Without question, San Diego is one of the more difficult regions for decent cellular coverage. AT&T finally offers 3G MicroCells to customers with little or nonexistent service to their homes and offices. I got mine this morning, and it works GREAT!!! Full bars of coverage and appears to provide faster data downloads. $150 with $100 mail-in rebate. Although the MicroCell connects to and uses your home or business internet connection, AT&T still counts the calls and data usage via your own internet access against your phone plan minutes. However, you can sign up for a $20 monthly unlimited MicroCell plan.
