If the size of the data SMS exceeds (160 Characters * 7 (I believe each character is encoded using 7 bits), you have to split and send it? I tried receiving a data SMS in the emulator, (sending ...
I didn't really want to post here as there is so much information on the net, but I've trawled the depths and can't figure it out. Ok so I can't get this to work in two scenario's hopefully the answer is the same for both. My problem is I set the request header but it doesn't seem to send it.

The problem is that the number of stars doesn't seem to do anything at all. In portrait-layout I get 6 stars and when I flip the phone I get about 10 stars. I tried to set the number of stars in my Activ...
