We live in the mountains in Andalucía, Spain without any cellphone coverage at all, either in the house or on the terrace. It was really impossible to contact with someone by phone and all that complicated our life a lot. However, I found that I had a 2-3 bar signal on the roof of the house (one level bungalow). That signal probably went from a base station but of course was too low to catch it by a cell phone. I was really frustrated until I found a solution. With the AT700, we now have 5 bar coverage throughout the house and 3-4 bar coverage on the swimming pool terrace. The results of installing the AT700 have been both surprising and outstanding.
I have already recommended cell phone booster to other people with the same problem. Trust me, if you live in a zone with a very low signal (like in the mountains, for example) this is an easy solution! I was actually very surprised when I was able to install the AT700 by myself. It’s also very easy to use.
