Commercial aspects
How do I reactivate an ID?

To reactivate the ID you should send the ID reactivation request. Such a request can be sent any time you need it. Once the ID is activated, you have to pay the MMC for the whole month.


What happens if the brand wants to stop sending out Viber campaigns temporally?

There are 2 options available:

Option 1.

You send GMS the Service ID deactivation request. Such a request should be sent before the billing date. This way, you avoid the MMC payment for the given ID.

Example: You would like to have an ID deactivated starting July. Therefore, the request should be sent no later than June 29. If the request is sent on July 1 or later, the ID will be deactivated only next month – in August. In such a case, the MMC fee for July will be applied.


Option 2.

You leave the ID active and do not send the request at all. In this case, you will pay the MMC for this ID.

Please note: Viber allows for up to 3 ID deactivations per year. After 4th deactivation the ID automatically becomes inactive and can`t be activated till the end of the current year.

How much do I pay for using Viber Business Messages?

The price for the messages sent depends on:

  • destination: the country brand sends messages to
  • traffic type: transactional or promotional
