iMessage on 3G connection

iMessage will not allow me to send messages over an AT&T 3G connection, every message is marked "Unable to send" after a short time. However, when my device is connected to a WiFi network there's no problems with sending anything at all. I get the option to send as SMS, but it seems to convert the message to an email which it delivers to the recipient.


Additionally, messages are not received when on 3G but flood in as soon as I hit a WiFi connection.


I've been through the process of switching iMessage off and on, signed out of it and back in, restoring the phone and ensuring my phone number matches my Apple ID details.


Any advice would be appreciated.


Device: iPhone 4, OS: iOS 5.0 (9A334), Carrier: AT&T

I had the same problem as well and found a solution that worked for me :

First I did probably like you and upgraded to ios5 and then restored all items on my iphone through itunes. Then I had the issue with imessage over 3G.

So I restored my iphone through itunes but then set it up as a new one and then it all worked fine.

To make sure this was the issue I then restored it to a date prior to the update and upgraded and restored like I did the first time and then I had the issue again with iMessage, so I did a new iPhone again and now it is working fine again.

Some bug somewhere probably in the upgrade process...

Hi guys,



I had the exact same problem on my iPad. iMessage worked perfectly over wi-fi, but I never could send or receive messages over 3G. The progress bar got stuck at around 90%.


Turns out, it was a misconfiguration of the APN settings for cellular data. The default settings that appeared in my iPad differ from the recommended ones (http://www.swisscom.ch/res/hilfe/internet/ipad/gprs/index.htm, in my case the username and password fields were not empty). Somehow, 3G always worked fine for everything else but this.


I hope this information is useful for you. I have been struggling with iMessage and know how exasperating it can be...

I have the same isue and restored last night. When I set up my phone as new, it worked correctly. As soon as I restored my settings, it stopped working again.


When you set up as new, you lose ALL settings, apps, texts, etc... and I'm just not willing to do this! Is there any other way to revert your system settings to the default to fix this bug without losing all of your personal data?
