No. kimsim plans are data only: no phone number, no normal calls or texts.
But you probably won't miss it:
- WhatsApp, iMessage, FaceTime, Telegram, Signal and the rest keep working on your usual number, over kimsim data.
- Your home SIM can stay on for normal calls and texts (like bank codes). Those are charged at your home carrier's roaming rates, so check them before you go.
- More on calls and texts and WhatsApp and iMessage.
- Keep Data Roaming off on your home line, so it doesn't use data at your carrier's prices. Turn on Data Roaming (and why it matters).
