What is SMS Mobile App?

SMS Mobile App is a free Android application that automates SMS sending using your phone SIM card. It acts as an intelligent SMS agent that receives job instructions from Firebase Firestore and sends messages on your behalf — scheduled, recurring, or in batches.

How do I schedule SMS messages with SMS Mobile App?

Sign in to the app, go to the Jobs page, and create a new SMS job. You can set a specific send time, make it recurring (daily, weekly), or send immediately. The app runs a background scheduler that processes pending jobs and sends them via your device SIM card.

Is SMS Mobile App free to use?

Yes, SMS Mobile App is completely free with no subscription fees, hidden charges, or in-app purchases. Standard carrier SMS rates from your mobile plan apply when messages are sent via your SIM card.

Is my data secure with SMS Mobile App?

Yes. All data is stored in Firebase Firestore with security rules ensuring you can only access your own jobs. Authentication is required for all operations. SMS content is never stored on third-party servers — messages are sent directly from your device SIM card.

Does SMS Mobile App work offline?

Yes, the app is offline-tolerant. You can create SMS jobs even when offline — they are queued locally and synced to Firebase when connectivity returns. SMS sending itself requires cellular signal but not internet.

What permissions does SMS Mobile App need?

SMS Mobile App only requires the SEND_SMS permission to send messages via your SIM card. Optionally, READ_CONTACTS permission lets you pick recipients from your contact list. The app never reads or accesses your existing SMS inbox.

Can I send batch SMS to multiple recipients?

Yes. You can create batch SMS jobs that send the same message to multiple phone numbers. Each message is sent individually from your SIM card, and the app tracks delivery status for every recipient in the job.

Which devices are compatible with SMS Mobile App?

SMS Mobile App runs on Android devices with a SIM card capable of sending SMS. The web interface at smsapp.aoneahsan.com works on any modern browser for job management. Native SMS sending requires the Android app installed on your device.

How is SMS Mobile App different from cloud SMS services?

Unlike cloud SMS services (Twilio, Vonage), SMS Mobile App sends messages directly from your phone SIM card — no API keys, no per-message fees, no third-party routing. Your messages appear in the recipient phone as coming from your real phone number.

Can I set up recurring SMS reminders?

Yes. SMS jobs can be configured as recurring — daily, weekly, or custom intervals. This is useful for appointment reminders, payment due date notifications, birthday wishes, and any other message you want to send on a regular schedule.
