Probably all comes at a cost.. sometimes hidden costs. You might find cheap electricity in relatively underdeveloped countries for example, but the infrastructure won't quite be there to support the rest of your operation (or crime might make that difficult).
Or in a super first world scenario, cheap electricity might be available, but rental etc. are through the roof
They must have access to the internet but I guess most people do these days, even with just a few dollars it is possible to have a low end second hand mobile...
