Esther Shein:
In an all-time worst rating for a carrier ever recorded by ChangeWave, the research firm said AT&T subscribers reported that about 4.5% of their calls were dropped over the previous three months.
Coming in second for the period was Sprint, whose users reported 2.4% dropped calls and T-Mobile customers, who reported a dropped-call rate of 2.8%, was third. Verizon Wireless customers reported the least amount of dropped calls at 1.5 percent, the lowest ever recorded in the survey.
I can vouch for that.
