Owner of a 3G iPad with a SIM card and use often in modem mode, I acquired this router to recycle my SIM card and to be able to connect my mobile devices. The router is very easy to use and knows to be forgotten at the bottom of a bag or pocket. Connect over different devices: iPad (Retina and mini), Mac, tablet Nexus ... No problem, it's all wifi is compatible. The web configuration interface mode is very simple.et the front pictograms provide information about the status of the router with a single glance. The transmission speed is good as long as the network is good. The function is sending and receiving SMS messages is nice, even if suddenly we begin to dream of a small LCD screen that would display without having to connect a machine. My only focus on the autonomy s limited to 4 hours. Fortunately recharging USB makes it simple to connect to his PC or MAC, also connected to a computer, the mounted hard drive and provides access to the driver that allows to use in USB modem mode as a key classic 3G. So very good product that never leaves me.
