I did the 15-day "FREE" trial with Alltel's USB broadband service. It worked well going down the road. Unfortunately, it didn't work well inside my house. So I returned it 10 days later and it ended up costing my about $25. So much for a free trial. They said I had to pay for the days I used it. To top it off, I keep getting a bill from them every month that I have to go into their store to get straightened out. This has happened for 3 months straight. I digress...
