Avoid Samsung Roaming Charges with an eSIM
Quick answer: select the VoyageSIM eSIM for mobile data, turn off data roaming on your primary line and disable automatic data switching if that option appears. Roaming may need to remain enabled on the travel eSIM depending on the plan; always follow its instructions.
Recommended Samsung settings before departure
- Install the eSIM over Wi-Fi.
- In Settings > Connections > SIM manager, clearly identify the primary line and the eSIM.
- At your destination, select the eSIM for mobile data.
- Turn off data roaming and automatic data switching on the primary line.
- Enable roaming on the eSIM only if the plan instructions require it.
Menu names vary by model and One UI version. A line left active for calls or texts can still generate charges under your Canadian carrier’s terms; check those terms before travelling.
If mobile data does not work after arrival
Confirm that the eSIM is enabled, selected for mobile data and that airplane mode is off. Restart the phone, then check the APN and the eSIM roaming setting against the instructions you received.
To add the profile, follow the Samsung setup guide. For compatibility and general use, read the Samsung eSIM guide.
Samsung roaming FAQ
Do I need to turn off my primary SIM completely?
Not necessarily. It can remain active for calls or texts, but charges depend on your carrier. At minimum, turn off data roaming on that line and review its rules.
Why enable roaming on the travel eSIM?
Some plans connect through partner networks and require the setting. This does not mean it should be enabled on the primary line.
Should automatic data switching be enabled?
While travelling, it is generally safer to disable it so the phone does not automatically return to the primary line for data.
