Then the providers that do offer either a premium number text bar, or a total outgoing/incoming SMS block on my number are the ones I will be speaking to. If one can do it without affecting the GSM , then (other than for their own financial gains), there are no sound reasons why the rest cannot do the same.
Text messaging is nothing to do with GPRS. SMS uses the control channels which set up a voice call. Its just not possible to completely disable SMS without making the change for everyone in your area or disabling calls. By all means choose a provider that operates a blacklist, but be aware there are good reasons for and against doing it.
I can't believe that people are still having problems with premium rate text messages. In 2006 I had a problem with my 02 contract which reckoned that I had been using premium rate text servicing. I was allegedly receiving text messages every 30 seconds of the day and night at a cost of £1.50 a time. I alerted 02 who did absolutely nothing about this. They did not give me any advise but were happy to take a share of £2,760 pounds bill which ran up. I had thought this problem was resolved only to find out I have been passed to a debt collector. At the time I advised 02 these calls were fraudulent and not to pay the service provider to be advised "they already had". I think it is a disgrace that 02 are getting away with this and will now be taking things through the proper channels, after getting free advice from the Citizen's Advice Bureaux! :robotindifferent:
As i was alerted to a new message on this thread, I thought I'd reply. msb01 you have my full sympathy. My issue was nowhere near as frightening as yours and I wish you success. At least I have resolved my issue with O2. I have sinced ported my number to a new provider who were only too pleased to put the requested SMS blocks in place that O2 could/would not, I have not received one single SMS since the switchover. I have two phones on the same network, one(my phone) with the SMS block my wife's without, the statement Its just not possible to completely disable SMS without making the change for everyone in your area or disabling calls.has been proven to be incorrect.
After many years both as a BT then O2 customer I started to receive marketing messages from O2. After a while I got so fed up with them I sent STOP to the number stated. I received one more message then no more until about 6 months later and now they've started again. It cost me at least £1.50 to stop the messages the first time and I'm damned if I'm going to pay to have them stopped again. The only way that they tell you to get the messages stopped is to send STOP to them (at your cost). Personally, I give these people one chance to get it right, after that it is reported to the regulator. Ofcom, here I come. (not that they'll do much)
