If you received a roaming SMS while using an eSIM, it usually means your main SIM connected to a foreign network—not that you are being charged.
This is a very common situation and often causes confusion for travelers.
Quick answer: Roaming messages are automatically sent by your home carrier when your SIM connects to another network. They do not always mean charges apply.
Important: Charges depend on your SIM usage, device settings, carrier policies, and our General Conditions.
Why You Received a Roaming SMS
1. Your Main SIM Connected to a Foreign Network
Even if you are using an eSIM for data, your primary SIM can still connect for:
- Signal reception
- Calls and SMS
- Network registration
This triggers an automatic welcome or roaming message.
2. Automatic Carrier Notifications
Mobile carriers send messages like:
- “Welcome abroad”
- “Roaming charges may apply”
These are automated and sent regardless of actual usage.
3. Dual SIM Behavior
Your phone can:
- Use eSIM for data
- Keep main SIM connected for calls/SMS
This is normal dual SIM functionality.
Does This Mean I Am Being Charged?
Not necessarily.
You are usually NOT charged if:
- You are not using mobile data on your main SIM
- You are not making calls via your carrier
- You are not sending SMS
You MAY be charged if:
- Your main SIM uses mobile data
- You make or receive certain calls
- You send SMS messages
How to Be 100% Sure You Are Not Charged
- Set your eSIM as mobile data
- Turn OFF data for your main SIM
- Disable mobile data switching
- Avoid making traditional calls
Why This Message Still Appears Even If You Did Everything Right
Because:
- The SIM connects briefly to the network
- The carrier detects international presence
- The SMS is triggered automatically
This happens even if you never use data.
Should I Turn Off My Main SIM?
Optional. Many travelers keep it ON for:
- Receiving SMS codes
- Emergency calls
If you want zero risk, you can disable it temporarily.
