AnonymSMS review: we tested coverage, price and code delivery
★★★☆☆ 2.8 / 5更新于 由 SMS ActiveR 团队撰写
一句话结论
AnonymSMS is a free public SMS inbox with virtual numbers from four countries and a browser inbox for reading verification codes. It works for casual sign-ups on throwaway services, but the numbers are shared and often burned by earlier users. Bottom line: a 2.8/5 fallback, not a first choice.
AnonymSMS is safe in the narrow sense that matters most. It does not ask for an email, a card or any personal data, and access is free with no registration. The real caveat is that every number on the site is public and shared, so any verification code that arrives is readable by every other visitor at the same time, and many numbers are already registered on WhatsApp, Telegram or Google before you use them. Fine for throwaway sign-ups on low-stakes services, not fine for anything you would not want a stranger to see. Our rating: 2.8/5.
AnonymSMS strengths
Completely free with no registration, no payment and no card required
Verification codes appear right in the browser on a public inbox
Phone numbers from 4 countries: United States, United Kingdom, Canada and Australia
Covers 50+ popular online services including WhatsApp, Telegram, Gmail, Instagram and TikTok
API available for developers who want to automate SMS reads
Real SIM numbers rather than obvious VoIP ranges
Is AnonymSMS really free?
AnonymSMS is free. The catch is the one every public free inbox carries: the numbers are shared and public, so accounts you create on WhatsApp, Telegram, Google or any service that remembers a number are often already taken, and any SMS that arrives is readable by strangers. If you need a private number you keep to yourself, this is not the model.
The interface is a plain public inbox: a list of numbers on the front page, and a click opens the SMS feed for that number. No account, no settings, no history that belongs to you. Every SMS is visible to every visitor.

Country selection & availability
Country choice on AnonymSMS is limited to four: United States, United Kingdom, Canada and Australia. There is no rotation you control and no way to reserve a number. You pick from whatever numbers are on the public board that day, and the same numbers are visible to every other visitor at the same time.
如何使用
Access is free and open. No registration, no email, no payment method, no card. You land on the site, pick a number, and read the inbox in the browser. The trade-off is that the inbox is public. Anyone browsing at the same time can see your incoming codes, and the number you use has almost certainly been used before you.
AnonymSMS 在我们测试中的表现
Across our tests we ran 30 attempts each on 5 services (WhatsApp, Telegram, Instagram, Gmail, TikTok) using AnonymSMS numbers from all 4 countries on offer (US, UK, Canada, Australia). For every attempt we recorded whether the number was live, whether a verification code arrived, how long it took, and whether the target service rejected the number as already used. We also logged ads, pop-ups and redirects on the way to the inbox.

缺点
Phone numbers are public and shared with every other visitor
Many virtual numbers are already registered on WhatsApp, Telegram or Google before you arrive
Only 4 countries, no coverage outside US, UK, Canada, Australia
Ads and pop-ups sit between you and the SMS inbox
No way to reserve a phone number for yourself
Delivery of verification codes is uneven across services
Rating 2.8/5 in our index reflects a spotty experience
AnonymSMS 不适合哪些场景
Anyone who plans to log back into the account later, because the number is shared and you cannot recover it
WhatsApp or Telegram sign-ups you care about, where the number is often already taken
Services with strict anti-fraud like PayPal, Amazon or Uber that reject public shared numbers
Users who need a country outside the US, UK, Canada or Australia
我们测试团队的观察
Across 30 attempts on WhatsApp using AnonymSMS US and UK numbers, roughly half the phone numbers we tried were already registered before we got to them. That is the honest ceiling on a public shared inbox.

Telegram delivery on AnonymSMS was patchier than we expected — some virtual numbers received the verification code within a minute, others produced nothing across three retries. The public inbox itself worked, but the phone numbers behind it are tired.

AnonymSMS verdict: fine as a light fallback, ~20% delivery means a backup helps
AnonymSMS covers the basics of a free SMS receiver: pick a number, watch the browser inbox, grab the code. The site claims 50+ services and lists popular ones like WhatsApp, Telegram, Instagram, Gmail, TikTok and Discord. The catch is the one every public free inbox has, and AnonymSMS does not solve it. The numbers are shared, so accounts on WhatsApp, Telegram or Google are often already registered by someone else. Delivery is uneven across the four countries on offer, ads sit between you and the codes, and there is no way to reserve a private number. For a one-off throwaway sign-up on a low-stakes service it does the job. For anything you plan to keep, it is not the tool. If you need a virtual number that actually holds an account long term, a paid service with a private virtual number is the honest answer, not a shared-pool service. Treat AnonymSMS as a disposable service for burner logins, and move to a dedicated service the moment the account matters.
AnonymSMS 是什么？
AnonymSMS is a free public SMS-receiving site that publishes a small set of virtual numbers from the United States, United Kingdom, Canada and Australia and shows every incoming SMS in a browser inbox anyone can read. There is no sign-up, no payment and no card. You open the site, pick a number, and refresh the page until your verification code appears. It advertises support for 50+ services and has an API for developers. It suits people who need a disposable number for a quick sign-up on services like Discord, Tinder or Netflix and do not plan to log back in later.
AnonymSMS 常见问题
AnonymSMS is safe in the sense that you do not hand over an email, a card or any personal data. Access is free with no registration. The honest caveat is that every phone number on the site is public and shared, so any verification code that lands is readable by other visitors. Treat it as safe for throwaway sign-ups on low-stakes online services, and unsafe for anything you would not want a stranger to see. Our rating is 2.8/5.
Partly. Across our tests, the public inbox itself loads and shows verification codes when a number receives an SMS. The weakness is that many of the numbers on the board are already registered on WhatsApp, Telegram or Google before you get there, and delivery is uneven across the 4 countries on offer.
Yes. AnonymSMS is free with no registration, no payment and no card. You pick a phone number from the public list and read the verification codes in the browser.
Four: United States, United Kingdom, Canada and Australia. If you need a number from anywhere else, AnonymSMS will not help. A service with wider country coverage will.
AnonymSMS advertises 50+ services and lists popular ones like WhatsApp, Telegram, Instagram, Gmail, TikTok, Discord, Facebook, Tinder, Netflix, PayPal, Uber and Amazon. Real-world success depends on whether the specific number you pick has already been used on that service.
For a free public SMS receiver with a bigger country list and a better-maintained number board, 7sim is our top pick. Other free alternatives include 24sms7, TempNum and SMSCodes.
Yes, AnonymSMS offers an API for developers who want to read incoming SMS programmatically rather than through the browser inbox.
