T-Mobile, in an announcement on November 8, claimed that more than 1 billion scam calls has been blocked by it after launch of its Scam ID and Spam Block feature 18 months ago. T-Mobile is also all set to implement FCC SHAKEN/STIR standards let the user to receive verified only calls. SHAKEN (Secure Handling of Asserted information using tokENs) and STIR (Secure Telephony Identity Revisited) standards permit carrier companies to verify genuineness of call being received by the customer.
With a per day estimate of 147 million, Robocalls has been striking the highest ever mark and minimum entry requirement has made it easier for anyone to become a robocaller. This trend also facilitated the scammer towards neighborhood spoofing.
Scam ID and Spam Block feature has been improved by T-Mobile to counter such robocalls. Built in feature of T-Mobile’s Scam ID flags the robocalls as “Scam Likely” and same message will be shown to customer screen allowing him to decide whether to receive the call or not as there is a chance system may mark a legitimate call as scam likely. Whereas its Spam Block entirely blocks the “Scam Likely” tagged robocalls, a features which have to be activated by customer.
Call screening for caller authenticity is the safest way to protect the customers from scammers as last year Americans had received 30 billion spam calls costed a total of $350 million to them. In an analysis by First Orion, a call protection company, it revealed that in 2017 about 3.7 percent of the total calls were spam, which will be increased to 29.2 percent in 2018 and predicted to be 44.6 percent till the end of 2019.
T-Mobile has also showed its consent to adopt FCC frame work namely SHAKEN/STIR, which demands stronger call authentication system to be adopted by the carriers.
