Try calling Digi @ 016-2211 800, ask them to either extend rings or cancel off your voicemail.

Couple of forumers here confirm it work on TOUR.

I also got a confirmation from digi_telco from their twitter reply

Hmmm ... do they offer Bold? I thought only 8520? or you took the Business one? I want the 8900 though... 

Hi techgirl, my Digi smart plan is having the same behavior as well.  I don't perform tethering or connect to PC at all. 

I guess Digi Customer Support still new with Blackberry service, thus I received pretty different information whenever I call them.

a)  First called and asked about the unbilled amount, CS1 said, no extra charges on internet usage, as long as I am using the Blackberry device. However, they can not see my unbilled bill until the bill is out. But said it should be able to waive it once I call back when I received my bill. 

b) When bill is out, amount is RM52.90 for GPRS, which minus some unexplainable charges rebate for Blackberry RM 9.67 and DATA PAYU Tier 1 RM4.58, so all in all I am still need to pay additional RM38.65 for GPRS.  Which after a call to CS, they said again they will try to waive it.

c)  Recently, notice again the unbilled transaction is on the rise although i seldom make calls.  Call back Digi CS, same reply as (a)

d)  Tried D'chat instead, the CS2 said nothing need to be configured on the Blackberry, it should be automaticly configured.  But later when I asked about the APN settings, this round the CS replied APN should be set as "blackberry.net".  When I asked what is the different if I don't set it, he takes about 4 minutes to ask me to wait and say he will escalate it for further clarifications. 

I am pretty happy with the Blackberry service overall but looks like subscriber like us may need to "escalate" this issue if persist.  At least help Digi to firm up their configuration needed on Blackberry to avoid unnecessary charges to subscriber.  If this issue persisted, it rather looks like Digi is cheating consumer money by tricks(no informing customer on correct configuration).  Paying BB services but still get to pay additional GPRS.
