Android call screening

Scam calls from abroad never ring.

Intl Call Blocker uses Android's built-in call screening to drop overseas robocalls and one-ring Wangiri scams before your phone buzzes. Blocking decisions run entirely on your device.

How it works

Decided before the first ring.

Android hands every incoming call to the screening service. We check it against your rules and answer in milliseconds.

Check the number

Country code is compared with your primary SIM's home country, your blocked countries and your custom prefix rules.

Block or allow

Calls from your blocked countries, and hidden callers if you choose, are rejected at the OS layer. Contacts and everyone else ring through.

You stay in control

Free blocks up to 2 countries, Country Pro up to 5, Premium as many as you like.

Features

Quiet by default. Flexible when you need it.

Smart SIM detection

Sets your home country from your primary SIM automatically.

Blocked countries

Choose exactly which countries to block. Everyone else rings normally.

Contact safe-pass

Anyone in your contacts is never blocked. The lookup happens on-device and nothing is uploaded.

Wildcard rules

Block exact numbers or prefixes such as +1202* or +44*.

Scheduled hours

Only block overnight or on weekends, whichever suits your day.

Cloud sync

Country Pro and Premium sync your settings across devices with a free account.

Pricing
