I have several months using this device
I have several months using this device, and working really good.
I using this device for fowarding my calls when i'm outside the office, and for using voip calls on the road, and avoid long distance rates.
I have two MV-370, one Quadband and another triband. The quadband not working good, Portech recomend use triband is that is possible. The quadband have some problems with firmwares and the GSM networks.
Be carefully if you buy this device from ebay from an user called eugene or something like that, in two times i brought something at this user, the device not working, i suggest buy directly from portech, they offer a service really good.
