Hi - I got a new hand set and needed a new nano sim for it. I was told to phone back to swap phone number when it arrived but now you cant get through and was advised to chance number via 2202 text service. So I put new sim into new phone and text swap from the new sim and entered the serial number from my old sim (number i want to keep). Firstly have I done this the right way around? Secondly I did this at 5pm last night (friday) both phones stopped working shortly after but it is now 10am Saturday morning and they are still not working - both have no service and pay as you go helpline closed until monday. Can anyone advise??? Thank you
