I am updating my my seminar for DSC this year and I need info on what if anything has changed as far as clients and cell phone use and service while in camp. I have previously talked about clients renting phones at the airport for calls back to the US I have also talked about sat phones, and getting sim cards from their own US carrier. What do you see today as the best options for clients to get cell phone service in camp? What do they seem to be using now? Thanks for any help guys!
