5810 Voicestream & Cingular

[fgonzalez]

I currently use a 957M with cingular. I also have a GSM phone with Voicestream. Does anybody know whether I can integrate both using a 5810? In other words, can I use voicestream for phone functions and cingular for data?

Nope - with a 5810 both services go with a single carrier. Cingular handles data over their Mobitex network. VoiceStream handles voice over their GSM network and the data over the GPRS network which rides on top of GSM.
