Here's one view of some of the challenges of doing business in emerging markets. I quote form an internal email with names excised:
It turns out we heard from <…> last night. He is out in the "boonies" and does not have good communications. He called to get some guidance on a site that is having some issues. He has no LAN connection and limited to no cell coverage. He got to a land line to call. … he sounded exhausted. You can see his living quarters below. It seems he is driving by day and installing by night.
I love the vehicle! It’s rented from: http://www.voyagerszambia.com/safarivehicles.htm
Creative lodging, creative travel arrangements, little or no access to voice or data communications but at least this is a relatively safe area, compared to some.
