Traveling thousands of miles away from home is an exhilarating experience, despite minor trepidations. It’s all good as long as your loved ones are a phone call/text message away, you have Google Maps to find your way around, and you can pay for stuff with your phone.

What Is Data Roaming

What I’m trying to say is that internet connectivity is the key to survival in a foreign land. Data roaming lets you use your cellular data even while you’re beyond the borders of your country. However, this privilege comes at a cost, which may turn your dream vacation into a nightmare.

Imagine sipping a fancy drink at sunset on a luxurious resort when you receive a bill from your mobile internet provider that exceeds the cost of your two-way plane ticket. Luckily, you can avoid this mini heart attack by understanding how data roaming works and what you can do to make it work in your favor.

What is Data Roaming?

When you’re in your hometown or touring within the country, your mobile service provider keeps you connected through its own network of cellular towers. On the other hand, when you leave the coverage area of your local provider or travel abroad, you are transferred to a different cellular network.

Data Roaming

This switch of networks to maintain your mobile internet connection is called data roaming, and it is made possible through collaboration between your local service provider and international service providers. When you connect to the partner network outside your country, you incur data roaming charges.

When and How to Use Data Roaming?

You can use data roaming to restore cellular services when you’re outside your carrier’s service area or travelling overseas.

To enable data roaming on your iPhone, go to Cellular Data Options from your phone’s settings. Here you’ll find a toggle switch to turn on data roaming.

For Android, navigate to your phone’s network and internet settings, and select mobile networks. Find the data roaming toggle button to activate.

Why Does Data Roaming Cost So Much?

You could say it’s the cost of convenience – you get to make calls, send text messages, and use the internet uninterrupted, regardless of your location. Nonetheless, there’s a valid explanation for the outrageous pricing.

Data roaming is expensive because agreements between cellular service providers from different countries involve several overheads, such as charges for borrowing the foreign network infrastructure, international tariffs, currency conversion rates, etc. Not to mention, your local provider needs to earn a commission out of this arrangement, so there’s that too.

Tips to Manage Data Roaming Costs

Wouldn’t it be a bummer if you had to break the bank or utilize your retirement savings to pay the bill for data roaming? Nobody wants that, which is why being cautious and strategic is necessary if you choose to utilize this service.

Tips to Manage Data Roaming Costs

Here’s how you avoid paying thousands of dollars for roaming data:

  • Turn on data roaming only when you need to use it; no point in keeping it active on the entire trip.
  • Monitor your data usage and set data limits to avoid surprise charges.
  • Turn off auto-updates, so your apps are only allowed to download updates when you’re connected to a Wi-Fi network.
  • Disable push notifications for unnecessary apps.
  • Close or disable background apps.
  • Use your phone’s data saver option to limit apps that can operate on roaming data.
  • Reserve roaming data for essentials only, such as making an emergency call, booking a ride, checking important emails/messages, etc.
  • Avoid activities like music/video streaming, which quickly use up data.
  • Download maps in advance for offline use.
  • Look for a prepaid data roaming plan offered by your carrier.

How to Avoid Data Roaming Charges?

It’s understandable if you want to avoid data roaming altogether, so you don’t go “yikes” in response to a sudden debt situation later on. Fortunately, there are quite a few alternatives to data roaming, which may fit your budget or cost you nothing at all.

Connect with Public Wi-Fi Hotspots

Most hotels offer free Wi-Fi to their guests. You can also connect to Wi-Fi hotspots at cafes, restaurants, shopping malls, and other public places while you’re out and about. Sometimes you need to purchase something from a local business to gain the Wi-Fi password, but it’s still a sweet deal.

Subscribe to an International Roaming Plan

While you’re in the planning stages of your trip, reach out to your local cellular service provider and ask if they have any international roaming plans. Several carriers, including Verizon, T-Mobile, and AT&T, offer affordable packages, which equip you with sufficient cellular network resources for the entire trip at a fixed price.

Get a Local SIM Card or eSIM

People who travel to specific countries frequently should invest in a local SIM or eSIM. Typically, tourists can buy a physical SIM card at the airport, whereas the eSIM can be purchased and activated on your device digitally. This way, you can enjoy standard data rates from your chosen network on every visit.

Download Content in Advance

You may want to keep yourself entertained with your favorite shows, good movies, and the latest music during the trip. Since data roaming is too expensive for streaming purposes, you can download plenty of content in advance (before leaving the country) and view it offline afterwards.
