Temporary SMS numbers
Receive SMS verification codes online
HollowSIM gives you a temporary online phone number for receiving verification messages from supported apps. Pick the country and service before you pay, then watch the incoming SMS appear in the same browser tab.
What is a temporary number?
It is a short-term phone number you rent for one SMS activation. Your HollowSIM number remains active for 20 minutes, so you can request and receive the code without adding another SIM card.
How SMS verification works
Choose an available country and app, confirm the displayed price, and rent the number. Request the verification code from the selected app; the received SMS and code appear on your activation page.
Clear rental rules
There is no subscription and the price is shown upfront. If the SMS does not arrive, cancel the activation and the rental cost returns automatically to your HollowSIM balance.
Use temporary phone numbers only for lawful registrations and where the selected service permits them.
The essentialsHave a question?
Have a question?
Here is the answer.
Everything worth knowing before your first number rental.
01How long can I use the number?
The number is available for 20 minutes. That is enough time to request a code and receive the incoming SMS right on the page.
02What if the message does not arrive?
If the SMS does not arrive, you can cancel the activation. The cost is automatically returned to your account balance.
03Can I receive more than one SMS?
Yes. While the rental is active, the page receives every message sent to the issued number by the selected service.
04Which countries and services are available?
Availability depends on the location and app. The current list and price are always shown before payment.
05Do I need to install an app?
No. HollowSIM works directly in the browser on your phone and computer.
