No, honestly, it has. Unsurprisingly, BT informs those that ask that the rocketing use of mobiles has slashed income from public call boxes.
Mobiles being mobile is also an advantage.
Mobile phones may be getting lighter, but they can still be heavy on the pocket. So say the new ads. And they're right. Perhaps this is why BT doubled the minimum charge of public call boxes a couple of months ago from 10p to 20p - to try to keep it in line with mobiles. We can see the campaign being a great success.
