Hi Ian. Welcome to justanswer.
Which network's services are you using?
Is it vodafone?
Go to Settings- Network Settings. Try changing the network type to GSM.
Have you tried changing the network settings?
I was asking about who is your mobile network carrier? Is it O2, EE, vodafone, virgin etc?
Yes it would be extra but don't choose that as this is your network's issue and accesing your computer won't resolve it.
Go to Message app. Select settings there. Tell me what options are you getting.
Go to your message inbox. Select options. Do you see settings there? Find MESSAGE CENTER NUMBER there.
When you select message icon, tell me what options do you get.
Do you see a list of options like Write message, inbox, outbox, draft etc?
Hi, just checking in. How did things turn out?
