2D number on a sim i have had just after went live running a Nokia 6085.
i can make a call any time and it will go live for a bit, go out of range or not use it for a hour or so and voice mail here we go.
i have good coverage and it goes to voice mail, a mate that has ported from Telecom to 2D gets the same.
help desk had some good advice LOL turn the phone off then back on and it should work. only thing is after a hour in full coverage you can call the phone and hello voice mail........
is there any way to fix it? i was looking at pay monthly but i will move if i cant get this fixed.
