Hi there and welcome Robert
Can you tell me what happens when you try to make a call or send a message please?
ok, and when making a call?
Can you hold the power button on the phone till you see a menu and choose power off.
Then when its off, power it on and try to send a message
Tell me if it then sends please.
Can you go to Settings, Applications.
Swipe to the list All and locate Messages.
Press it and press Clear Cache (Not data)
then locate Google Services Framework, press it and press Clear Data.
Restart the phone and tell me if it will now send please.
You skipped the steps
go to Settings, Applications.
Swipe to the list All and locate Messages
ok, the phone has an older firmware on it, hence why you do not have the option.
If you make a new message as opposed to replying, and send it, does it send?
ok, can you remove the SIM card from the phone
Rub it on your sleeve and then put it back in the phone and turn on the phone and send a text.
ok, we will need to reset the phone.
This is going to remove all data and return the phone to new, but we cannot avoid this sorry.
To do the reset
Then set it up again and try to send a text.
Let me know the results please
its the code I gave you in bold, you dial it like dialing a call as per the instructions please.
Your searching for contacts.
you need to dial it like you are dialing a phone number and ensure you use also the special symbols at the start, middle and end that I indicated please.
ok strange, but try this way please
Then setup the phone again
yes, as we discussed, it will remove all data but you cannot avoid this.
You can leave it in
ok, now test and tell me if you have the problem please
ok, looks then to be your account on the server.
Is AT&T your provider?
ok, call them on 1(###) ###-####/p>
Have them check your account and remove any blocks from sending.
Then restart the phone and try to send
Let me know the results please.
