How to Avoid Roaming Charges When Traveling: 5 Easy Ways

International roaming can be convenient—but it can also make staying connected abroad much more expensive than expected. Your phone may use mobile data in the background for maps, email, app updates, cloud backups, and social media, even when you are not actively browsing.

The good news is that avoiding roaming charges is simple once you know your options. This guide explains what roaming is, why it costs more, and how to stay online abroad with more control over your travel budget.

What is roaming?

Roaming happens when your phone connects to a mobile network outside your regular provider’s coverage area.

For example, if your home mobile provider is in the United States and you travel to Japan, your regular SIM may connect to a Japanese network through an agreement between the two providers. This allows you to keep using calls, texts, and data—but it may come with additional charges.

Roaming can apply to:

• Mobile data: using maps, websites, apps, email, video, and social media.
• Calls: making or receiving calls through your regular mobile number.
• Text messages: sending or receiving standard SMS messages.

The exact cost depends on your provider, your home plan, and the country you are visiting.

Why are roaming charges expensive?

Your home provider does not own mobile towers and network infrastructure in every country. When you travel, it may pay a local carrier to provide service to your phone, then pass those costs on through its international-roaming rates.

This is why daily roaming passes can feel expensive, especially on longer trips. They may also include data limits, and additional usage can cost more once you exceed the allowance.

Data is usually the biggest concern. A few minutes of video, automatic photo syncing, or downloading files can use far more data than messaging or checking maps.

5 ways to avoid roaming charges while travelling

1. Use Wi-Fi carefully

Hotels, cafés, airports, and public spaces often provide Wi-Fi. Connecting to Wi-Fi can help you avoid using mobile data from your home SIM.

However, Wi-Fi is not always available when you need it. It can also be slow, unreliable, or unsafe on public networks.

Wi-Fi is useful for large downloads, video calls, and backups, but it is not ideal as your only way to stay connected. You may need data while navigating, ordering transport, checking a booking, or finding help outside your hotel.

If you use public Wi-Fi, avoid accessing sensitive information unless necessary and consider using a VPN for extra protection.

2. Check your home provider’s roaming pass

Many mobile providers offer international add-ons or daily roaming passes. These may include a fixed amount of data, calls, and texts for a daily fee.

This can be a suitable option for a very short trip, especially if you need to keep using your normal mobile number for calls.

Before you rely on a roaming pass, check:

• The daily price
• Included data allowance
• What happens when you exceed the limit
• Countries covered by the pass
• Whether the charge applies every day or only on days you use data

For longer trips, a prepaid travel eSIM is often easier to control because you choose the data plan before you travel.

3. Turn off roaming on your primary SIM

Turning off data roaming on your primary SIM prevents it from using expensive international mobile data.

On iPhone:

1. Open Settings.
2. Tap Mobile Data or Cellular.
3. Select your primary SIM.
4. Tap Mobile Data Options.
5. Turn Data Roaming off.

On Android, the exact menus vary by phone, but generally:

1. Open Settings.
2. Go to Connections or Network & Internet.
3. Select Mobile networks.
4. Turn Data Roaming off.

You can also set your primary SIM not to be used for mobile data while abroad.

If you install an egoViet travel eSIM, check its instructions before changing settings. Many travel eSIMs need Data Roaming turned on for the egoViet eSIM line in order to connect to a local network. Keep roaming off on your primary SIM, not necessarily on the travel eSIM.

4. Buy a local physical SIM card

A local SIM card can give you data, calls, and texts at local rates. You can usually find one at airports, convenience stores, or mobile shops after you arrive.

This option can work well, but it has a few drawbacks:

• You need to find a trustworthy seller after arrival.
• You may need to show identification in some countries.
• You must remove your main SIM card.
• You need to keep your original SIM safe throughout the trip.
• You may not be connected immediately after landing.

If you prefer to keep your original SIM in your phone and set up your data before departure, a digital eSIM is a more convenient alternative.

5. Use a prepaid travel eSIM

A travel eSIM lets you buy mobile data online and install it directly on your compatible phone. There is no physical SIM card to swap, and you can prepare your connection before you leave.

With an egoViet eSIM, you can choose a prepaid data plan for your destination, install it digitally, and connect to supported local networks when you arrive.

Benefits of using an eSIM for travel include:

• Buy your plan online before your trip.
• No physical SIM card needed.
• Keep your primary SIM in your phone.
• Use your usual number for calls, texts, or WhatsApp where supported.
• Choose a data allowance that matches your trip.
• Avoid relying on your home carrier’s international roaming data rates.
• Easily add another eSIM for your next destination.

Most modern phones can store multiple eSIM profiles, although the number that can be active at the same time depends on your device.

How to get started with an egoViet eSIM

Getting connected with egoViet is simple:

1. Confirm that your phone is unlocked and eSIM compatible.
2. Visit the egoViet eSIM store.
3. Choose a plan for your destination and travel dates.

You will be ready to use maps, ride-hailing apps, messaging, travel bookings, and more without searching for a SIM-card shop on arrival.

Stay connected without surprise roaming costs

Roaming is not your only option when travelling internationally. You can use Wi-Fi, choose a roaming pass, buy a local SIM, or use a prepaid travel eSIM.

For most travellers, an eSIM offers a simple balance of convenience, flexibility, and cost control. Instead of waiting until you arrive, you can choose your data plan in advance and start your trip ready to connect.
