Coral eSIM plans are data-only — no phone number is included, so you can't make carrier calls or send/receive SMS on the eSIM itself.
You can still call and message without any problem:
- App calls: WhatsApp, FaceTime, Messenger, LINE and similar all work over data
- Calls on your home number: keep your home SIM active via dual SIM (setup here)
- SMS verification codes: receive them on your home line (guide)
