Best Uses

    Comments about AT&T 3G Microcell:

    Put this microcell in my basement with computer and get a strong signal all over the house. I went from 1-2 bars signal strength to 4-5 bars. It is recommended to place the microcell next to a window but I was unabel to do so. It still worked great. My only regret is that I didn't buy it sooner.

    Service and delivery comments:

    My order arrived promptly and in good condition. Would order from Abt again.
