For you guys having signal problem, Just remember 2G,3G, and LTE are 3 different freq. So it other word is you can have full 3g signal and no 2g at all or the other way around. Full 2G but no 3G or LTE. Each signal is on its own so even if you have the greatest 2G signal in the world It will not give you 3G. (also weather pleases a role clear sky is better then a rainy cloudy day)
Some people think its a stepup signal that if you have full 2g then you will get 3g but that is not true. Also 3g can shrink when more people use the tower. So sometimes you might have better signal during the night and bad signal during the day.
I also recommend getting a 5m usb cable (not the cheapies) and stick your modem out the window. This may improve your signal from 0 to full. 3G don't really go that great thru walls. In my house I have no 3g inside but full in the window.
I went outside and put it away from all the walls and still no improvement. Will trial tonight by driving around in the area and seeing what happens.
Mine's still marked as "En Route" so I don't see any of that shizzness.
