SIM Monkey

SIM Monkey is designed for Android phones with multiple active SIMs. It detects the active subscriptions and gives each one its own caller rules.

Set each SIM independently:

• Allow every saved phone contact or create a separate contact list.
• Silence callers who are not on that SIM's allowed list.
• Leave any SIM completely unrestricted.
• Review a local, privacy-conscious activity history.
• Retest a SIM if the phone's subscription configuration changes.

SIM Monkey does not reject calls or remove them from your call history. It asks Android to silence the ringtone and vibration for calls that match your selected rule.

No advertising. No analytics. No account. Contact matching and call decisions happen locally on the phone.

Compatibility varies by phone, carrier, and Android implementation. SIM Monkey depends on the device reporting eligible incoming calls separately for each SIM. Some phones do not provide this information, so per-SIM screening may not work. Guided Setup tests compatibility before each SIM's silencing control can be enabled.
