This ensures that the process goes smoothly and that access to your account is not lost at the most inopportune moment. Make sure that your device is connected to a stable network Wi-Fi or mobile data with a good signal.

A critical step is to check access to the new SIM card. Insert it into your smartphone and make sure that you can make outgoing calls and receive incoming calls. Without the ability to receive SMS code or pass voice verification, changing your number is impossible. If the new card has not yet been activated by the operator, complete this procedure first.

Go to Google Play Market and update Viber to the latest available version. This minimizes the risk of technical failures during data migration.

Working with two-factor authentication

Two-factor authentication (2FA) is an additional level of protection for your account. When you change your number, the security system Viber will definitely ask for your PIN code that was set earlier. This is done so that attackers cannot hijack your profile by simply gaining access to your SIM card.

If you have forgotten the set PIN code, the procedure becomes more complicated. You will need the email address you provided when setting up protection. The system will send password reset instructions to this email. However, if mail is also unavailable, you risk losing access to your correspondence history, although your contacts will remain.

In some cases, especially when changing the region, the system may require you to re-configure two-factor protection. This is normal security practice. You will be asked to come up with a new 4-digit code and link it to the new phone number. Do not use simple combinations like 1111 or 1234.
