## Description

Number Shield blocks caller ID spoofers by letting you block entire groups of numbers with wildcard patterns. Enter a pattern like 714-555-#### to stop similar numbers and even block international calls, while ensuring your contacts can always reach you.

Block management is accessible from your missed calls screen. Note limits: up to 7 wildcards per pattern and up to 50,000,000 numbers blocked. Blocked calls go to voicemail and blocked texts go to Junk; iMessages are not blocked. See FCC resources at https://www.fcc.gov/spoofing for more info.

## Review summary

User reviews show Number Shield is valued for blocking area codes and its affordable price, but reliability is problematic: it often crashes during setup and fails to block numbers consistently, including texts, leaving calls slipping through despite blocking settings. Some praise the app when it works, but frequent instability and hard limits on number blocks dominate sentiment.

### Pros

- Blocks entire area codes or large number ranges (useful for sweeping spam)
- Low, one-time price with no ongoing subscription
- Silences or diverts unwanted calls to voicemail when functioning
- Described by some users as one of the best call-blocking apps they’ve used

### Cons

- Often fails to block calls/texts; numbers still get through or go to voicemail
- Frequent crashes during the blocking setup (e.g., at ~25–30%)
- Cannot reliably block mass numbers; limits on patterned blocks and area codes
- Blocking for texts is inconsistent or unsupported; not reliable for SMS
- Reliability degrades after iOS updates or with long-term use; app can become unstable
