My iPhone 5s won't send texts

[Anonymous]

It's only happened today but my iPhone won't send a text to anyone... At ALL!!
I can call people and receive calls easily and I can receive texts but I can't send any!!
I have a string enough signal to send but it won't at all.
I've tried restarting my phone, resetting the network connection, turning aeroplane mode on and off and it still won't send.

Any help??

Hi

Try a reset of your iPhone by ;

Holding the Top Sleep/Wake Button and Home Button until the Apple Logo appears, and then let go of both. Your iPhone will reset.

And or ;

Settings , General , Reset , Reset Network Settings again.

Check with O2 Cs ref your account.

Also check your service status http://status.o2.co.uk

Remove and clean your sim.

Remember you need data connection to send iMessages and mms.

Have you changed sim card recently at all.
What is your message centre number set to?
