Mozillion PAC Code: keep your number and switch networks

Joining Mozillion from another network and keeping your number

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

You can usually give Mozillion 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 Mozillion.

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 Mozillion

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

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

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

3. Give the PAC code to Mozillion

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

• Online: Enter your PAC code at checkout when you order, or log in at mozillion.com/login, go to Edit My Plan in your Dashboard and request your number transfer there.
• Phone: Call Mozillion on 020 3893 8441 and give them your PAC code.
• Email: Email help@mozillion.com with your PAC code and the number you are transferring.

4. Wait for your number transfer to Mozillion to complete

Mozillion will send the transfer request to your current network.

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

Leaving Mozillion: transfer and switch your Mozillion number to a different network

To leave Mozillion and keep your number, request a PAC code from Mozillion 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 Mozillion

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

• Text: Text "PAC" to 65075 from your Mozillion phone. You will get a text back with your code within a minute. This is a free service from Ofcom (the UK's communications regulator).

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:

• Online: When you order your new SIM card online, you can enter your PAC code.
• 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 Mozillion.

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

4. Wait for your number transfer to your network to complete

Your new network will send the transfer request to Mozillion.

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