Traveling with your iPhone can make staying connected easy, but international roaming charges can add up quickly if you’re not careful. Fortunately, you can avoid costly fees by using Wi-Fi, local SIM cards, or eSIMs, and adjusting your iPhone’s settings.
In this complete guide, you’ll learn how to prevent roaming charges, use Wi-Fi safely, insert or activate a local SIM/eSIM, and optimize your settings for smooth international travel without surprise costs.
📵 What Are Roaming Charges?
Roaming charges occur when your iPhone connects to a mobile network outside your home country, using a foreign carrier’s service. These charges can apply to:
- Mobile data
- Voice calls
- Text messages
- MMS (photo messages)
Without proper planning, even small amounts of usage can lead to high fees.
✅ Step 1: Turn Off Data Roaming Before You Travel
Before you board your flight, disable roaming to prevent your iPhone from using mobile data abroad.
✅ How to Turn Off Data Roaming:
- Open the Settings app.
- Tap Cellular or Mobile Data.
- Tap Cellular Data Options.
- Toggle Data Roaming to OFF.
💡 You can also toggle Cellular Data OFF completely to prevent any mobile usage.
📶 Step 2: Use Wi-Fi Whenever Possible
Using Wi-Fi is the easiest way to stay connected abroad without incurring any mobile charges.
Tips for Safe and Efficient Wi-Fi Use:
- Use Wi-Fi at hotels, cafes, airports, and public places.
- Enable Ask to Join Networks (Settings > Wi-Fi).
- Use a VPN to protect your data on public Wi-Fi.
- Disable Wi-Fi Assist to prevent automatic cellular usage (Settings > Cellular > Scroll to Wi-Fi Assist > Toggle OFF).
📱 Most communication apps like WhatsApp, FaceTime, iMessage, and email work over Wi-Fi without any mobile data.
💳 Step 3: Use a Local SIM Card or eSIM
Buying a local SIM card or activating an eSIM is a smart way to get affordable data, calls, and texts in the country you’re visiting.
Option A: Physical SIM Card
- Visit a local carrier shop or airport kiosk.
- Purchase a prepaid SIM with a data/call plan.
- Remove your current SIM and insert the local SIM.
- Set up APN settings if prompted (usually automatic).
Option B: eSIM (If Supported)
- Buy an international eSIM from:
- Local carriers
- Global eSIM providers (like Airalo, Holafly, Nomad)
- Open Settings > Cellular > Add eSIM.
- Scan the QR code or enter details provided by the eSIM provider.
- Set the eSIM as your default line or data-only line.
🔁 Dual SIM iPhones let you use both your home SIM and travel SIM together—ideal for keeping your number active while using local data.
📲 Step 4: Manage Your SIM and Data Settings
Once you install a local SIM or eSIM, configure your settings to prevent the phone from using your home plan accidentally.
Steps:
- Go to Settings > Cellular.
- Choose the local SIM/eSIM under Cellular Plans.
- Set as:
- Default Voice Line: For calls and SMS
- Cellular Data: Use the local plan for internet
- Turn off Data Roaming for your home SIM if both are active.
🧠 Additional Tips to Save Money While Abroad
Use Offline Maps:
- Download maps in Google Maps or Apple Maps before your trip.
- You can use navigation without an internet connection.
Disable Automatic Updates:
- Go to Settings > App Store.
- Turn off App Updates and Automatic Downloads over cellular.
Avoid MMS and International SMS:
- Use messaging apps like WhatsApp, Telegram, or iMessage (over Wi-Fi or local data).
Use Airplane Mode + Wi-Fi:
- Turn on Airplane Mode to block all cellular signals.
- Then enable Wi-Fi manually to stay connected without risk of roaming.
🔄 Using iMessage and FaceTime Abroad
Both iMessage and FaceTime work over Wi-Fi or data—but if you’re using a new SIM, your number may change.
To avoid issues:
- Go to Settings > Messages > Send & Receive.
- Add your Apple ID email to continue using iMessage without relying on your SIM number.
- Do the same in Settings > FaceTime.
🔐 Use a VPN for Security Abroad
When connecting to public Wi-Fi abroad, it’s a good idea to use a VPN (Virtual Private Network) to:
- Encrypt your data
- Protect personal info
- Access websites restricted by region
Popular iOS-compatible VPN apps:
- NordVPN
- ExpressVPN

- Surfshark
