Customers see your number — so they reply.
iSaySo sends your messages through a connected Android phone, straight from your business SIM. The conversation you started comes back to you — with no per-message cost and no unknown number nobody recognises.
Not another SMS gateway. This channel is yours.
Most systems send from a shared number and charge per message. iSaySo turns your business phone into the sending and receiving channel — so the message arrives, gets read, and gets a reply.
Your number, not a service line
Customers recognise the business, so they open, read and reply. A message from an anonymous number is deleted before it's read.
No per-message cost
Your SIM does the sending, and the price is a flat monthly fee. Writing and replying in conversations is never metered; campaigns have a clear daily ceiling. No per-message billing, no surprises.
The phone is half the product
A connected Android phone becomes a full channel: messages out and in, and a real two-way conversation with the customer.
Three steps and you're talking.
No special hardware, no complex install. The phone you already own becomes the sending engine.
Connect a phone
Scan a QR code from the dashboard. The phone pairs in seconds — one device, one pairing — and stays with you.
Send from the dashboard
A single message, a list, a schedule or a full campaign. It all goes out from your number, at a paced human rate.
The conversation returns
Customer replies land in the same screen. "Stop" requests are detected and honoured automatically.
One system for the whole message cycle.
Smart sending
Single, lists, scheduling and recurring schedules, and templates with variables like {name}.
Two-way conversations
Every reply comes back and is linked to the customer and the message it answered.
Contacts and consent
Import from Excel, groups and tags, and consent management per contact.
Devices and health
QR pairing, battery and signal, and daily capacity — the operational facts that matter.
Real analytics
Sent, delivered, replied, clicked. No fake "read" metric — because SMS has no read receipt.
Guardrails and control
Rate throttling, quiet hours and a daily cap that protect your number and your customers.
Numbers you can actually trust.
Every metric here is genuinely measurable. "Read" isn't shown, because it doesn't exist in SMS — instead you get clicks on a dedicated link, a real proxy for interest.
