Mobilna Telefonia Internetowa Sp. z o.o. (MTI) is a new operator on Poland's mobile telephony market, offering its LoVo service based on internet telephony (VoIP) via cellular phone with broadband internet access in WiFi and/or UMTS technology.

MTI offers fully functional mobile telephony in the Unlicensed Mobile Access (UMA) technology. The company is not connected to any other cellular telephony operator. So far, the pioneering UMA technology required cooperation with a specific GSM network that offered such services. The MTI service makes it possible to use the services of any GSM operator. The UMA function allows for switching calls between the VoIP and GSM networks. When the user of a mobile phone with the LoVo application gets out of wireless internet range, they are automatically switched to the GSM network.

MTI's LoVo service is the first such service on the Polish market that offers smooth roaming between WiFi and 3G third-generation mobile networks. If the quality or strength of the WiFi signal falls during a call, the system switches to the UMTS in a way that is imperceptible to the user.

The implementation of advanced technologies on the LoVo platform is the result of two years of cooperation between MTI (formerly Echotel) and its Irish-owned partner Netgear Poland, a provider of wireless network infrastructure. MTI is the sole user of the LoVo system on both the Polish market and in all of Central Europe.
