As answered by people managing https://alanaknows.com/ and flo-voice1.com.
flo-voice1.com's answer:
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 — 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.
flo-voice1.com's answer:
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 — a rare split in this niche.
flo-voice1.com's answer:
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.
flo-voice1.com's answer:
Built solo by a developer with access to spare physical SIM/GSM gateway hardware, who needed a reliable way to receive verification codes — after seeing how often virtual-number competitors get blocked by strict platforms, turned it into a public rental service backed entirely by real hardware.
flo-voice1.com's answer:
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.
