In terms of call blocking, RealCall relies on Verification Code Identification which is not supported by T-Mobile Scam Shield app that works based on voice identification. Compared with voice identification, Verification Code Identification makes RealCall safer than T-Mobile Scam Shield.
The Custom Blocking Rules philosophy supporting RealCall allows its users to block real spam calls, letting go of legitimate calls from government, official banks or hospitals, which is not supported by T-Mobile Scam Shield that possibly blocks both legitimate calls and spam calls.
Although RealCall costs the same price as T-Mobile Scam Shield, they work in different ways and users are able to gain more fantastic features from RealCall. Apart from calls and message blocking, RealCall enables users to customize blocking rules so that the real spam or robo calls or texts can be perfectly filtered with legitimate ones passing through.
Compared with T-Mobile Scam Shield, another essential advantage of RealCall lies in its fraud SMS detection feature that is able to detect dangerous text message scams based on machine learning and send alerts to stop users from clicking the link contained in messages or replying to them. Whenever a suspicious text message arrives, it'll be instantly detected by RealCall that will notify you at the first moment.
