You need to make a chargeable call at lease once every 6 months and top up every 999 days.

You would lose your number unless you do the above as it's recycled. If you go a month over that 6 months you could get the number back but you would need to call customer service who will reregister unless it's been reallocated to someone else.

This has happened to a friend a very low user was with a different phone company whilst ill, cut off took money left in too 👎 Actually the terms were much worse than O2 .
Changed to o2 after that.
Good luck take care TallTrees
