How to change the number in Viber without losing chats, contacts, and access to groups is the question that most often arises when switching to a new SIM card or changing operators. In this article, we will tell you how to change your phone number in Viber so that you can continue to use the application without unnecessary problems. Let's take a look at the preparation, step-by-step steps, possible errors, and settings that are worth checking after updating your number.

Preparing to change the number in Viber

Before changing your Viber number, make sure that the new SIM card is already active and can receive SMS or calls. It is to the new number that Viber sends a confirmation code, without which it will not be possible to complete the change.

  • Make sure you have a new phone number and it works.
  • Save important chats, photos, documents, and contacts if they are valuable to you.
  • Check if you have access to the old number, if you may need it for additional verification or account recovery.

If you only change the number but keep the same phone, the chats are usually saved automatically. If you are switching to a new smartphone at the same time, first make a backup in the Viber settings, and only then perform the transfer.

Steps to change your number in Viber

The procedure for changing the number is performed directly in the application. The names of the menu items may vary slightly depending on the version of Viber, Android or iPhone, but the general logic remains the same.

  • Open the Viber app on your device.
  • Go to the It will or More, then open Settings.
  • Select Account.
  • Press Change phone number or Change Number.
  • Enter the new number in an international format, such as a country code.
  • Confirm the action and enter the code that will be received via SMS or call.

Once verified, Viber will link your account to a new number. Your name, profile picture, most chats and groups should remain available unless you uninstall the app or reset your phone to factory settings.

Problems that may arise when changing the number

Sometimes changing the number in Viber does not work on the first attempt. Most often, the reason is not in the account itself, but in an error when entering the number, SMS delay or lack of backup.

Problem What to check
Incorrect verification code Make sure you enter the last code you received and the number is listed with the correct country code.
Loss of contacts and chats when changing the number Check Viber's access to contacts and the availability of a backup, especially if you have changed your phone.
The need for re-authorization in groups Wait for sync or ask the group admin to re-add you if access hasn't been restored.

If the code does not arrive, do not send requests many times in a row. Wait a few minutes, check your mobile network, turn off the VPN if necessary, and try the call confirmation option.

Entering a new number in Viber

When entering a new number, carefully select the country and check the carrier code. A one-digit error can cause another person to receive a verification code or you may not be able to complete the change at all.

  • Check your privacy settings after changing your number.
  • Give Viber access to your contacts so that the application can correctly synchronize the list of interlocutors.
  • Check the correctness of the new number in your account settings after completing the procedure.

Once you've updated your number, open your profile and make sure your account shows the new phone. It's also worth looking at who can see your photo, online status, information about reading messages and adding to groups.

Notify contacts when a number changes

Viber can automatically notify some of your contacts about the number change. This is convenient if you are actively communicating with colleagues, relatives or customers and do not want to lose contact after switching to a new SIM card.

  • Automatic notification of contacts via Viber helps people understand that the account belongs to you.
  • You can personally write to friends, family or important work contacts about the new number.
  • Warning contacts reduces the risk of misunderstandings, especially if the old number will soon be unavailable.

If you used Viber for work, it is better to separately inform those with whom you conduct important correspondence. Automatic notifications are not always a substitute for a private message, especially in group chats or business communication.

What to do if difficulties arise

If, after changing the number, Viber does not open, the code does not arrive, or chats have disappeared, first check the basic things: Internet stability, correctness of the number, relevance of the application version, and access to SMS.

  • Contact Viber support through the official website or the help form in the application.
  • Check the user forum or the Viber Help Center — there are often solutions for common errors.
  • Try recovering your account through your old number if it's still active and available.

Do not delete Viber immediately after an error if you do not have a backup. Deleting an app can make it difficult to restore your message history, especially if backups have been disabled.

Frequently Asked Questions

Can I change the number without access to the old one?

Yes, but you may need to verify your old number in certain situations, such as when regaining access or doing an additional security check. For the change itself, the main thing is to have access to the new number to get a confirmation code.

Will my chats be saved after changing the number?

Yes, your chats and contacts will be saved if you change the number on the same device and follow the correct steps. If you change your phone at the same time, back up your Viber beforehand.

What other settings do I need to check after changing the number?

You should check your privacy, contact access, backup, and notification settings. Also, make sure that the new number is displayed correctly in the account.

Changing a number in Viber can be a simple process if you follow these instructions: prepare a new number, check the backup, enter the data carefully and confirm the code. If you encounter problems, do not rush to uninstall the application — it is better to check the settings or contact Viber support for help.
