Hiya.
Probably of no interest to most of you, but I thought I would mention this.
My daughter (13 yrs, and don't we know it !!!) was racking up a Sizeable mobile phone bill (actually my phone, paid for by my business), so I googled call blocking so that she couldn't overrun her call allowance.
The googles said it wasn't possible to block, but I phoned Orange and explained. They said all I had to do was to keep track of how many minutes she had left and if she did get near the limit, call orange and they would block outgoing services.
This would also block outgoing text messages.
I put a block on the phone for an hour, which madam didn't like one bit

The point was made though and normal service was resumed shortly afterwards.
She has agreed to go easy when I advise her she is near the limit.
Yep, she is lazy.
Regards.
