At a glance

How to set dual SIM so only eSIM is used for data with USIM still in the phone.

TL;DR

  • Dual SIM (USIM + eSIM): Set data to eSIM, default voice/SMS to home USIM. Data roaming OFF on home USIM to avoid high roaming.
  • Same idea as Dual SIM eSIM data and call settings: data = eSIM, voice = home USIM, home data roaming OFF.
  • Check Domestic SIM roaming off for step-by-step. Compare plans.
