Cell Broadcast Adverts available now. (Score 1)

I searched the comments and no one seems to have mentioned this yet, so I hope this is relevant. But adveristment/information through mobile phones based on your location (known via the closest cell broadcast) is already done in some countries like Hong Kong. Instead of displaying your location (eg POST CODE is UK) it sometimes displays special discounts in the area. If it's short enough you can just scroll it, or sometimes you have to phone a free code (eg #88) to get more info. The scenario is similar to the comment below.
