What else can I say, its just works!!!!! I have been waiting for this solution to my poor AT&T service for over a year. So when I got word it was available, I ran out and dropped the $150.00. I really love my IPhone, but the service from AT&T was just crap; and this was a good solution.
It was simple to hook-up, just un-boxed; plugged into my router and after registering it on the AT&T portal, it was up and running in 15 minutes. After making about dozen calls; no quality issues or disconnects.
Personally, I believe AT&T should provide these devices for FREE to all people who are complaining about service coverage. Having good service will drive up minutes used, and I don’t see AT&T losing as we use more services.
