Why does crypto billing make SMSRoute cheaper?
Traditional SMS providers charge via credit card or invoice, adding 2–5% processing fees and often requiring prepayment minimums of $50–$500. The service uses crypto billing (BTC, ETH, USDT TRC-20/ERC-20, XMR, LTC, SOL) — no card fees and no currency conversion; the minimum top-up is $5. Your entire deposit goes to message credits.
Top-ups confirm automatically on the blockchain, and unused balance is refundable to your originating wallet on request. This removes the hidden costs that inflate per-message prices elsewhere. Learn more about funding with USDT on our pay with USDT page.

How does no-KYC make the service cheaper and faster?
Competitors like Twilio, Vonage, and Plivo require identity documents, business registration, and sometimes US 10DLC or India DLT registration — a process that can take days or weeks. The service requires only an email address. You fund your account with crypto, get an API key, and send your first message in minutes.
No KYC means no data retention risk: the service does not store identity documents, so there is nothing to leak. SMS content is not retained after delivery. This privacy-first approach also reduces operational overhead, keeping prices low. For more, see our send SMS without KYC page.
Who should use the cheapest international bulk SMS API?
The service is ideal for developers, startups, crypto projects, privacy-conscious organizations, and any business sending high volumes of international SMS without wanting to pay card fees or wait for KYC approval. It works for OTPs, alerts, marketing, notifications, and two-factor authentication.
If you need custom sender IDs or SMPP, the service supports those on request; inbound numbers are not offered — the service is send-only. For a full comparison with Twilio, read the technical comparison.
