Works great with good SFR settings

Very effective, the camera captures the best network (4G or not) my phone Xperia Z3C yet sensitive.
SFR subscriber 4G, I had to correct APN parameters given by default.
APN: SFR (but whatever), APN: websfr (not sl2sfr), username and password: not informed, authentication: none / none, PDP: IPV4, PDP roaming: IPV4 (I 5GB in Europe ...)
All this is done by the aircard application (downloaded from the store) or web browser (eg 192.168.1.1 or netgear.aircard, Passepartout default password: password)
