Protecting Personal Phone Privacy
Avoid sharing your personal phone number when opening new email accounts online. A temporary virtual number handles SMS verification without linking your real mobile line to web databases.

Temporary Virtual Phone Numbers for Fastmail Verification
Setting up a new email inbox or updating security settings on Fastmail frequently requires a valid mobile phone number for SMS verification. Handing over your personal phone number to online services increases the risk of unwanted text messages, spam calls, and third-party data tracking. Once your primary mobile number is connected to an email service, your personal identity becomes linked across multiple web accounts and marketing databases.
Using a temporary virtual phone number offers a practical answer to this privacy challenge. It allows you to complete the account verification process quickly while keeping your real SIM card and contact information completely private. OnayApp enables you to receive incoming verification messages instantly without signing up for long contracts or exposing your primary line.
The service operates on iOS and Android using an in-app coin system rather than a recurring subscription. You simply purchase coins and spend them whenever you need a number. Options for Fastmail include regions like England, Ukraine, Vietnam, Indonesia, Georgia, Kyrgyzstan, and Russia, with single-use temporary numbers priced at 1 coin.
When you request a temporary activation, the number stays reserved for approximately ten minutes. SMS verification codes arrive in real time through push notifications in the app. If no message is received during the reservation window, your coins return to your balance automatically. Longer rentals are also available if you require extended access to the same number over time.
