After your first login, the app walks you through these setup steps so no critical alert is missed. Each step flows into the next automatically.
Enable biometrics — Face ID / Fingerprint for fast, secure re-entry during incidents.
Enable app notifications — required to receive alerts at all.
Save the OnCall contact — the app saves Vibe OnCall's paging numbers under a single contact named Vibe OnCall: +1 855-780-3813 and +1 848-346-2033 for calls and texts, and +82 2-790-3516 for text pages to Korean (+82) phone numbers. Just confirm the system dialog when prompted; you don't need to type anything in.
When Vibe OnCall adds a paging number, the app asks you once on the home screen to add it to your saved contact. Tap Add number; on iPhone, choose Add to Existing Contact and pick Vibe OnCall. Until the number is on the contact, a Paging number not added card stays on the home screen as a reminder. If you already added the number yourself, tap I've already added it.
