About Provynx SMS

We built Provynx SMS for private phone verification

Provynx SMS is a virtual SMS platform for receiving one-time passwords on disposable numbers — without tying sign-ups to your personal SIM.

We started with a simple problem: too many services demand a phone number, but none of them should need your real one. Provynx SMS is our answer — live OTP inboxes, US and global routes, wallet billing, and a REST API for teams that need to automate verification.

Verification should be simple, private, and transparent

Whether you are creating a personal account, testing a sign-up flow, or running OTP automation at scale, phone verification should not mean exposing your real number or guessing what you will pay.

We focus exclusively on virtual SMS for OTP — not calling plans, not long-term phone rentals, and not unrelated software services.

Who we serve

Provynx SMS is built for anyone who needs OTP verification without handing over a personal phone number.

Individuals

Keep your personal SIM private when signing up for apps, marketplaces, and messaging platforms that require SMS verification.

Teams & operators

Run repeatable verification workflows with live order tracking, transparent per-route pricing, and a shared wallet for your organization.

Developers

Purchase numbers, poll for codes, and receive webhook events through documented REST endpoints with test keys for safe integration.

What we stand for

Every decision on Provynx SMS is judged against one question: does this make OTP verification simpler, safer, and more transparent for the people using it?

Privacy first

Disposable virtual lines keep your real number out of sign-up flows, testing environments, and one-time verifications.

Transparent pricing

See rates before you order. Top up your wallet, pay only for the routes you use, and skip subscriptions or hidden fees.

Built for speed

Orders, assigned numbers, and incoming codes update automatically so you can copy an OTP the moment it lands.

Developer ready

API keys, webhooks, sandbox mode, and OpenAPI docs for teams automating US and global verification workflows.
