No, when you use a travel eSIM for mobile data, you are not using your home carrier’s roaming, so you typically avoid traditional roaming charges.
However, there are important situations where charges can still happen if your settings are not configured correctly.
Quick answer: eSIM itself does not create roaming charges, but your main SIM can still generate costs if it remains active for data.
Important: Charges depend on your device setup, SIM configuration, carrier policies, and our General Conditions.
Why eSIM Does NOT Use Roaming
When you use a travel eSIM:
- You connect through the eSIM provider’s network
- You are not using your home carrier’s data
- You avoid expensive roaming rates
This is one of the main benefits of eSIM for travel.
When You CAN Still Be Charged
This is where most confusion happens.
1. Your Main SIM Is Still Using Data
If your phone is still using your home SIM for data:
- You may trigger roaming charges
- Your carrier may send warning SMS
Stop Primary SIM from Using Data Abroad
2. Mobile Data Switching Is Enabled
Your phone may automatically switch between SIMs.
Turn Off Mobile Data Switching
3. Background Apps Use the Wrong SIM
If your main SIM is active for data, apps may use it in the background.
4. Calls and SMS on Main SIM
Depending on your carrier:
- Incoming calls may be free or charged
- Outgoing calls may trigger roaming
- SMS may have fees
How to Avoid ALL Roaming Charges
- Select your eSIM as mobile data
- Disable data on your main SIM
- Turn off data roaming for your main SIM
- Disable mobile data switching
- Keep your setup consistent
Check Which SIM Is Used for Mobile Data
Best Travel Setup (Recommended)
- Main SIM → calls and SMS only
- eSIM → mobile data
- Main SIM data → OFF
This setup gives you full control and avoids surprises.
What About Roaming SMS Messages?
Many users receive messages like:
- “Welcome abroad”
- “Roaming charges apply”
This does NOT mean you are being charged.
It simply means your main SIM is still connected to a network.
How to Be 100% Sure You Are Safe
- Check active data SIM
- Monitor usage
- Avoid making traditional calls
- Use apps like WhatsApp instead
What If I Still Get Charged?
This may happen if:
- Main SIM data was used accidentally
- Calls or SMS were made via your carrier
- Settings were not configured correctly
In this case, charges come from your carrier, not the eSIM.
