This is the 3rd time this has happened and it is not possible to send text messages. Fine to receive. Initially you would have to try to send 5 or 6 times before it went now not a chance of it going. This has been going on for over 3 weeks and we thought it may be an issue with the phone instead however put the SIM into new phone and still failing. New phone works fine with an EE SIM card so not an EE issue. Tried reselecting network and all sorts but no luck. Will try to resolve this once more but if it doesn't work, or happens again then I think I will go direct to EE instead!
