I have Alltels UPrepaid service I'm charged $1.00 a day for unlimited text, M 2 M, and Night and weekends, I also Pay $5.99 a month for mobile internet but if i call or use internet before 9Pm on weekdays im charged 10c a min. I am very surprised that they let me use a Data phone with prepaid. And now im tethering...... This is unbelivable!
