First I tried Huawei E5573Cs-609 and it didn't work, but this hotspot worked fine at AT&T in US. You can tell immediately that this is a quality product. I liked the on screen controls (nice clear display) rather than being tied to an HTML control. The reception is good. The battery life is really good, although the only reason I gave it 4 stars was because the device turns on automatically when charging (I didn't want it to reset data at night while charging).
