Use a Dominican Republic eSIM as the mobile-data line while keeping the primary SIM available for calls or SMS. The important safeguards are to disable automatic data switching and keep Data Roaming off on the home line.
Dual SIM does not make voice roaming free. Answering a call or sending SMS through the primary number can still be billed by the home operator.
NoveSIM plans are data-only, so ordinary calls and SMS remain assigned to another line.
Quick answer: Label both lines, choose the Dominican eSIM for data, enable roaming only on it and review the home operator’s voice and SMS terms before leaving the primary line active.

Protect the Home Line
- Rename the profiles so the data setting is unambiguous.
- Disable automatic switching before opening travel apps.
- Check which line the phone displays before making an ordinary call.
- Use internet calling over the travel data line when appropriate.
- Ask the home operator how incoming calls, voicemail and SMS are charged abroad.
The guide to keeping a number with a data eSIM explains the general billing distinction.
If the Phone Uses the Wrong Line
Return to the data assignment and switch automatic cellular-data changes off. Confirm with Wi-Fi disabled that the travel line is carrying data. Do not delete either profile while correcting an assignment.
Use the arrival activation checklist if the travel line does not connect after selection.

FAQ
Can both SIM lines stay switched on?
Often yes, if the device supports that combination. Select data deliberately and check home-line voice and SMS charges.
Will incoming SMS use eSIM data?
Ordinary SMS arrives through the line associated with that number, not the data-only NoveSIM profile.
Final Recommendation
Use the Dominican Republic eSIM for data and the primary line only for intentional voice or SMS activity.
Disable automatic switching and home-line roaming before arrival.
Verify the active line whenever the phone’s behaviour or billing matters.
