- FlixySMS stores received messages so teams can review sender, device, time, and message history.
- Stable numbers are better suited for Shopify alerts, WooCommerce notices, and customer support replies.

Learn what a temp phone number for text messages actually is and how FlixySMS lets you run the same workflow on your own Android device without per-message carrier fees.
TL;DR
A temp phone number receives texts on a secondary line. FlixySMS installs on any Android handset and turns it into a self-hosted gateway that uses your existing carrier plan, removing the per-message fees charged by most virtual-number providers.
A temp phone number for text messages is simply a secondary line you activate only when needed, often for verification codes, two-factor logins, or short-term marketing tests.
Why businesses still reach for temporary numbers
Many teams grab a temp line because carrier plans throttle or cost extra once volume rises. A single Android handset running FlixySMS can send 30 to 100 messages per minute while charging only your existing carrier rate spread across the flat monthly fee.
How FlixySMS replaces paid temp services
Instead of renting a virtual number from a third party, install the app on an old Android device and point it at your existing SIM. The phone becomes the entire gateway. No per-message fees from Twilio-style carriers appear on the bill.
Real hardware limits you should know
- One device: 30-100 SMS/min depending on carrier
- Two devices in parallel: roughly double throughput
- Multi-segment messages over 160 characters split automatically with concatenation headers
Setting up your first gateway in minutes
Connect the phone to Wi-Fi, grant SMS permissions, and scan the QR code shown in the Dashboard. The device appears online within thirty seconds and starts accepting API calls.
Common use cases with concrete examples
- Shopify order confirmations sent the moment a customer checks out
- WooCommerce abandoned-cart reminders triggered two hours after cart abandonment
- Google Sheets bulk import of 500 contacts that fires at 9 a.m. local time

Pricing tiers and quota reality
Check current limits on the Pricing page. The Free tier covers light testing; Business and Enterprise plans raise monthly SMS quotas without changing the per-message cost structure.
Two-way conversations and auto-responders
Inbound messages can trigger keyword replies such as STOP or HELP. This satisfies compliance without extra services. Configure rules once and they run on the device itself.
Comparison table
| Approach | Per-message cost | Setup time | Reliability |
|---|---|---|---|
| Online temp services | $0.0075–$0.05 | 2 minutes | Carrier dependent |
| FlixySMS on Android | Carrier rate / subscription | 5 minutes | Local signal |
When to choose the Android route
If you already pay for an unlimited texting plan on a spare phone, the effective cost drops to pennies per month after the subscription. Traditional gateways add fees on top of that.
Learn more setup details on the How it Works page.
Limitations worth stating
Delivery depends on the carrier signal at the phone's location. Keep the device powered and in range. Quotas reset monthly; monitor usage inside the dashboard.

Frequently Asked Questions

Install FlixySMS on a spare Android device with an active SIM. The app turns the handset into a gateway that receives and sends messages using your current carrier plan.

Messages stop until the next billing cycle or until you upgrade the plan. Current limits are listed on the pricing page.
Does FlixySMS support multi-segment SMS?+
The app automatically splits messages longer than 160 characters and adds the required concatenation headers so the recipient sees one complete text.
