Default Missing Phone Calls While Using Apps?

Please Login to Remove!

On my 7250 with VZ Wireless when I'm using midpssh, idokorro or maybe even the web browser, my calls go right to voicemail. It was doing this to me earlier and then I had to quit the programs so I could get calls again. Is this normal?

Unfortunately yes with CDMA device. With CDMA devices, data will not be interupted by a phone call so the calls go right VM. With GSM/GPRS device like T-mobile and Cingular, your data will get interupted when a phone call comes in. Quite frankly I find this a problem with CDMA blackberries and won't use one for that reason alone. Phone calls are always more important than emails or data transmissions to me.

Wirelessly posted (7250: BlackBerry7250/4.0.0 Profile/MIDP-2.0 Configuration/CLDC-1.1)

This has been discussed at length before....

The issue of missed calls while data is being transferred occurs on both GPRS and CDMA devices--that is any device that can handle voice and data.

CDMA is slower to suspend the data session than GPRS, thus the perception that this condition is exclusive to CDMA.

The issue will only occur if the call comes in while data is moving. Since wireless data is bursty, it doesn't occur too often.

You can be on a data application and your handheld not be transmitting data, which explains how you can be browsing and receive a call. But if your BB is in the process of a data transmit/receive (you'll know because the transmit/receive arrows will be active) you will not receive a call and vice versa.

This is correct.

On GSM devices, your calls go to voicemail whenever there's "data transfer" going on. Such as in the middle of loading page. However, if the call comes in while you're between webpages (no further data), it will come through. Basically, it's as if the data connection immediately connects/disconnects after every packet. (Zero overhead to switch between voice and data mode)

On CDMA devices, because of the way CDMA data work (lots of overhead to switch between voice and data mode), the data connection will idle for some time for efficiency's sake. So that means, for XX number of seconds after you finish loading data in a third party application, your calls will not come through until the device has idled long enough after the last packet (timeout).
