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.

Bar Withheld Numbers

  • Block all incoming calls without a caller ID, or choose to receive international calls even if the caller ID is hidden^ to ensure that you don't miss any important calls

Exceptional List

  • In the unlikely event that you want to receive certain marketing calls, you may unblock those callers and add their numbers to your "Exceptional List"
