10 Proven Tips to Avoid Overpriced Roaming Charges Abroad

You can avoid or substantially reduce international roaming charges by turning off roaming on your home SIM, preparing offline essentials, controlling background use, and choosing a prepaid travel eSIM or a suitable carrier pass.

Roaming lets your phone connect to a mobile network when you travel. Charges can apply to mobile data, calls, SMS, and daily roaming passes. Your phone can also connect to networks near a border, on a ship, in an aircraft, or through satellite service.

A phone may use data without deliberate browsing. App refreshes, cloud backups, navigation, photo syncing, software updates, and Wi-Fi assist features can all use mobile data in the background.

Keep data roaming disabled on your primary home line by default. Turn it on only if you have intentionally chosen your carrier’s international plan. Then select travel data, Wi-Fi, or a carrier pass based on your itinerary and phone needs.

Stay connected as you explore. Choose your travel data before you leave.

1. Choose a travel eSIM before you leave

A travel eSIM for international travel gives you prepaid mobile data abroad without relying on pay-as-you-go roaming from your home carrier.

An eSIM is a digital SIM card built into your device. Many compatible phones can use an eSIM alongside a physical SIM or another eSIM. This dual-SIM setup can let you keep your usual number available while using the travel eSIM for data.

Check these details before you buy:

• Your phone supports eSIM and is carrier-unlocked.
• The plan covers every destination on your itinerary.
• The data allowance and validity period suit your trip.
• The provider lists supported networks for each destination.
• Hotspot or tethering use is available if you need it.
• You can top up if your data runs low.
• The plan includes a phone number if you need traditional calls or SMS.

A checklist for choosing the best eSIM to avoid roaming

There is no single best eSIM to avoid roaming for every traveler. Choose a plan that covers your full route, provides enough data, has clear validity terms, and fits your phone setup.

Orange Travel eSIM is a prepaid option for international connectivity. Orange Travel provides eSIM and SIM options across 200+ destinations. You can purchase, manage, and top up plans online or in the mobile app. Compare Orange Travel world eSIM plans before your trip.

A regional plan can make multi-country travel easier. If, for example, your itinerary includes several European destinations, compare an Orange Travel Europe eSIM plan with separate country plans. To compare providers for international plans, see our guide to the best eSIMs for international travel.

Before you leave

Install your eSIM while connected to dependable Wi-Fi. Save the activation details offline. Activate the travel line according to your provider’s instructions when you arrive.

2. Disable data roaming on your home SIM

Disable data roaming on your home SIM if you do not plan to use your carrier’s roaming package. This is the main protection step against accidental home-line data use abroad.

Turning off data roaming stops your home line from using cellular data on foreign networks. Calls and SMS may still work, and your carrier may charge for them. Check your carrier’s terms if you plan to use your home number.

Settings labels vary by operating system, phone maker, and software version. Search Settings for “data roaming” if your menu uses a different name.

• iPhone: Open Cellular or Mobile Data settings. Select your home line. Turn off Data Roaming.
• Android: Open Network & Internet or Connections. Select your home SIM. Turn off Roaming or Data Roaming.

Dual-SIM setup

• Set the travel eSIM as your cellular-data line.
• Keep data roaming off on your primary or home line.
• Turn off cellular-data switching or “Allow Mobile Data Switching” where available.
• Confirm which SIM handles calls, texts, and data before departure.

Some travel eSIMs need data roaming enabled on the travel eSIM line to connect to a partner network. Keep it off on your home SIM. Orange Travel’s data roaming guide explains the difference.

Activate Airplane Mode

This is the most reliable way to prevent accidental charges. It completely disconnects your device from cellular towers, ensuring your carrier cannot bill you for any background activity.

• The trade-off: Once enabled, you cannot make or receive traditional phone calls or standard SMS (green bubbles/text-only).
• Staying connected: You can manually re-enable Wi-Fi while Airplane Mode is still on. This allows you to use internet-based services like WhatsApp, iMessage, Google Maps (online), and social media without risking roaming fees.

How to Enable Airplane Mode

• On iPhone: Swipe down from the top-right corner—or up from the bottom on older models—and tap the Airplane icon. Then, tap the Wi-Fi icon to reconnect to a local network.
• On Android: Swipe down from the top of the screen to open Quick Settings and tap Airplane Mode. You can then toggle Wi-Fi back on from the same menu.

3. Download maps and travel essentials offline

Offline preparation reduces data use even if you have an eSIM or carrier pass. It also gives you access to key information before your mobile data connects after arrival.

Download these items before your trip:

• Offline maps for the arrival airport, accommodation, major routes, and day trips.
• Translation packs and saved addresses.
• Boarding passes and hotel confirmations.
• Insurance documents and emergency contacts.
• Music, podcasts, e-books, films, and work files.

GPS can usually identify your location without mobile data. Map searches, traffic updates, route recalculations, and place details may need a downloaded map area or an active connection.

Test your offline maps in airplane mode before departure. Download only what you need and carry a charged power bank if you will rely on your phone during the day.

4. Stop background data and automatic updates

Background activity can lead to unexpected international roaming charges. Apps may refresh, photos may upload, email may sync, and your phone may download updates while it is in your pocket.

Set up these controls before you leave:

• Set app-store and system updates to Wi-Fi only.
• Pause photo and file backups until you use trusted Wi-Fi.
• Disable background refresh or background data for nonessential apps.
• Turn off video autoplay.
• Restrict high-quality media uploads on cellular data.
• Review which apps can use cellular data and turn it off for apps you do not need.

Business travelers may need email, work chat, authentication tools, or document apps. Keep those services active only if your travel data allowance supports them.

Restore your usual backup and update settings after you return home. Your files will then back up as normal, and your apps can receive security updates.

5. Use Wi-Fi abroad safely

Hotel, airport, café, and accommodation Wi-Fi can reduce your mobile-data use. Public Wi-Fi needs care because an official-looking network name may not belong to the venue.

Use Wi-Fi abroad safely with these steps:

• Ask staff for the official network name before joining.
• Avoid banking, financial transactions, and sensitive work on unknown networks.
• Avoid entering passwords on networks you do not trust.
• Turn off auto-join for public networks after use.
• Disable file sharing, nearby discovery, and unnecessary device sharing.
• Use HTTPS websites and keep your device software updated.
• Consider a reputable VPN where appropriate.

A VPN can add protection, but it does not remove every risk from an unsafe network. Treat unfamiliar connections carefully.

Check your home carrier’s Wi-Fi calling policy before relying on it abroad. Wi-Fi calling may not remove all charges in every situation. A travel eSIM can also reduce the need to connect repeatedly to unfamiliar public hotspots. Read more about ways to stay connected while traveling.

6. Turn on Low Data Mode or Data Saver

Low-data settings reduce background activity when your phone uses cellular data. They provide a useful second safeguard. They do not replace disabling roaming on your home SIM.

These settings can limit automatic downloads, syncing, image quality, and app refresh.

• iPhone: Enable Low Data Mode for the active travel data line.
• Android: Enable Data Saver. Allow unrestricted data access only for essential apps if needed.

Test important services after changing these settings. Check maps, messaging, ride-hailing, work apps, and two-factor authentication.

Set clear priorities for your travel data:

1. Navigation and maps.
2. Messaging and travel bookings.
3. Payment and security apps.
4. Social feeds, video streaming, and automatic media backups.

This helps your data allowance last for the services you need during the trip. Use the travel data guide to estimate the plan size that fits your travel plans.

7. Use internet-based messaging and calling carefully

WhatsApp, FaceTime, Signal, Teams, and similar services use Wi-Fi or mobile data. They do not use traditional cellular voice roaming in the same way as a standard phone call.

These apps can help you avoid voice roaming fees. They still consume data when you are away from Wi-Fi.

Keep data use lower with a few simple habits:

• Send a text or voice message when a live call is unnecessary.
• Use Wi-Fi for long video calls.
• Use your travel eSIM data for essential calls when Wi-Fi is unavailable.
• Tell friends, family, and colleagues which app to use before you leave.

Receiving or placing a normal call through your home number can still trigger roaming charges, even when mobile data is disabled. If you must stay reachable on your usual number, check whether your carrier has a voice and SMS roaming option that suits your trip.

8. Set data limits and monitor usage

Monitoring helps you notice heavy data use early. It also helps you confirm that your phone uses the correct SIM for mobile data.

Use these checks during your trip:

• Reset cellular-data statistics before departure or at the start of your trip.
• Set a data warning and data limit if your phone supports them.
• Check your eSIM provider app or account for remaining data and expiry dates.
• Review usage after hotspotting, navigation, video calls, or photo uploads.
• Turn off mobile data when you do not need it.

Keep an emergency data buffer for airport transfers, maps, accommodation messages, authentication codes, and travel disruptions.

For full protection from cellular use, turn on airplane mode. You can then manually switch Wi-Fi back on. This prevents your phone from connecting to a mobile network while you use Wi-Fi.

9. Check your carrier’s roaming policy and daily pass

A carrier roaming pass can suit a short trip or a trip where you need your regular number. It is not automatically the lowest-cost choice. Rates vary sharply by home carrier, destination, plan, and type of use.

Check these details before you travel:

• Eligible destinations and excluded territories.
• The daily fee and pass duration.
• Included data and any speed reductions.
• Overage pricing.
• Whether calls, texts, and hotspot use are included.
• Whether the pass starts automatically after first use.
• Data-roaming blocks, spending caps, and usage alerts.

Compare the total expected carrier-pass cost with a travel eSIM that includes the data allowance you need. A low headline price may not show the full cost if a pass activates each day, has limited data, or expires before your trip ends.

Ask your carrier for an account-level data-roaming block if you want calls and texts available but want to prevent all home-line data use. This adds protection beyond your phone settings.

Europe trips need the same preparation. Check your home plan’s fair-use terms, included destinations, non-mainland territories, and coverage rules.

Get a Local SIM Card

Buying a physical SIM card after you arrive is often an affordable choice. Advantages include low upfront costs and the chance to choose from local plans that may offer great value for data and calls. SIM cards are usually available at airports, convenience stores, and mobile shops.

However, there are several drawbacks:

• Finding a store that sells SIM cards can be time-consuming, especially after a long flight or in an unfamiliar place.
• Handling a small plastic SIM can be inconvenient. You’ll need to swap out your original SIM and keep it safe throughout your trip.
• When using a local SIM, you lose access to your regular phone number. This means you might miss calls, WhatsApp messages, or important verification texts, such as those from your bank or workplace.
• Physical SIM cards are easier to lose or damage compared to digital options like eSIMs.
• Some phones are locked to specific carriers and may not accept foreign SIM cards unless unlocked in advance.

If you want a simpler experience, want to avoid these hassles, and prefer to stay connected on your main number, digital solutions like eSIMs offer a more convenient alternative.

Rent a Pocket Wi-Fi

A Pocket Wi-Fi is a small, portable router that connects to a local cellular network and creates a private Wi-Fi hotspot for your devices. You can learn more about the benefits and setup of portable travel routers to see if it fits your trip.

The Pros

• Multi-device connectivity: You can connect multiple devices simultaneously, such as laptops, tablets, and several smartphones, making it ideal for group travel.
• Consistent security: It provides a private, password-protected connection, which is much safer than using unsecured public Wi-Fi in hotels or cafés.

The Cons

• Higher costs: Between the daily rental fee and the data plan, it is often more expensive than buying a local SIM or eSIM.
• Hardware maintenance: It is one more electronic device you have to keep charged throughout the day.
• Portability issues: While small, it is still extra weight to carry in your pocket or bag everywhere you go.

10. Take extra care near borders, on cruises, and in the air

Near a land border, your phone may connect to a neighboring country’s network. That network may fall outside your included roaming zone or eSIM coverage.

Cruise ships, ferries, and aircraft may use maritime, satellite, or onboard networks. These services are often excluded from standard roaming packages and destination eSIM plans.

Cruise/border warning

Do not assume a destination plan covers ships, planes, or every territory nearby.

Protect your connection in these situations:

• Manually select a permitted network where appropriate.
• Keep data roaming off on your home SIM.
• Check the network name before using data near borders or offshore.
• Use airplane mode at sea or in the air unless you have confirmed the network type and cost.
• Review onboard Wi-Fi prices, security, and coverage terms before connecting.
• Confirm travel eSIM coverage before crossing into another country.

Use your travel eSIM only in supported destinations. Check coverage before changing countries or boarding a ship to avoid accidental connections.

Frequently asked questions

How can I avoid roaming charges when traveling internationally?

Disable data roaming on your home SIM. Then use a prepaid travel eSIM, trusted Wi-Fi, or a carrier pass you have checked in advance. Download offline maps and stop automatic updates before leaving.

Should I disable data roaming if I use a travel eSIM?

Disable data roaming on your home SIM. Some travel eSIMs need data roaming enabled on the travel eSIM line to connect to partner networks. Check your provider’s activation instructions carefully.

Can I share travel eSIM data with a hotspot?

A hotspot lets you share your mobile data with another device. Some travel eSIM plans allow hotspot use, while others limit it. Check the plan’s tethering policy before purchase.

Will I Be Charged for Roaming If I Use Wi-Fi?

When you use Wi-Fi for internet-based services, such as messaging apps or browsing, you won’t incur roaming charges because these activities don’t use your mobile carrier’s cellular network. They’re free as long as you’re on Wi-Fi.

However, classic phone calls and SMS (text messages) made through your carrier’s number will still use the mobile network and may result in roaming fees, even if you’re connected to Wi-Fi. To avoid unexpected charges, consider using internet-based calling and messaging apps, and turn off Cellular Data or Data Roaming for extra security. Also, be aware of features like “Wi-Fi Assist,” which might automatically switch to mobile data if your Wi-Fi signal weakens.

Will I Get Charged in Airplane Mode?

No. Airplane Mode disables all wireless transmissions, including cellular signals, Bluetooth, and Wi-Fi. You can manually re-enable Wi-Fi and Bluetooth afterward without any risk of carrier charges.

Will I Get Charged If My Phone Is Turned Off?

If your phone is fully powered off, you won’t be charged for data usage or for receiving calls and texts while it remains off.

However, roaming charges can occur the moment your phone connects to a foreign network. This happens as soon as you turn your phone on and it registers with the local operator, not simply by powering on the device itself.

Regarding voicemail, some mobile carriers may charge for calls that are redirected to your voicemail while you’re abroad, even if your phone is off, because these calls are processed by the network. To avoid unexpected charges, many travelers disable voicemail or use an eSIM plan for all their data needs.

Can I Use WhatsApp on Wi-Fi Abroad?

Yes, absolutely. WhatsApp is an “Over-the-Top” (OTT) app, which means it works as long as you have an internet connection, whether that’s from home Wi-Fi, a public hotspot, or a travel eSIM.

You can send messages, make voice calls, and share videos just like you do at home. The best part? Your WhatsApp account is tied to your phone number, but the app doesn’t require your SIM card to be active for it to work.
