What are dual band phones that can least cost route using GSM or Wi-Fi?

Answer 1

This means phones that are both GSM cellular and Wi-Fi can be used to make calls on cell phone network and also use the Wireless Internet to make outgoing calls on Wi Fi hotspots (such as hotels, restaurants, airports, coffeeshops, and certain cities) which of course will be cheaper and sometimes free compared to the cost of what your cell phone provider charges. At the moment, Wi-Fi built in is still a brand new feature in most cell phones. Soon or later T-Mobile will be the first cell phone carrier to have a cell phone plan and also a Wi-Fi plan so that you will make outgoing calls cheaper using both types of network.
