Why didn’t I get the SMS or OTP on the virtual phone number?
There are several possible causes:
- The number reached its SMS limit
- The service you’re registering with blocks virtual numbers
- The message got delayed or wasn’t delivered
- The temporary number expired before receiving the message
- The sender failed to dispatch the OTP
- Some services might block you if your actual location doesn’t match the location of the phone number. In such cases, we recommend using a VPN or proxy from the country you’re trying to register in
If this happens, we recommend trying a different number or refreshing the list.
