Pattern-aware, not just keyword-based
Our filter uses message structure, sender reputation and known smishing templates to classify SMS. It catches new variants without waiting for an update.
Junk folder you control
Filtered messages don't disappear — they go to the junk SMS folder where you can review them, restore them or delete them in bulk. Nothing is ever lost.
Trained on real smishing
We sample real smishing campaigns reported by the community to keep the filter aligned with what's actually circulating right now.
- Detects parcel, bank and tax-authority impersonation
- Filters URL-shortener and lookalike-domain links
- Highlights one-time codes from real banks instead of hiding them
- Per-sender override so legitimate alerts always reach your inbox
- Privacy-preserving: messages are scored on-device
FAQ
Will a real package notification end up filtered?
Very rarely. The filter learns from your overrides — once you mark a sender as legitimate, it stays in your main inbox forever.
Does it work on Android?
No. On Android, NoCall does not read your inbox or filter messages: the SMS filter is iPhone-only. If a text looks suspicious, look up the sender's number on NoCall.
Can I disable filtering temporarily?
Yes. Toggle SMS filtering off in settings; nothing is filtered until you turn it back on.
