OnlineSMS gives a free temporary number for one SMS code when a site asks for your phone

SPOKANE, WA, October 28, 2026 /24-7PressRelease/ — OnlineSMS, a free service at onlinesms.net, gives people a temporary phone number for the moments when a website or app asks for a phone number and they would rather not hand over their own. The visitor picks a number, uses it in the sign-up form and reads the incoming SMS verification code, the one-time password (OTP), in a browser. No account, top-up or app installation is required.

Many sign-up forms now ask for a mobile number before they let a person try a service once, download a file or leave a review. For a single code, giving out a personal number can mean marketing texts and a phone number stored in another database. OnlineSMS offers a separate, disposable number for that one step.

How to get a one-time SMS code with an OnlineSMS number

1. Open the list of countries on onlinesms.net and choose one.
2. Pick an active number from that country and copy it.
3. Enter the number in the sign-up or verification form of the site that asks for it.
4. Return to the number’s page on OnlineSMS and refresh it until the SMS arrives.
5. Copy the code from the message and finish the verification.

If a code does not arrive, OnlineSMS suggests trying another number from the temporary numbers list. Delivery depends on the sending service, the country and the selected number.

Why OnlineSMS keeps your personal phone number out of the sign-up form

The number on the form belongs to OnlineSMS, not to the visitor. Marketing messages and later texts from that service go to the temporary number, and the visitor’s own SIM card stays out of the process. Reading messages is free and works in any browser, so there is no subscription to cancel afterwards.

The service is also used for testing. A developer checking an SMS sign-up flow can send a message to an OnlineSMS number and see in the browser whether it arrived.

When a shared OnlineSMS number is the wrong choice

OnlineSMS numbers are shared. Anyone who opens the same number can read the messages it receives, and messages are deleted automatically after 24 hours. Because of this, OnlineSMS states that its numbers suit one-time verification and testing, and should not be used for banking, email recovery or any account a person needs to keep. Some services also reject temporary numbers. People who need a number that nobody else can read should use a private rental number instead.

OnlineSMS (onlinesms.net) provides free shared temporary phone numbers from several countries for receiving SMS online. Visitors choose a number, use it for a one-time verification or a test, and read incoming messages in a browser without registering.
