I have been receiving messages on my iphone recently which takes up the whole screen, only with a dismiss button.
I have asked a question previously and realised it could be some sort of advertising by the telcos. Do anyone have the same experience too? Or there's known telco providers that send such stuff to users?
Another issue that I am quite in doubt is that the messages stated with the 'advertisments' are not advertising any products, just being irritating. Could it be some kind of 'ad-ware' instead?
