In need off a PAC code from contract cancelled and left with no service

[Leecollins95]

I need help getting my old contact number back that I have had for many years I moved over from VOXI to a telecommunications company that uses EE as a network provider using a PAC code and the telecommunications company billed me extremely high so because I refused to pay the ridiculous amount they cancelled the contract which has left me with no signal and I need my phone number back I still have the SIM and in my iPhone settings my number still shows up and says it’s network provider is with EE but I don’t have signal

1. As your contract was pre-emptively cancelled you've lost that no. for good.
2. Anyway even tho' that telecoms co. uses EE as a MVNO, it's not in the hands of EE.
3. Anyway your SIM that you still have is now invalid.
