I just received a Sierra Wireless Voq V11 Smartphone. Phone calls and SMS work great on it. I don't use data, so that isn't an issue. What I'm unable to do, however, is call any "Cingular" numbers. This includes Voicemail (+19802548962) and Customer Service (611). When I try to do so, I instantly get the generic 'invalid number' tone. What's strange is that the phone successfully downloaded the correct voicemail number AND alerts me that I have new voicemail waiting. I also am unable to dial my own number, probably because Cingular reroutes it to voicemail.
The same thing happens on two other known-working SIM cards in the phone. If I didn't know better, I'd say Cingular is blocking the device...can they even do that? Any ideas? Thanks!
