Reinstating deactivated phone number

[tpj500]

Hello! My phone number was deactivated a few days ago for lack of activity (I've been abroad), and I'd like it back if possible as I've had it for 10 years. Is it possible to reinstate it?

PAYG numbers have to have a chargeable action every 180 days or the number is lost and cannot be retrieved.
