Use PAC unless you actively want a new number. Porting costs nothing, and a number you have had for years is worth keeping.

What it means for you

Almost every obstacle people meet when leaving is a script rather than a rule.

  1. It cannot refuse to issue the code.
  2. It cannot sit on it or delay it.
  3. It cannot attach conditions to it.
  4. It cannot make a conversation with retentions a condition of leaving.

Retention offers themselves are perfectly legal and occasionally very good. They simply cannot be a toll gate. Get the code first, then listen to the offer with it already in your hand — that way you are choosing rather than asking permission.

The right order to do things in

The facts

First
Check coverage at your postcode
Second
Buy the new plan
Third
Text for the code
Fourth
Hand it over
Fifth
Keep the old SIM in until it moves

What it means for you

  1. Check coverage on the new network at your own address.
  2. If anything is uncertain, test it on a rolling month first.
  3. Buy the new plan.
  4. Text for the code and read the itemised reply properly.
  5. Hand the code to the new network and leave the old SIM in the phone until the number transfers.
  6. Diary a check that the final bill closes at zero.

What it means for you

Put it in writing — app transcript, email or letter — with dates, facts and the outcome you want, and keep the reference number.

At eight weeks unresolved, or immediately on a final response, the case goes free to the Communications Ombudsman.

Watch thisIf you are with a brand that rents masts, every part of this goes to that brand and never to the network that owns the infrastructure.
