phone.

9) Tinkering with iMessage/MMS settings.

Roman, I am not sure they can make an official announcement as it's seems really non official in there communication that these phones bought "off contract" are also "unlocked" out of the box for international use without any interaction with the carrier ... Even the top community guys here didn't know, neither Sprint .... It's really strange, I don't understand the huge gap between there communication and the facts.

Found this on the web... works for me...

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
