International Favourites Call Me Number - how long do I keep it?

[Anonymous]

Hello,

If I sign up for an international favourites bolt on "call me number" and then at some point I wait more than a month to top up, will I have to get a new number when I come back to it?

In other words - I am on Pay&Go, sometimes I spend a few months at a time out of the UK during which time I don't use or top up my O2 sim. If I use a call me number, and then for a few months I am not topping up so the bolt on isn't paid for, will my call me number be held for me for when I top up again (and the bolt on/my sim is reactivated)?

Thanks for your help!

As far as I'm aware the call me number is unique to the sim and is retained as long as the sim remains active ie. a chargeable call is made every 6 months.
