Consumer Reports has ranked Verizon the best U.S. Carrier and AT&T the worst based on the results of a recent poll conducted by the company of more than 66,000 subscribers about their phone service.

This is AT&T's second year at the bottom of the heap. Verizon was closely followed in the survey by Sprint, with T-Mobile taking third place. Verizon was able to take top honors for its staff knowledge, as well as the quality of its texting and data service.

"Our survey indicates that subscribers to prepaid and smaller standard-service providers are happiest overall with their cell-phone service," said Paul Reynolds, electronics editor for Consumer Reports. "However, these carriers aren't for everyone. Some are only regional, and prepaid carriers tend to offer few or no smart phones.The major carriers are still leading options for many consumers, and we found they ranged widely in how well they satisfied their customers."
