Many customers of O2 have been taking advantage of an offer to surf the internet for free over a GPRS connection. Earlier this year O2 withdrew the offer and started charging for the service.
Although O2 sent text messages to all its customers informing them that the offer has ended some apparently did not receive the message and have been left with telephone bills of up to £1000. Customers believe that important announcements like this should be made by post as well as text message and there should be a warning system in place to detect users who are running up large bills.
O2 were under fire recently over another accouncement (again sent by text message) to turn off a large number of old mobile phones.
