Smarty PAC Code: keep your number and switch networks

This guide explains how to switch to or from Smarty and keep your mobile number.

Most number transfers complete within 1 to 2 working days once your new network has your PAC code.

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

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

You can usually give Smarty 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 Smarty.

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 Smarty

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

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

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

Smarty does not run a credit check, so there is nothing to wait for during sign-up.

Smarty offers eSIMs, so switching to an eSIM plan can avoid waiting for a physical SIM to arrive.

3. Give the PAC code to Smarty

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

  • Online: Enter your PAC code at checkout when you order, or log in to your Smarty account and go to Menu, Account settings, Your phone number, then Enter my PAC or STAC code.
  • Webchat: Contact Smarty's customer service team through webchat to hand over your PAC code.

4. Wait for your number transfer to Smarty to complete

Smarty will send the transfer request to your current network.

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

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

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 Smarty.

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 Smarty.

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