hi

My wife and I both have personal mobiles that we have not used for some time. Not sure how long for.

We have separate mobiles for business which we use all the time and are on a BT contract.

On our personal phones we are both on T Mobile Pay As You Go. I was out walking today and needed to ring my wife and used the personal mobile (Nokia), only to find that it displayed " SIM CARD NOT REGISTERED". This was repeated each time I tried to use the phone.
I know that I had about £40 on the card.

When I got home I charged the phone but the same thing happened. I checked my wife's phone Motorola and the same thing happened -slightly different wording. She has about £25 on hers.

Has anybody any ideas what has happened and what we can do about it??

Cheers
