How to block spam texts on iPhone

To block spam texts on iPhone, use specific sender blocking for repeat numbers, Apple's unknown sender and text filtering settings for broader separation, reporting tools for scam-like messages, and FingerWag rules when the same spam language keeps arriving from new numbers.

Block a specific spam sender

Blocking is the right tool when the same number keeps texting you. Open the conversation, tap the sender information, and choose the option to block the caller or contact. This can stop that number from reaching you again.

Blocking has a clear limit: it only targets the number you blocked. Spam operations, political texting vendors, and scam campaigns may use many numbers, so blocking should not be your only strategy.

Use Messages filtering for unknown senders

Apple's Messages app can separate unknown senders and gives you a Manage Filtering area where you can review filtering options. In newer iOS versions, look for Filters in Messages, then Manage Filtering, Unknown Senders, and Text Message Filter.

If your device uses older labels, check Settings, Messages, and Unknown & Spam. Apple updates the wording over time, so the exact path can vary by iOS version and region.

Use FingerWag for pattern-based blocking

FingerWag helps when messages keep changing numbers but repeat the same wording. That includes fake delivery language, unpaid fee claims, suspicious prize texts, political fundraising, voter surveys, and campaign disclaimers.

• Turn on FingerWag in Text Message Filter settings.
• Start with built-in spam and political rule patterns.
• Add your own phrases from the messages you receive.
• Review filtered messages occasionally for false positives.
