They can also disable SMS for some users and remove them from the campaign. > [!NOTE] > Note > > The automated SMS opt-out opt-in feature applies specifically for UC SMS, and only for numbers using campaigns in North America. ## Requirements and limitations Before assigning users to an SMS campaign: - Your SMS campaign must be approved and verified ([Brand Registration](/documentation/docs/sms-registration-brand-and-campaign-registration#brand-registration) and [Campaign Registration](/documentation/docs/sms-registration-brand-and-campaign-registration#campaign-registration)). - Campaigns are available only in US and Canada. - By default, each SMS campaign allows up to 48 phone numbers. To request more than the default number of allowed phone numbers, you can contact 8x8 support once your campaign has been approved. > [!WARNING] > Important > > - Only one phone number per user can be enabled for SMS. > - Enabling a different number will disable the previously enabled number automatically. > - The Deactivate campaign button permanently disables SMS for all phone numbers in the campaign. This action cannot be reversed. **Enable SMS for a user via User Profile** You can assign users to an SMS campaign only after SMS Campaign Registration is complete and verified.
