A Panama eSIM can carry mobile data while the home SIM remains installed for its number. The safe setup depends on assigning each line one role and preventing automatic data fallback.
Keeping a home line active does not make its roaming free. Conventional calls and SMS can still trigger the home operator’s charges even when the eSIM carries data.
NoveSIM Panama plans are data-only, so the home line may remain useful for its normal number while internet apps use travel data.
Quick answer: Select the Panama eSIM for mobile data, enable Data Roaming only on that line, keep home-line roaming off and disable automatic data switching. Label both lines clearly before arrival.

Prepare the labels before the flight
Name the lines Panama Data and Home Number. This reduces mistakes in menus that otherwise show only “Primary”, “Secondary” or two similar carrier names.
The phone may store several profiles while allowing fewer lines to remain active. Check the exact model’s simultaneous-line limit in the device list and manufacturer documentation.
Configure mobile data after arrival
- Turn the Panama eSIM on.
- Select it as the cellular or mobile-data line.
- Enable Data Roaming for the Panama line.
- Open the home line and confirm Data Roaming is off.
- Disable Allow Cellular Data Switching or its equivalent.
- Switch Wi-Fi off and test ordinary browsing.
The activation guide covers registration if the travel line has not yet connected.
Understand calls and SMS
Receiving an SMS or answering a conventional call uses the home operator’s service, not NoveSIM data. Check the home carrier’s roaming fees. Internet calls through WhatsApp, FaceTime or similar apps use the selected data line.
If the wrong line is using data
Switch Wi-Fi off, reopen Mobile Data and verify the selected line. Disable switching again if an update changed the setting. If support requires a manual NoveSIM APN, use data.esim. Keep the installed eSIM; do not delete it to correct line assignment.
Use the Panama troubleshooting guide when the correct line is selected but data still fails.

FAQ
Can I keep my normal number with a Panama eSIM?
Yes, on a compatible Dual-SIM phone. Use the Panama line for data and the home line for its number.
Should roaming be on for both lines?
No. Enable it for the travel eSIM and keep it off for the home SIM.
Can incoming calls cost money?
Yes. Conventional calls and SMS remain subject to the home operator’s roaming terms.
Why disable automatic switching?
It prevents the phone from silently moving mobile data to the home line.
Final Recommendation
A Panama eSIM Dual-SIM setup is safest when each line has a single clear role.
Use the travel line for data and protect the home line from roaming and automatic fallback.
Keep both profiles labelled and verify the active data line whenever settings change.
