Most online services that send verification SMS (a.k.a. One-Time Passwords or OTP) will not send these verification messages to virtual phone numbers.
We detect verification SMS from major services (WhatsApp, Facebook, Google, Telegram, PayPal, Coinbase and Signal) and show you when we last detected a verification SMS from each service for each number type. Recent detection may indicate a better chance of success, but there is no guarantee.
Using virtual phone numbers for verifying online accounts is at your own risk and we cannot provide support for the online service deciding not to send the verification SMS to your virtual phone number, as we have no control over whether they choose to send the SMS or not.
