Service and support is more important in M-Commerce than traditional business. The strength of M-Commerce is based on four factors: the anticipated ubiquity of devices, online access for a large portion of the world’s population, location sensitivity of the devices and authentication and authorization capabilities (John etal. 2008) [22]. Different generations of mobile (1G, 2G, and 3G, 4G) play an important role in development and expansion of M-Commerce. These generations varies with their speed of data transmission. Research is going on to make a seamless gaming between 2.5G, 3G and WLAN so that mobile device will detect the network with higher bandwidth and switched to it. The handover will occur without interrupting existing connections, and then WLAN can be used as complementary technology of M-commerce [EITO] [23].
