About this tool
- Identifies carrier for any 11-digit Chinese mobile number (China Mobile, Unicom, Telecom, Broadnet, MVNO)
- Validates format: must start with 1, second digit 3-9, total 11 digits
- All processing runs locally in browser — no number is uploaded or stored
- City-level lookup needs a 470K-entry national prefix DB; for that, query the carrier's official site
