Joining Lycamobile from another network and keeping your number

Joining Lycamobile and transferring your number from your current network 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 your current network and handing it to Lycamobile.

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

1. Request a PAC Code from your current network

Switching from your current working and joining Lycamobile is easy. There is no need to commit a new number to memory or update all your contacts!

Requesting a PAC (Porting Authorisation Code) from your current network is easy here is how:

• Text: From your current phone, text "PAC" to 65075. You will receive a text back with your code within 60 seconds. 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.

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

If you would like a new mobile number and don't need to keep your current number, then request a STAC code by texting "STAC" to 75075 from your current phone. This is a universal number set up by Ofcom.
