Your new sim rollout isn't working.
New sims 'invalid'. Mine on Nokia 130 not valid on insertion, I can still use old sim for now. My partners on Nokia 215 worked for a week now Sim invalid, old sim doesn't work leaving her with no phone.
She is a carer. the phone is for work.
There seems to be a lot of this problem on the forum. Please advise urgently....
