The iOS Buddy Helper is Apple’s built-in setup wizard that appears when you install a new eSIM.
It helps you quickly decide:
- Which SIM to use for data
- Which phone line (i.e. which SIM or eSIM) should handle calls and texts
- What to name your new eSIM (we suggest “eSIM Copilot”)
It only takes a few taps, and once it’s done, your iPhone knows exactly how to use your new plan — no extra setup needed.
