for some time now I have not been able to make calls or text my phone.

[Anonymous]

My phone constantly comes up with the message no service, not registrered on network or emergency calls only.  I am not happy because this has been going on for sometime now hence I have not been able to make important calls or texts.  I am on pay monthly tarrif and I am still being charged.

Check your postcode here for any network faults or maintenance etc http://status.o2.co.uk/
There is also a help thread here to work through to help identify the issue https://community.o2.co.uk/t5/Pay-Monthly-Pay-and-Go/How-can-I-sort-out-my-network-issues/ba-p/10140...
You will still be charged as per the T&C's but if it's a network fault you may get a refund for downtown as a gesture of goodwill once the issue is resolved.

If there is a mast problem don't forget you can use TU over wifi at home or in the office.

only if you have pre registered

otherwise you will need to be able to get a security text.

You'll just have to drive somewhere with a signal.
