It should only take one working day for your number to be transferred. It’s that quick!
If you have given us your PAC code before 5pm, Monday to Friday, your number will be transferred the next working day. If it was after 5pm, or during the weekend, it’ will take two working days.
You will be able to tell when the transfer has started as your old SIM will stop working.
Just to let you know: If your transfer is over a bank holiday, it will take two working days, as these don’t count as working days.
