What SMSFlow Customers Are Saying

Over 5,000 US businesses have already cut their SMS costs to zero. Here are three of them.

"I was bleeding $480 a month on Twilio just to send appointment confirmations. Switched to SMSFlow, now I pay $47/mo flat and zero per SMS. The platform paid for itself in the first 10 days."

Featured Review

"Connected SMSFlow to Shopify via Zapier in under 20 minutes. Now every abandoned cart triggers an automatic SMS. Our recovery rate jumped 40% in the first month. The ROI is ridiculous."

CF

"We use it to send class confirmation texts the night before. No-shows dropped 60%. One retained member covers the entire monthly plan cost. It's a no-brainer for any gym owner."

Frequently Asked Questions

Everything you need to know before you start.

How does SMSFlow send SMS without charging per message?+
SMSFlow turns your Android phone into a physical SMS gateway. Messages route through your SIM card — not a third-party cloud API. You pay only for the platform plan (starting at {price}/mo). Per-message fees: none.
Do I need a dedicated SIM card or phone?+
No dedicated SIM required — any Android phone with any active SIM works. For high-volume professional use, a dedicated budget Android with an affordable unlimited-SMS carrier plan is ideal. Still far cheaper than paying Twilio per message.
Does the Android gateway need to stay on 24/7?+
Yes — the app runs continuously in the background and sends SMS even with the screen off. Just keep it connected to power and wifi. Most customers use an inexpensive Android plugged in at their office or server room.
What integrations are available out of the box?+
Native plugins for WordPress/WooCommerce and Shopify. Pre-built connectors for HubSpot, n8n, Make and Zapier. Plus a fully documented REST API that integrates with any platform, CRM or custom application.
What's the actual difference between Starter, Pro and Business?+
All three include the full web dashboard, templates, API and background mode. The difference is volume: Starter handles 3,000 SMS/month, Pro handles 30,000 and Business handles 100,000 with dedicated support. Every plan includes a 7-day free trial.
Can I scale up for high-volume SMS campaigns?+
Absolutely. Connect multiple Android phones on Pro or Business plans to multiply your sending throughput. Add volume packs for extra SMS on top of your base plan. No artificial caps on campaign size.
