Although there’s already legislation in place meant to prevent scams and unwanted calls, many carriers aren’t doing enough to protect their customers from unwanted robocalls.
For example, Verizon ranks 11 in a chart of 14 US phone companies when it comes to robocall protections. What’s worse is that half of these companies earn D or F grades regarding these protection services.
Verizon scores an F in Services and a D Overall, and while T-Mobile is doing a little better (C in Services and B Overall), it’s incredible that some of the biggest carriers in the United States aren’t concerned about the safety of their customers.
The big surprise is AT&T, which scored A in Services and B Overall. The US carrier is ranked 3 in the top, but the other two spots at the top are even bigger surprises.

Comcast Xfinity is ranked 2 in the report from the Public Interest Research Group, with a score of A in Services and A Overall. The top-ranking US carrier when it comes to robocalls protection is Spectrum, the country’s fastest mobile provider, now serving more than 10 million customers.
Of the companies that the Public Interest Research Group surveyed:
- Five companies scored an A on Services offered, three scored an A Overall.
- Two companies scored B on Services offered, five scored B Overall.
- 12 earned D or F on Services, and 13 earned D or F Overall.
Here are the Overall grades for the big four US carriers: AT&T and T-Mobile scored B, U.S. Cellular scored a C and Verizon scored a D.
