Phone companies say they finally have a way to block robocalls for good

America’s cell phone carriers are uniting to take a stand against robocalls.

Twelve of the biggest American phone companies, including AT&T, Sprint, T-Mobile, and Verizon, promised on Thursday to start using a new technology that can identify and block the pesky spam calls, according to the Washington Post. The carriers are partnering with 51 attorneys general and will announced the pledge in Washington. 

The Post reports that the new spam caller blocking technology is called STIR/SHAKEN and identifies spoofing practices that robocallers often use to make numbers appear as a local call. The new technology is expected to be implemented by all carriers “as soon as practical.” 

As part of the pledge, the carriers will also offer free anti-robocall tools to users. 

Aside from the big four, other carriers taking the pledge include Comcast, Bandwidth, Charter, Consolidated, U.S. Cellular, CenturyLink, Frontier, and Windstream. 

The Federal Communications Commission (FCC) voted in June to allow cell phone carriers to automatically block robocalls. The major carriers already have robocall blocking programs in place, but Thursday’s pledge is a serious step in making the prevention robocalls a major priority for all cell phone carriers. 

In June, the Federal Trade Commission (FTC) and law enforcement officials announced a strict crackdown that takes aim at U.S. companies responsible for over a billion spam calls. Attorneys general also partnered with the effort the FTC calls, “Operation Call It Quits.” 

“At best, these calls represent a nuisance for families just wanting to enjoy peace and privacy without needless disturbances interrupting their routines. At worst, they represent scams that successfully steal people’s identities or hard-earned money,” said Indiana Attorney General, Curtis Hill, in the June announcement. 

Robocallers aim to obtain personal information by calling you, offering a wide range of scams. They can claim to be able to lower your credit card interest rate, offer you money-making opportunities, or provide medical alert systems. There were an estimated 4.7 billion scam phone calls made in July alone — more than 150 million per day. 

Digital Trends reached out to AT&T, Spring, T-Mobile, and Verizon for more details on the pledge, but we have not yet received a response.

T-Mobile’s 5G network just beat Verizon and AT&T (again)
T-Mobile smartphone.

T-Mobile, Verizon, and AT&T always claim to be America's best 5G network in their commercials. T-Mobile boasts this even more so, and as it turns out, it's true. During PCMag's annual Best Mobile Network test (previously known as the Fastest Mobile Network test), T-Mobile won over Verizon and AT&T as the Best Mobile Network for the second year in a row.

PCMag gave T-Mobile the title after testers drove 10,000 miles across the country to measure its performance against Verizon and AT&T. The test involved driving to 30 cities and six rural regions to test each mobile carrier's reliability using Samsung Galaxy S22+ smartphones. As expected, T-Mobile won that contest in 18 cities out of 30, followed by Verizon with eight and AT&T with four.

What is low-band 5G? Sub-6 explained
5G radio tower.

There’s little doubt that 5G promises to change how we communicate, live, and work in a pretty big way. Unlike the cellular technologies of yesteryear, 5G offers capabilities and performance that were once the exclusive domain of wired networks. So, it’s no surprise that deploying these advanced networks has become more involved than anything that’s come before.

To deliver what 5G is truly capable of, wireless carriers have had to work across a much broader range of radio frequency spectrum, from the lower frequencies where the original GSM cellular networks lived, up to those used by radar systems and satellites.

Qualcomm 5G at CES 2019

Gone are the days when 5G was just a buzzword and deployment was experimental. Today, 5G is an established worldwide networking protocol built into most high-quality and flagship mobile devices. 5G stands for fifth-generation mobile technology, and it's destined to replace 4G (and older protocols) worldwide with speeds up to 100 times faster.  Not only is it faster, but it is also more responsive for overall coverage and reception. That means faster uploading and downloading of documents, images, and videos. For home use, it means replacing fiber-optic cable with fast wireless connections.

There are two forms of 5G technology currently in use: Sub-6 relies on lower frequencies to deliver a much larger network, but the trade-off is that you'll receive only marginally faster speeds than you would with 4G. While mmWave connections rely on much higher frequencies that deliver dramatically faster download speeds, those radio waves can't physically travel long distances or make their way through obstacles like walls or even windows, which reduce signal strength.
