You can keep your existing mobile phone number from your current pay as you go or contract phone when purchasing a new mobile package from Phones4.co.uk depending on which network you want to transfer to. If you are unsure of your eligibility to port then please use our porting guide.

We currently only support number porting when transferring to T-mobile, Orange, Three, Virgin and BT Mobile, but not Vodafone or O2.

To keep your existing mobile phone number all you need to do is follow these simple steps:

1) Place your order on our website

2) Contact your existing network provider to request your PAC (Porting Authorisation Code)

3) Contact your new network provider on the appropriate number below and quote your temporary number (the number your new phone is registered to), your existing number that you want to keep and the PAC.

You can keep your existing mobile phone number from your current pay as you go or contract phone when purchasing a new mobile package from ANY Phones 4u store.

All you need to do is follow these simple steps:

1. Request your PAC number from your existing Network or Service Provider

2. Take this PAC with you when you go into store

3. Once you have selected the handset and network tariff, inform the member of staff that you wish to port your number and give them your PAC

4. The member of staff will use this PAC number when processing your sale and will inform your new Network that you wish to Port your number and provide them with your PAC number

5. Porting your number will take approximately 5-7 working days. Your network should inform you once the transfer has been completed.

We are currently developing the porting functionality for O2 and Vodafone. In the meantime, if you want to switch to O2 or Vodafone network and still keep your old mobile number, we suggest you visit your local Phones4u store, which will be able to help you with your request.

Do not cancel your existing contract, as disconnected numbers cannot subsequently be transferred. By providing your PAC number to your new chosen network this will initiate the cancellation process with your current network.

To port your number there may be a small administration charge from your current network and we advise you to check this one out first.

When porting your number to 3, it is important to be aware that once the transfer has taken place, both your existing ported number and the new mobile number supplied with the phone will work on your new handset. To receive video calls you will need to supply your new 3 number to people wishing to call you, as video calling will not work via your Ported existing number.
