iMessage on IOS 7 not working over cellular network
Good afternoon everyone.
I have a problem with iMessage on IOS 7 that, as far as I'm aware, only started in the past few days (possibly since the recent 7.02 update). I think it's slightly different to all the other problems described on here and I've tried those fixes but without success.
Essentially iMessage will not send (or receive, I think) over cellular network. When I try to fix this by turning it off and on (with Wifi switched off) I get told that it can't be turned on as I need to activate cellular data, but it is activated.
The only way to turn it back on is with Wi-Fi enabled. But then as soon as I turn that off to simulate being out without a wireless connection, iMessage doesn't send.
Any advice gratefully received!
Many thanks in advance
