I leave my phone on 24/7, and it seems more and more of my calls have been going straight to voicemail without my phone ringing. I'll get the voicemail notification a minute later, but this is annoying because I know some of my friends don't leave messages (cause sometimes I'll get a missed call, with no voicemail). At first, this was mainly happening to me on Friday afternoons, when I guessed that the network was being taxed pretty heavily. But this also happend to me twice last night, Saturday at 10:30, and at 1 am. I wonder if that was because I was in a weaker service area (inside buildings) or because the network was busy? I'm with Cingular in Dallas; both times I was deep in metropolitan Dallas, well within the service area. This is my first disappointement with their service so far. A while back I asked Dukedog why Cingular didn't offer more minutes on their home plans - for instance, Verizon now offers 900 anytime + unlimited n+w in Dallas, for $45/month, where I only get 400 anytime for $40/month with Cingular. His answer was that Cingular has a lot of customers, and if they increased the amount of minutes, the service would not be as good. Now I'm starting to wonder if it is already too many customers.
