Call & SMS Filter is a utility that helps you prevent unwanted calls and SMS messages. It allows you to filter communication based on who is trying to contact you.
There is a wide range of different filtering options within Call & SMS Filter, so you can really pinpoint what you want to come through and what you don't. For instance, you can choose to block all calls, block all SMS messages, block all calls/messages from people not in your contacts lists, or block calls from hidden numbers.
Other options in Call & SMS Filter include the ability to set up blacklists and whitelists, defining specific numbers that are permitted to call or message you. You can even schedule your filters in Call & SMS Filter to activate at a particular time. For instance, you may want to allow unknown numbers to get through during office hours, but not in your free time.
Call & SMS Filter allows you to send an automated SMS reply to anyone who is blocked from contacting you. Alternatively, you can choose to forward these filtered out calls to another number.
All of these features are great, but Call & SMS Filter can be confusing to use. Options and settings are strewn across the user interface in a rather haphazard way, and it takes a while to get used to where everything is.
Overall though, Call & SMS Filter provides a comprehensive and highly customizable call and message screening service for your phone.
