Thanks for help
this message come across to me.
We've tried to process your PAC, but there is an issue with the information you've submitted. Please check that you have provided the correct details and try again.
If you have already used this PAC code and submitted it when purchasing a handset or SIM, don't worry - your switch is underway. We'll send you a text as soon as your number has been transferred to us.
I am intending to keep my old mobile number and change to ID mobile.
please help!
