How to keep your number active
To stop your Pay as you go number being disconnected, you need to use it once every 180 days.
This must be for a chargeable activity – like sending a text or making a call.
If you don't use your phone for 90 days, we'll send you a text to remind you. If there's still no activity after the full 180 days, your mobile number will be disconnected and will not work again.
