sms-florin (flo-voice1.com) rents real UK phone numbers โ physical SIM cards on EE and Three, not VoIP or virtual numbers โ to receive SMS/OTP verification codes for WhatsApp, Telegram, Google, and 30+ other services. Numbers are available instantly (pay per code, auto-refunded if nothing arrives) or reserved for a full month for repeated verifications. A REST API and npm SDK let developers automate rentals in CI/QA pipelines, and a Telegram bot lets anyone rent a number without visiting the website. Partners who connect their own GSM gateways earn 80% commission on every rental that comes through their hardware.
Real UK SIM numbers
Physical SIM cards on EE and Three carriers โ not VoIP or virtual numbers
Auto-refund
Instant rentals refund automatically to your balance if no SMS arrives within 10 minutes
REST API & npm SDK
Automate number rentals programmatically for CI/QA testing pipelines
Every number is a real physical SIM card in a UK GSM gateway (EE/Three), not a VoIP number or another provider's resold API โ so target platforms see it as a genuine mobile-network number, and the same number can be reused for a full month, not just a single code.
Most cheap SMS-verification services resell VoIP or aggregated virtual numbers, which get flagged or rejected more often by strict platforms. sms-florin uses only real UK carrier SIM cards, auto-refunds instantly if a code never arrives, and gives partners 80% commission for connecting their own hardware โ a rare split in this niche.
Developers and QA teams testing signup/2FA flows that need a real, non-VoIP number, plus individuals who want a UK number for a one-off account verification without exposing their personal number.
Built solo by a developer with access to spare physical SIM/GSM gateway hardware, who needed a reliable way to receive verification codes โ after seeing how often virtual-number competitors get blocked by strict platforms, turned it into a public rental service backed entirely by real hardware.
Next.js (App Router), PostgreSQL with Drizzle ORM, Stripe for payments, a self-hosted GoIP GSM gateway for the physical SIM hardware, plus a Telegram bot and REST API/npm SDK for programmatic access.
