TL;DR
- Calls/SMS: Use home USIM (default voice line). Use data only on eSIM.
- To receive on your home number: enable voice roaming (receive only) or use Wi‑Fi/data services (Wi‑Fi calling, messaging apps).
- Data roaming OFF on home USIM, data only on eSIM → avoid high roaming charges.
Keep default voice = home USIM, cellular data = eSIM. See Dual SIM settings and Domestic SIM roaming off.
