# SMSApp documentation > Public documentation for an owner-operated Android SMS dispatch system with a web administration panel. The Android app `com.aoneahsan.smsapp` version 1.7.0 is live on Google Play as "SMS Mobile App": https://play.google.com/store/apps/details?id=com.aoneahsan.smsapp. The web admin prepares and monitors jobs. ## Product contract - One selected, owner-managed Android phone per job. - Enrollment is explicit and off by default. - The phone sends through one configured default SMS subscription. - Recipient sources are that phone's completed contact sync or a UTF-8 CSV up to 5 MiB. - A job contains at most 5,000 unique eligible recipients. - Only ordinary Pakistani mobile numbers in `030`–`036` are eligible. - Foreign, landline, short, service/premium, malformed, and unrecognized destinations are excluded without override. - Firebase coordinates authenticated state; it is not an SMS gateway. - The app never reads received SMS and is not a default SMS handler. - Android sent callbacks do not guarantee carrier delivery. Uncertain outcomes need owner reconciliation. - Carrier charges, consent obligations, and platform limits still apply. ## Documentation map - Introduction: https://smsapp-docs.aoneahsan.com/ - Tutorials: https://smsapp-docs.aoneahsan.com/tutorials - How-to guides: https://smsapp-docs.aoneahsan.com/how-to - Reference: https://smsapp-docs.aoneahsan.com/reference - Explanation: https://smsapp-docs.aoneahsan.com/explanation - Sitemap: https://smsapp-docs.aoneahsan.com/sitemap - Feed (RSS): https://smsapp-docs.aoneahsan.com/feed.xml - Public repository: https://github.com/aoneahsan/smsapp-docs
