Over the past few days, several iOS 7 users have been reporting issues with sending and receiving iMessages. A quick (partially successful) fix has been to Reset Network Settings inside of the iPad, iPhone, and iPod touch Settings app. However, this mostly has only been working for outgoing iMessages.
Instead of sending as an iMessage, texts have either been reverting to SMS or just hanging without ever sending. Now, Apple has told the WSJ that it is aware of the issue and it is working on a fix for an upcoming software update:
In the meantime, Apple is recommending that users contact AppleCare. We’re not so sure that will solve anything as this is clearly a software issue that Apple has acknowledged (in the same statement!) will be solved with an actual update. As our own analytics have shown, Apple is widely testing iOS 7.0.3, so perhaps this will be the release with the answers to our iMessage troubles.
