Contact Lebara Mobile customer support on 0870 0755588 (5588 from your Lebara Mobile or +442070310791 from overseas) for a PAC (Porting Authorisation Code) before you cancel your service with LebaraMobile.
Once you have received your Port Authorization Code from Lebara Mobile, look for the best O2 offer that is suited to you. Many of the best mobile phone deals are available exclusively online, directly from the network providers listed here.
Finally, provide your PAC code to your new O2 mobile network operator who will then be able to port your existing phone number from Lebara Mobile. They will tell you what day the transfer is due to take place (usually within 48 hours).
Important: Do NOT cancel your contract before switching, otherwise you might not be able to port over your number. Once you provide your new network provider with your PAC code, your old account will automatically be cancelled when the number is migrated over.
Note: Credit on a PAYG (Pay-As-You-Go) account cannot be transferred and any remaining credit will be lost after the switch over.
The first step is to join O2.
Once you have done that, ensure you have the following information ready:
Contact O2 customer services and ask to transfer your old number. You can reach them either from your 02 mobile phone on 4445 for Pay & Go, or 202 for Pay Monthly contracts. Or you can call from a landline on 0844 809 0202 for Pay Monthly Customer Service or 0844 8090222 for Pay & Go Customer Service.
Alternatively, you can fill in the online O2 form and they will contact you when the transfer is complete.
Note: You may lose network service for a short period on the day of transfer. If this happens, turn your phone off and on occasionally, until you see the O2 signal on your mobile phone screen. This will indicate that the transfer is complete.
