The best call and sms blocker in the Play Store period. Call Master is the only blocker that when you choose to block a number or sms, you won't hear anything. Most call blockers will ring one, then block the call or sms. Loaded with features: block only calls, block only sms, block both, block certain numbers during certain times of the day, automatically respond to a blocked sms with your own customized message, send calls directly to voicemail, make it so the caller just hears rings and it will not hit voicemail, when callers dial your number have them hear nothing at all! Plus more features! The only downside is that it is a little confusing to get it setup, but you get the hang of it pretty quick and it's worth taking the extra time to learn it than to go to an inferior call blocker.
