This is not a critism, I only wanted to look up the coverage issues, especially in California, where Steve and I operate. I am including as attachments, diagrams of the coverage areas for Sprint, AT&T and CellularOne.
This shows Sprint as having minimal coverage in California, while the other companies have 90% of the state covered. This probably the main reason my cell phone bill is the highest in the company.
I should point out that CellularOne is (I believe) an analogue only company so I would have to pay roaming charges. AT&T's coverage while extensive, is a combination of digital PCS and analogue cellular.
