AT&T and T-Mobile form Partnership to Verify Phone Calls between Networks

Telecommunications companies AT&T and T-Mobile have joined forces to verify phone calls made between their networks in the fight against robocalls…

Last year, Americans received approximately 48 billion robocalls. This represented an increase of 57 percent over the previous year, in 2017. Right now, the average American receives 150 robocalls per year, with some getting as many as 16 to 20 per day.

With the nuisance only worsening, the House of Representatives recently passed legislation to block robocalls. Also, the US Federal Communications Commission voted to allow phone companies to block spam calls.

Now, the telecoms are likewise taking real action to battle the scourge of robocalls. AT&T and T-Mobile have teamed up to verify calls between their respective networks.
