Call Guard
Take control of incoming calls

It was recently reported that some call-blocking apps compile users’ contact lists into a public database. 3 billions of phone numbers and personal information have been disclosed.

SmarTone is committed to protecting your privacy, and our Call Guard service never saves your contact lists. Call Guard has blocked over 100 million junk calls since its launch#, and will continue to provide a hassle-free service to protect you from unwanted calls.
