If anyone rings new number they get you have dialled a wrong number etc etc if I ring out from mobile it comes up giving out old number I had... if ppl ring it back it says you have dialed a wrong number..if ppl ring the new number it tells them aswell u have dialled a wrong number...... If I send a text ppl can text me on new number that's it... I've rang them everyday for over 2 weeks and getting no where I'm paying for a mobile I can't use it as no one can get me I have a lot of medical conditions and need this working ASAP..

@Pep4d: I'm really sorry to hear that you're experiencing this issue. You mentioned that putting your SIM into another phone produced the same error. If this is the case then the problem lies with your network or current SIM, therefore I recommend getting in touch with your mobile network directly to report the problem and arrange a SIM swap to see if this helps. I understand that you have been in touch already, however if the problem is occurring on multiple devices then it needs to be addressed from their side.

Cancelling your direct debit you will need to be careful, as there will be consequences
If you have a contract with them and you cancel the DD, you may be liable to pay the full cost of the rest of your contract or cancellation fee's etc.
As well as possibility of affecting your credit rating.
Personally I'd see if they can send you a new SIM card with the new number. They can also send you settings to save to your phone
I take it you got the phone through them and it's an unlocked phone.
If its carrier locked to another network provider, you will not have proper use of it
