Your mobile or SIM card comes with its own phone number printed on the box, but if you’d like to keep your existing mobile number you need to transfer it from your current network.
Just follow these steps, to port in your number:
- Contact your existing network and ask for a PAC (Port Authorisation Code).
- Once you have your PAC code click on the image above.(Please note: Your PAC is only valid for 30 days, so please call before it expires.)
We'll then transfer your existing number to your Tesco Mobile phone.
Your Tesco Mobile takes about 1 working day, we'll send you an email confirming when the transfer will be completed.
On the day of your transfer, your phone number will be moved across to your new SIM card and you will loose network signal. When this happens:
Switch off your phone
Put the new SIM card into your phone
Switch your phone back on
When I transfer to Tesco Mobile will I lose the credits I still have with my old network?
Whilst your number is being transferred, use up any airtime credits you have with your current network. You can also start using your Tesco Mobile SIM card to make and receive calls using the temporary number.
