For those who are unfamiliar, robocalls are phone calls made by robots/machines that dial random numbers in a bid to sell services (fake or legit). It can be very annoying and a waste of time answering these days, which is why organizations such as the FCC have taken steps to fight against it. Now both AT&T and T-Mobile will be working together using the SHAKEN/STIR standards to authenticate calls across their networks.
This means that if you’re an AT&T customer receiving a call from a T-Mobile or MetroPCS number, if it is a legit call it will show as “Caller Verified”, and vice versa. However, we should note that not all phones will support this technology. As it stands, it is supported by a bunch of Samsung and LG devices, but Apple’s iPhones have yet to support it, so that’s something to take into consideration.
As we said, the FCC has taken steps to fight against robocalls where they recently announced that carriers can now block robocalls by default.
