kimsim plans are data only. There's no kimsim phone number, so no normal calls or SMS on our line.
Your phone can run two lines at once (dual SIM), so you don't lose anything:
- kimsim does the data.
- Your home SIM stays on for normal calls and texts, including bank codes.
Keep your home line for calls and texts
iPhone
- Settings → Mobile Service → Default Voice Line.
- Choose your home line.
- Then Settings → Mobile Service → Mobile Data → choose kimsim. More on that.
Pixel and most Android Settings → Network & internet → SIMs → set Calls preference and SMS preference to your home SIM.
Samsung Settings → Connections → SIM manager → set Calls and Text messages to your home SIM.
Keep data roaming off on your home line
Otherwise your home carrier can charge for data. Why.
Calling over data
WhatsApp, FaceTime and other calling apps work over kimsim data. Messaging apps.
