Since for a traveller on a short visit this may be a real nuisance, such travellers would do well to be a little more careful. The powers supply is normally reliable. Brief power cuts do happen but are rare events. Adaptor plugs are readily available. The Botswana telecommunications network is modern and reliable.
Cell phones are ubiquitous.
You may sometimes have difficulty getting an international line at busy times. Driving Botswana, along with the rest of the region, drives on the left. The main roads are well-maintained. There are however problems of safety. Speeds are high, and as the main road between Gaborone and Francistown has only one lane in each direction, a lot of overtaking takes place, not necessarily in sensible circumstances.
