Have used T-Mobile internet for three months last year on East coast, and since Jan 1st now coming from NJ to CA and wandering around West coast. We have cable to one cell phone. As long as we get one bar of connection, internet works. Yes, it is slow, but it works. All cell phone connections are slow. New EDGE connection is faster, but costs more. We have T-Mobile for talking, so adding internet using one ofour two phones costs $20 per month, unlimited. We can add unlimited hotspot usage for $10 per month. This would use the built in WIFI when we go to a T-Mobile hotspot, such as Starbucks or Borders Books.
