O2 to O2 but with a new provider - how do I keep my number

[em9]

Hi there,

My handset and airtime contract have both expired with O2, I'm now just rolling on paying for airtime on a monthly basis.

I've bought a new handset and signed up for a new O2 contract with Mobiles.co.uk. Will my current phone number migrate automatically or do I have to do something to make sure my current phone number stays with me?

I've read loads of FAQs but they all relate to leaving one network and moving to another - it's almost like I am trying to do something which is impossible but in reality must happen all the time. 

Any help appreciated. Thank you.

Your old contract will continue until you call customer service and ask them to migrate your number to the new contract.

This will then end the old one.

Pefect, thank you. I will ask them to migrate the number then rather than port it.

Yes, that's it @em9

Have done this a few times.
As advised, call customer services and give them the details.
Please be patient as they are really busy at the minute, and there are lots of people reporting issues transferring numbers so there may also be a delay there.
