Spam Message Filter vs SpamGuard

Spam Message Filter 2.0 helps sort unwanted Korean spam and phishing texts from unknown senders into the Messages Junk folder. Protection packs • One-tap packs for Korean spam: ads with (광고) or 080 opt-out numbers, phishing links (parcel, obituary, wedding, or traffic fine stories with a link), loan offers, illegal promotions, stock and crypto leading-room scams, texts from abroad, and election or poll texts (off by default). • Verification-code protection delivers texts that have a 4–8 digit code and no link. Message checker and My rules • Paste a text in the app to see where it would go and why, with matched words highlighted. • Fix a match in one tap (allow the number, allow a word, or turn off a rule) or block a text that slipped through by picking its link, number, or words. • Block or allow by word, number (exact or starts with, e.g. 070), or link domain, and export or import rules as a file to share with family. Privacy and setup • iOS only filters texts from unknown senders, never saved contacts or iMessage. • Judging happens on your device only. The filter extension makes no network requests, never stores or sends texts, and cannot see or count filtered texts or detect whether the filter is on. • No account or login needed. Step-by-step setup instructions are shown for iOS 26+ (in Messages) and iOS 17–18 (in Settings).

SpamGuard filters SMS spam entirely on your device — no server, zero network requests, and your message content never leaves the phone. • Keyword and sender rules with normalization that catches obfuscated spellings • Smishing link detection: blocks shady links (URL shorteners, suspicious domains) combined with lure phrases — delivery, government, embassy impersonation and more, across 15 languages • On-device AI: a built-in Bayesian model gives a second-pass verdict on messages the rules can't decide, and personal training adapts to you • Live test screen: paste a message to see how it gets classified Privacy first: nothing you receive ever leaves your device. Per Apple policy the filter doesn't apply to saved contacts or iMessage. After installing, open Settings > Messages > Unknown & Junk and enable SpamGuard.
