OnlineSMS, a free service available at onlinesms.net, now offers individuals a temporary phone number for situations when a website or app requests a phone number and they prefer not to disclose their own. The visitor selects a number, enters it in the sign-up form, and reads the incoming SMS verification code—the one-time password (OTP)—directly in a browser. No account, top-up, or app installation is required.
The announcement matters because many sign-up forms now demand a mobile number before allowing a person to try a service once, download a file, or leave a review. For a single code, giving out a personal number can result in marketing texts and a phone number stored in another database. OnlineSMS offers a separate, disposable number for that one step, effectively shielding the user's primary SIM card from unwanted exposure.
Using the service involves a simple five-step process: open the list of countries on onlinesms.net and choose one; pick an active number from that country and copy it; enter the number in the sign-up or verification form of the site that asks for it; return to the number's page on OnlineSMS and refresh it until the SMS arrives; then 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.
The core privacy benefit is straightforward: 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 afterward. 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.
However, OnlineSMS explicitly states that its 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, the service says 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. The announcement thus highlights both the convenience and the clear boundaries of free disposable numbers in an era of pervasive sign-up requirements.
