Mozambique telephones generally work and are modestly priced. At month end, however, it can become impossible to make a call to Maputo or beyond due to exchange overload. Cellphone services (Mcell and Vodafone) are now operative. Teledata.mz provides a usable internet service, but is prone to unexpected down time, sometimes for several days. Electricity is 220 volt by way of two-prong European plugs. Power lines come direct from Cahora Bassa. Power is nowdays fairly reliable, but unexpected outages for a day or more still do occur, as do breaks in the water supply. A major curse is voltage fluctuation.
