Non-VOIP SMS Verification Service: Receive OTP Codes with Real Phone Numbers
ProSMS is a professional non-VOIP SMS verification service that lets you receive one-time passwords (OTP) and SMS codes online for over 1000 services (Telegram, WhatsApp, Google, Gmail, Facebook, Instagram, TikTok, Discord, Binance and many more) using real phone numbers from 50+ countries — issued by GSM mobile carriers, not Twilio or Google Voice — so they verify reliably even on services that block VOIP numbers.
Non-VOIP vs VOIP SMS — what's the difference?
Most "free SMS" sites you find on Google use VOIP numbers from providers like Twilio, Plivo, Google Voice or TextNow. The problem: Telegram, WhatsApp, Google, Facebook, Tinder, and most banking apps maintain blocklists of VOIP carrier prefixes and reject any verification attempt from those numbers on sight. That's why free sites have a 10–30% success rate.
ProSMS is different. Every number is a real non-VOIP number issued by a GSM mobile carrier — the same kind of number that lives inside a SIM card. It travels over standard SS7/SMPP routes and is indistinguishable from a regular subscriber number to the target service. That's why ProSMS averages 95%+ delivery rates on supported services.
| Property | VOIP number | ProSMS non-VOIP |

| Telegram verify success | ~30% | ~98% |
| WhatsApp verify success | ~10% | ~85% |
| Google verify success | ~25% | ~95% |
| Banking / fintech | Blocked | Works |
| Cost | Free / $1+/mo | From $0.05 / SMS pay-as-you-go |
What is an SMS verification service?
An SMS verification service (also called online SMS receiver or OTP service) is a platform that rents short-term virtual phone numbers used solely to receive SMS messages over the internet. When a website asks you to confirm your phone number with a 6-digit code, you can use a virtual number from ProSMS instead of your real SIM. The code is delivered through the carrier network just like a normal SMS, then surfaces in your ProSMS dashboard within seconds.

SMS verification API for developers
ProSMS exposes a JSON-based REST API (compatible with the popular sms-activate convention) so developers can automate SMS verification in CI/CD pipelines, QA test suites, mobile emulators, and bots. The API supports renting numbers, polling for SMS, cancelling rentals, and querying balance — all in real time.
Pricing & refunds
ProSMS uses a simple pay-as-you-go credit system. Each service and country combination has a transparent credit price shown before you commit. If no SMS arrives within the rental window, your credits are automatically refunded — you only pay for successful deliveries.

Is SMS verification with virtual numbers legal?
Yes. Renting a virtual phone number to receive SMS is legal in most jurisdictions including the US, EU and Vietnam. ProSMS only provides the technical infrastructure — it is your responsibility to comply with the terms of service of the platform you are verifying.
Can I receive a Telegram code on a Vietnamese number?
Yes — VN, US, UK, RU, IN, ID and 45+ other countries are available. Pricing varies by country.
Will my virtual number work with WhatsApp?
Most ProSMS numbers work with WhatsApp on first registration. Note that WhatsApp regularly rotates which carriers it accepts, so success rate varies — auto-refund protects you when it does not work.
