What is the process for changing mobile provider?
To take your number with you when you change companies, first contact your current mobile provider and tell them you want to leave.
Tell them you want to take your mobile number(s) with you and ask for a Porting Authorisation Code or PAC. It must be issued to you immediately over the phone or within two hours by text message.
Your PAC is likely to be a nine digit code and is valid for 30 days. If it runs out, you will need to request a new PAC from your existing mobile provider.
You should then contact your new mobile provider and give them your PAC.
Once your new provider has your PAC and notifies your existing provider of the port request, your number will normally be transferred the next working day.
Some mobile phone providers may charge you a fee to move your number. You must also remember that, if you are still under contract to your old company, you may still be liable for charges under that contract.
