How to block spamming SMS I am using a MOTO-G6 and it runs on Android-8.0.0. the default SMS app is Google-Messages.

I am getting tons of annoying spam SMS from contacts with no numbers.
It just shows a name for example:

VKHLTCHK
HPFAMDOC
HPYESBNK
...
...


I can block these contacts, But I still do receive sms from these over and over again.

Has anyone have this kind of problem. How do you solve this? I am  willing to buy a paid app if it exists.
Try replacing your stock SMS app with Textra (free). It has a simple &amp; effective blacklist feature. Just long press on the offending text message, tap Blacklist, done.
