This is one of the best device I have ever used, this provides user to access high speed 4G internet even on 3G Phones
it is a portable hostpot, I have one of this device, I can make voice calls through this device.
it has 150M wifi and the speed which this device actually suppose to provide is around 150MBps but it only provide me around 15 to 20 MBps which is not ok. they must provide me full internet speed and by the way it really has cool battery back up. its wifi covers around 2-3 rooms which is great and even in some areas where phones not getting signals this device get enough signals to make a call.
Overall device is great but the only thing is with their Internet speed, they claim to provide 150mbps but only getting 20mbps
