I was looking to have an internet connection on my holiday place where my phone was usually not much 3G reception. (Thus sharing feature useless internet). After having inserted my SIM card (that of my phone) into the router, 3G signal was much better and I could have captured found the optimal location. We connect in wifi 4 devices simultaneously, proper speed internet (careful, do no miracle on the premises without cover). Also used by car on the highway, nickel. Main features to note: - No installation / parametrage necessary: a lighting simply connect wifi and launch the admin interface via the browser of the tablet eg. - Ability to view / write sms - Ability to disable entering the pin of the SIM card to the WIFI (very handy as must be done via the web interface every time otherwise) - Monitoring the conso data (useful for limited packages) - SIM adapters - Good battery life - Very compact (for a handbag ;-) - Downside: SIM not very practical to remove it (you almost drive a nail or very thin object to reach it) But I highly recommend!
