WiFi phones have a great potential because they allow you to make cheap or free calls while you are on the move. This is why they have become highly popular in the short time they have been on the market.
What keeps WiFi phones from being accepted as a reliable means of communication at all times is the absence of a country-wide hotspot network like the cellular network.
However, a step in this direction is that many cities are developing city-wide WiFi networks and increasing number of cafes, airports and public places are providing the free or cheap hotspot facility.
Another development that should help WiFi phones gain wider acceptance is the recent introduction of Dual-Mode Phones (see box). With these phones you are assured of on-going connectivity while enjoying the benefits of WiFi phones when you are in the hotspot coverage area.
