Network! Best Choice is a software for your Windows device with a cellular modem which allows you to access always the best receivable mobile network at your location – regardless of your own provider. The prerequisite for this is a SIM card (not part of the delivery) that is able to log into the networks of the various mobile phone providers in Germany (national roaming). The software always tries to choose the best network technology (if there is 5G the software chooses 5G, if there is only 4G then 4G, etc.). If there are several providers providing the same network technology at your location the software automatically chooses home network of the SIM card. If the home network does not offer the best network technology the software selects an alternative provider with the best network technology.
