iPhone 3GS Missed Calls/Phone not ringing/Calls go to Voicemail despite full signal
Further to my post yesterday about the iPhone 3GS calls going to directly to voicemail without the phone ringing despite the phone showing a good signal I have now done some more testing myself to check how this works and why it might be happening. My findings are as follows: 1) If your iPhone is using an app that connects to the internet AND your phone is connected to 2g (o or E symbols) then all calls will go direct to voicemail for the duration of your connection to the web. Once you close the application then the phone will ring again. 2) You may have no knowledge of these calls happening unless the person leaves a message. The iPhone 3Gs does not show any record of the calls being received. 3) If your iPhone is using 3G then you can receive calls as well as using the internet at the same time. Despite this scenario being denied by O2 iPhone support who should know better (they claimed that a phone call will always interrupt a data call - my testing proves this is not the case) and lots of reports across the web show that EDGE/GPRS connections do not support voice and data at the same time.
