How to change your phone number on Viber and keep your chats

Updated 7 November 2026 · The ReserveSMS team

In short

  • Viber’s Change phone number moves your account to a new number, and your account looks the same as before.
  • People with your current number saved see a banner in your chat and can save the new one. Blocked contacts aren’t told.
  • Back up your chat history first. Chats can’t move between Android and iPhone.

Viber can move your account to a new number, so you don’t start from scratch.

Back up first

Back up your chat history before you change anything. If you’re changing your phone as well, Viber says to back up on the old phone, change your number, then activate Viber on the new phone. Chat history is tied to Android or iOS and can’t move between them.

Change the number

Go to More, then Settings, then Account, then Change phone number, and enter the code sent to the new number.

Who gets told

Anyone with your current number saved gets a banner in your existing chat, with the option to save the new number. Contacts you’ve blocked aren’t told.

Keeping your old number

You can keep using your old number on Viber after a SIM change, but Viber warns that if your account is deactivated or you reinstall, you won’t be able to receive the activation code.

After a one-time number

Viber sends an activation code when you reinstall, and a one-time number from ReserveSMS receives codes for 20 minutes only, so move the account to a number you keep. See Viber activation codes.

Common questions

Do I lose my chats if I change my Viber number?

No. Viber says your account looks the same after the change. Back up your chat history first anyway.

Will my Viber contacts know my new number?

People with your current number saved see a banner in your chat and can save the new number. Blocked contacts aren’t told.

Can I move Viber chats from Android to iPhone?

No. Viber says chat history is tied to Android or iOS and can’t be transferred between them.
