nepal telecom provides a CDMA cell phone service called sky phone. it has better coverage than GSM cell phone provided by the telecom. if the place you'll be working has sky phone coverage, you can use the SIM (also called RUIM) card to access internet. i'm not sure about the speed though becaue i've never used it but one of my friends did and it worked for him pretty well except in really rainy/cloudy days. maybe your uncle is talking about the same thing.
