Tesco Mobile PAC Code: keep your number and switch networks

Joining Tesco Mobile from another network and keeping your number

To keep your number, request a PAC code from your current network and give it to Tesco Mobile.

You can usually give Tesco Mobile your PAC code when you order, or after your new SIM card or eSIM has been activated.

1. Request a PAC Code from your current network

You do not need to change your number when you join Tesco Mobile.

Request a PAC (Porting Authorisation Code) from your current network using one of these methods:

• Text: From your current phone, text "PAC" to 65075. You will receive a text back with your code within a minute. This is a free service from Ofcom (the UK's communications regulator).
• Online: Some networks will allow you to log in to your current online account and request your PAC code.
• Phone: Call your current provider's customer service phone number from your current phone.

Requesting a PAC does not cancel anything. Your current plan carries on as normal until the code is used, and if you never use it, it simply expires after 30 days.

The text with your PAC will also show any early exit fees you would pay or credit you would lose by switching, so check it before you hand the code over.

2. Order a SIM only deal from Tesco Mobile

If you have not ordered yet, compare current Tesco Mobile SIM only deals below.

If you already have your new SIM, continue to Step 3.

If Tesco Mobile asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give Tesco Mobile the PAC code using the method below.

3. Give the PAC code to Tesco Mobile

Once you have your PAC code, here is how to give it to Tesco Mobile:

• Text: Text "Port" to 23424 from your Tesco Mobile SIM and follow the instructions that come back by text.
• Online: Use the web chat on Tesco Mobile's website to hand over your PAC code.
• Phone: Call 4455 from your Tesco Mobile phone or 0345 301 4455 from any other phone.
• In-store: Visit a Tesco Mobile store and ask to switch your number to Tesco Mobile.

4. Wait for your number transfer to Tesco Mobile to complete

Tesco Mobile will send the transfer request to your current network.

Your number should move to your new Tesco Mobile SIM within 1 to 2 working days.

Leaving Tesco Mobile: transfer and switch your Tesco Mobile number to a different network

To leave Tesco Mobile and keep your number, request a PAC code from Tesco Mobile and give it to your new network.

You can usually give your new network the PAC code when you order, or after your new SIM card or eSIM has been activated.

1. Request a PAC Code from Tesco Mobile

Here is how to get your PAC (Porting Authorisation Code) from Tesco Mobile:

2. Order a SIM only deal

If your new network asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give your new network the PAC code using its transfer process.

3. Give the PAC code to your new network

Once you have your PAC code, here is how to give it to your network:

• Phone: Call your new network's customer service number and provide them with your PAC code.
• In-store: If your new network has a store you can visit a store, and a staff member will help you transfer your number using your PAC code.

Your new network will handle the transfer. Give them your PAC code within 30 days of receiving it — after that it expires and you will need to request a new one from Tesco Mobile.

If you want a new number instead, text STAC to 75075 and give the code to your new network.

Your new network will send the transfer request to Tesco Mobile.

Your Tesco Mobile number should move to your new SIM within 1 to 2 working days.
