How to Avoid Roaming Charges When Using an eSIM Abroad

One of the main reasons travelers switch to eSIMs like AlpineSIM is to avoid expensive roaming charges.
Traditional roaming can cost $5–$15 per day, and streaming a single video abroad could cost more than your flight ticket.
This guide will show you exactly how to avoid roaming fees, use your eSIM correctly, and save money while staying connected worldwide.
1. Understand How Roaming Charges Happen
Roaming charges occur when:
-
Your home SIM card connects to a foreign network for calls, texts, or data
-
Even background apps (like iCloud, WhatsApp, or Gmail) use data without your knowledge
-
Some phones automatically switch to the strongest network if eSIM settings aren’t correct
Key Tip: Simply installing an eSIM isn’t enough—you must set it up correctly to avoid roaming fees.
2. Turn Off Data Roaming on Your Home SIM
The easiest way to prevent roaming charges:
-
iPhone:
-
Settings → Cellular → Select your Home SIM
-
Turn Off Data Roaming
-
-
Android:
-
Settings → Mobile Network → Select your Home SIM
-
Turn Off Data Roaming
-
Optional: You can also disable your home SIM for data entirely to ensure no accidental charges.
3. Use Your AlpineSIM eSIM for Data Only
When abroad, make sure all mobile data traffic uses AlpineSIM:
-
iPhone: Settings → Cellular → Cellular Data → AlpineSIM
-
Android: Settings → SIM Manager → Mobile Data → AlpineSIM
This ensures apps, maps, and background services use your prepaid eSIM plan, not your home carrier.
4. Use Wi-Fi for Calls and Messages
To stay fully connected without roaming:
-
Use Wi-Fi Calling if your carrier supports it
-
Use WhatsApp, FaceTime, or Telegram for free calls and messages
-
Airplane mode + Wi-Fi = zero risk of roaming
5. Pro Tips to Avoid Surprises
-
Enable notifications for data usage on your phone
-
Disable automatic app updates on mobile data
-
Download offline maps and media before trips to save data
-
Check carrier settings: Some carriers allow “roaming blocks” for extra protection
