It sees a 3G tower when I manually check towers, but it won't connect to that. It will only connect to 2G :/
To be honest, we're still learning about how the technicalities of coverage work. The devices can definitely work on HDSPA + up to 21Mbps, but how it determines which signal/frequency to lock onto - we'll need to do some more homework. In general though people seem to be good speeds.
It's also not a good idea to compare phones with your MiFi. A smartphone can work on a much broader range of frequencies, etc so results will differ to the MiFi
