Can anyone explain why I cannot get an account  Call Plus SIM to work with a iTegno 3800 GPRS device? This issue to me appears related to account SIM cards as it will work on a Voda Prepaid SIM OK.

I also tried my Spark account SIM card also with no success. I have yet to try a Spark Prepaid, but I'm thinking there is some setting in the system present in account SIM cards that blocks no phone devices while prepaid are open.

Any thoughts?

Cheers

John
