Joining Asda Mobile and leaving Smarty

Joining Asda Mobile and transferring your number from Smarty is a simple process and usually takes no longer than 1-2 working days.

The process which will go through in more detail below involves requesting a PAC code from Smarty and handing it to Asda Mobile.

You can either hand the PAC code over to Asda Mobile during the ordering process or after you have received your new SIM card or eSIM has been activated.

1. Request a PAC code from Smarty

Switching from Smarty and keeping your current phone number is quick and easy! No memorising a new mobile phone and updating all your contacts is unnecessary.

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

• Text: Text "PAC" to 65075 from your Smarty Mobile phone. You will get a text with your code immediately. This is a free service from Ofcom (the UK's communications regulator).
• Online: Log in to your Smarty Mobile account online and navigate to "My Profile." Then, from the "Transferring your number" section, you can request a PAC code.
• Contact Customer Service: Contact their customer service through webchat or email to request your PAC code.

Your PAC code is valid for 30 days, so you can request it before you get your new SIM card.

If you want a new number and do not wish to keep your current number, you will need to request an STAC code instead of a PAC code. Text "STAC" to 75075 to get your STAC code.
