Eligibility & Limitations
Battle.net Phone Notifications are designed for text-enabled mobile phones:
- Messaging apps like iMessage (iOS) or WhatsApp (iOS, Android) are not supported.
- Mobile phones with prepaid plans may not work with the phone notification service.
- Phone notifications cannot be used with Voice over IP (VoIP), and VoIP numbers that are transferred to a local provider are not eligible for the service.
A phone number can only be attached to one Battle.net Account.
If you lose your phone but plan to replace it and keep the same mobile number, phone notifications will continue to work as it has before, since it's associated with your phone number rather than the device itself.
