We have never worried about cell phone coverage overseas. Now, at least for Africa due to driving over open country, we are looking at wanting to have a cell phone. It might also be good for trip to Asia.

We have ATT Wireless which has switched to Cingular. We have cheap nokia phones that are almost two years old. Does anyone have ATT/Cingular experience with trying to use/modify for overseas use? Should we just get new phones? Should we just rent a phone in Africa?

thanks,
