Spytm is a free public SMS receiver listing virtual/VoIP phone numbers from India, the USA, the UK, Canada, and Sweden. You don't sign up or hand over your real number. You pick a listed number and watch its public inbox for codes. This review looks at how Spytm holds up across WhatsApp, Facebook, Instagram, Hotstar, Swiggy, Uber, and IRCTC, and where it loses to paid options.
Spytm is fully free. No plan, no top-up, no paid tier. The real cost is reliability. A public number on the board is often already burned, often picks up duplicate SMS noise, and often fails on services that block VoIP.
免费公共号码人人共享：验证码可能被他人读取，同一号码常常已在热门应用注册过。如果账号要长期使用，独享号码更安全。
Spytm uses a plain list dashboard. The home page shows a grid of countries and a stack of recently active virtual numbers. Click a number and you get its public inbox: messages from every service that has used that number, newest first.
Country choice is limited to India, USA, UK, Canada, and Sweden. The skew is clearly Indian. Hotstar, Swiggy, Uber, and IRCTC traffic shows up most consistently. For other regions, the board has little to offer, and fresh numbers thin out fast on the non-Indian lists.
Access is free and needs no registration. You don't connect a wallet, you don't pay per code, and you don't link a real number to the service. The catch is the same one: every listed number is public, so strangers can read the same codes you do.
We ran Spytm through our standard test: 5 countries x 5 services x 30 attempts per service. We checked the public board for fresh numbers, then used each candidate to request codes from popular services. We logged delivery time, the share of numbers that actually receive SMS, duplicate SMS noise in the feed, and how often a number was already burned by someone else. We also tracked ads and pop-ups during the wait.
| 指标 | 7sim | Spytm |
|---|---|---|
| Share of numbers that actually receive SMS | high — carrier-grade SIM numbers, codes arrive in seconds | low — virtual/VoIP numbers are frequently filtered by anti-fraud |
| Delivery time | usually under 30 seconds | variable — depends on public traffic, often minutes or never |
| Chance the number is already used | near zero — single-tenant rental | high — every listed number is public and reused for the same service |
| Ads / pop-ups / redirects | clean dashboard, no ads | ads and pop-ups present during the wait |
| No registration required | fast signup, your personal phone number stays private | no signup at all, but inbox is public |
| Duplicate / garbage SMS in the feed | only your codes in your private inbox | duplicates and unrelated SMS show up in the public feed |

Across 30 WhatsApp attempts on Spytm we saw only a handful of OTPs actually land, and at least one number had clearly already been used to register WhatsApp by an earlier visitor.

— SMS ActiveR test team · Hotstar / Swiggy / IRCTC · 30 attemptsSpytm gets a 2.8 from our test team. The inbox is free and open, but the numbers are public VoIP, shared with anyone who opens the page. For serious accounts, the odds that a code arrives and only you see it are low. Spytm is fine for light throwaway sign-ups on smaller services. For WhatsApp, Facebook, and Instagram, it did not hit verification often enough in our tests to recommend as a primary tool. As a free service, it works best when the target service does not flag shared VoIP ranges, which rules out most major platforms. If your goal is reliable delivery on a real account, pair it with a paid private-number service or skip this service entirely.
Spytm is a free public SMS receiver. You open the site, pick a country (India, USA, UK, Canada, or Sweden), pick a listed VoIP number, and read the inbox in your browser. No account, no payment, no link to your personal number. The catch: every number on the board is shared, so anyone on the internet can read the same incoming messages.
Spytm itself does not ask for personal data, but any verification code sent to a listed phone number is public — anyone watching the same inbox sees your SMS, including codes that could let them hijack the account. Treat it as throwaway only.
Rarely. WhatsApp blocks most virtual/VoIP numbers, and the same Spytm number is reused by many people for the same service, so WhatsApp usually refuses to send the SMS or flags the account. In our 30 attempts very few WhatsApp codes actually landed.
No. The site does not let you reserve a phone number. The number is shared with every other visitor and may disappear from the board at any time.
Smaller Indian online services — Hotstar, Swiggy, Uber, IRCTC — work better than global anti-fraud platforms like WhatsApp, Facebook, or Instagram.
A paid SMS provider gives you a private, single-tenant phone number that you only pay for when the verification code actually arrives. SMS Verification Number is our top pick because it uses real SIM-based numbers that pass verification where free VoIP fails.
