I'm having the same issue as others. I ordered a BYOP sim, activated it, ported my number and got both telephone and text on my phone within an hour of activation. However, data is not working yet.
I have configured the APN on my phone, using both the APN Changer tool at http://www.unlockit.co.na
, and also manually with the Apple iPhone Configuration utility and the printed APN configuration settings provided with my SIM.
My phone says "you are not subscribed to cellular data service" whenever I try to use cellular data. The status bar on the phone shows "HOME 3G", which makes me think I have a data connection, just no data service.
HELP - how do I get data to work?
