I just downgraded from cyanogenmod 11 to 10.2.1 - and I found everything works perfectly except for sending sms. E-mails, phone calls - even receiving sms is fine. I try to send an sms and it just gives me a notice saying 'message not sent'. If i look for more details it says 'error -1'.
I've done some googling and found somewhere on another forum that someone else said this was a problem with voice plus in non google voice countries. He didn't say how to fix it though. I've tried uninstalling voice plus, but it didn't seem to work.
I'm based in the UK using three mobile. Everything works fine on cyanogenmod 11 and touchwiz - I downgraded because of the stability issues in the latest cyanogenmod snapshot. Tried Slimrom but it wouldn't load on first boot for some reason.
If anyone could tell me his to get this working in be very grateful.
Thanks a lot.
