I have a few questions of how roaming works with Sprint. Heres what happened...... I made a call in my basement that was on digital roam... I kept talking until I arrived at the store, which has a great sprint signal. i pressed a button to light the screen so i could see if I was still in digital roam, and i was. from the time i went out of my basement i would have had a sprint signal. is it normal for the phone to stay in whatever mode it is until you finish the call for ex: if you make a call in digital roam will it stay in digital roam until you finish the call even if you would have a full sprint signal? also, if you are driving and you loose your sprint signal can your phone go into roaming without disconnecting the call? i was driving and talking on sprints network when i lost my signal because of going down hill, but the signal came back about 2 sec later so it didnt ever go into digital roam. one last thing.... many people talk about how they were roaming on verizon, alltel or w/e other provider, but how can you tell? im 99% sure that I digital roam on verizon around here, because its the only CDMA provider i know of other than sprint that has service here. this is kind of off the sprint topic, but i have heard that gsm phones will switch to roaming without any problems .. is this true?
