Each member of your team can add or edit their contact methods anytime through their notifications page. Email address is your default contact method. You can only add two email addresses, two phone numbers for SMS, and two numbers for voice calls at the most. There’s no such limit for the mobile. You can also edit or remove a contact method when necessary.
A rule is automatically created under the “New alert” notification type for every new contact method you add. You can use the rules as they are or modify as necessary.
You can use each mobile device for only one user within the same Jira domain. If another user logs in to Jira with a mobile device that is already being used as a contact method for another user from the same Jira domain, Jira automatically turns off the contact method for the previous user.
