Send 1000 messages from an android app
An android app that uses your existing phone plan to send 1000 messages at far lower cost than cloud APIs. Includes setup steps, integrations, and a cost table.
TL;DR
FlixySMS runs on an android handset and sends 1000 messages in 10 to 33 minutes using your carrier plan. Per-message cost stays at your normal rate instead of $0.0075-$0.05. Two-way replies and keyword auto-responders work directly on the device. Shopify, WooCommerce, and webhooks trigger sends automatically. Add phones to scale past single-device limits.
What a 1000 message app actually does
An android app for bulk sends runs on your existing handset and uses the SIM card you already pay for. FlixySMS installs directly on the device and queues outgoing texts through the native telephony stack. A single phone handles 30 to 100 messages per minute before carrier throttling kicks in. That speed covers a 1000 message campaign in roughly 10 to 33 minutes.
The app also receives replies so you can run two-way conversations without extra hardware. When an inbound text matches a keyword such as STOP or HELP the system fires an auto-responder you configured earlier. No carrier portal or third-party relay sits between the message and your database.
How the android gateway differs from cloud sms apis
Traditional providers bill between $0.0075 and $0.05 for each segment. FlixySMS removes that line item. You pay only your monthly carrier plan plus one of our flat subscriptions listed on the pricing page. The per-message cost drops to whatever fraction of your plan covers the volume you actually send.
Multi-segment messages longer than 160 characters receive automatic concatenation headers. The receiving handset reassembles them without extra fees. Delivery receipts return through the same android layer so you can log status codes in your own CRM.
Setting up the first campaign
Install the app from the Google Play store and sign in with the same account you use at dashboard. Grant SMS permissions once during onboarding. Next import contacts from a CSV or pull them live from Google Sheets.
Create a group labeled "May 2026 leads" and attach a message template. Schedule the send for 09:00 local time. The queue processes in batches of 200 to respect carrier limits. After launch you can watch real-time delivery percentages inside the same screen.
Required fields for each contact row
- Phone number in E.164 format
- First name for personalization tags
- Source tag for later filtering
- Opt-in date for compliance records
Integrations that trigger sends
Shopify order confirmations fire automatically when a webhook arrives. WooCommerce abandoned-cart reminders use the same hook pattern. Custom webhooks accept JSON payloads from any internal system you already run. Each integration maps to a named template so you avoid hard-coded strings.
Google Sheets serves as a lightweight CRM for one-off lists. Paste numbers into column A, labels into column B, then hit the import button. The sheet stays linked so future updates sync without re-uploading.
Tracking and compliance
Every outbound record stores timestamp, segment count, and final delivery state. Failed deliveries surface with carrier error codes such as 300 or 500. You can retry only the failed subset instead of the entire list.
Keyword handlers cover the most common compliance needs. A STOP reply adds the number to a suppression list stored on the device. HELP replies return a short text with your support number. Both actions complete inside the android app before any network call.
Cost comparison table
| Method | Cost per 1000 messages | Notes |
|---|---|---|
| Twilio / Plivo | $7.50 – $50 | Per-segment billing |
| Carrier plan + FlixySMS | $0.00 – $2 | Depends on your monthly allowance |
| Multi-device cluster | Same flat fee | Parallel sends across 3 handsets |
Scaling beyond one phone
When 100 messages per minute is not enough, add a second or third handset. Each device registers under the same account and shares the contact database. The scheduler distributes load so no single SIM exceeds its throttle window. Three devices routinely clear 3000 messages inside an hour.
Battery and heat stay manageable because the app sleeps between batches. You can leave the phones plugged in on a desk without special cooling.
API access for developers
Programmatic sends go through the REST endpoint documented at api-docs. A minimal curl example posts a JSON array of numbers and a template ID. Responses include batch UUIDs you can poll for final status. Rate limits match the same per-device throughput numbers already mentioned.
Limitations worth stating
The platform respects carrier rules. You cannot exceed the SMS quota printed on your SIM plan. Delivery to some international prefixes may require an extra routing step that adds 5 to 15 seconds per message. We document those prefixes on the status page rather than promising universal reach.
Next steps
Review the current plan limits on the pricing page. Then install the app and run a test list of 50 numbers before your first real campaign. Questions about a specific carrier or integration appear in the faq section.
Frequently Asked Questions
How many messages per minute can one android phone send?+
A typical handset processes 30 to 100 messages per minute. Carrier throttling sets the upper bound. Multi-device setups divide the load across phones.
Does FlixySMS charge per message like Twilio?+
No. You pay only the platform subscription and whatever your carrier plan already costs. The per-message expense drops to a fraction of a cent once volume is spread across the flat fee.
Can I connect Shopify order events?+
Yes. Create a webhook in Shopify that posts to the FlixySMS endpoint. Map the payload to a confirmation template and the app sends the text automatically.
What happens when someone replies STOP?+
The app matches the keyword and adds the number to a local suppression list. No further messages go to that contact until you remove the block.
Is there a limit on message length?+
Messages over 160 characters split automatically with concatenation headers. The receiving phone reassembles them. Extra segments still count against your carrier plan quota.
