At & t 3G Microcell. Used, in perfect condition, works wonderful. This links to your dsl or cable television internet and works as a mobile phone tower, for people who have bad AT&T mobile phone reception at their house. We moved and have terrific reception now, and I not need it. These are over $200 from AT&T new. When we utilized it, we had 5 bars of service anywhere in our house, and anywhere within our 2 acre yard. We stayed in a really backwoods and had no service for 3-4 miles without the microcell. I travel the entire eastern half of the state for work, so I can probably bring it to you, if youre not near me. Call or text whenever. Thanks.
