What is data roaming?

Data roaming is like borrowing a friend’s Wi-Fi when you’re out of range of your own network. When you leave your home country, your mobile provider doesn’t follow you around like a lost puppy. Instead, it borrows another country’s network so you can stay connected. This service is what we call "data roaming."

It means your phone is using a foreign network to access the internet, make calls, or send texts. Roaming is incredibly convenient for staying connected when you’re traveling internationally; whether you're getting directions, messaging your friends, or scrolling Instagram at a cafe in Paris. However, this convenience comes at a price, and understanding how roaming works can help you avoid some of those unexpected charges that can ruin a good trip.

How does data roaming work?

Data roaming works by making your mobile provider partner with another network in a different country. Think of your provider as a special guest at an international event; it gets temporary access to use other mobile networks, allowing you to stay connected while traveling. This lets you make calls, send messages, and use mobile data even when you're nowhere near home.

When you enter a new country, your phone automatically searches for available networks and connects to one that has a roaming agreement with your provider. You might see your signal icon switch to a different network name or logo when you cross a border - that's your phone saying, "Hey, I'm on a different dance floor now!" But just like VIP entry, roaming comes with a cost. Those data transfers don’t come cheap, and the rates can be surprisingly high if you don’t have a suitable international plan.

Roaming charges are calculated based on the amount of data you use, the number of texts you send, or the minutes of calls you make. The exact cost depends on the agreements between your home provider and the network you're using. To avoid bill shock, it's important to be aware of these costs before you start using your phone abroad.

When should you use data roaming?

Data roaming can be a lifesaver, but it’s not always a great idea to keep it on. Here’s when it makes sense:

• You’re in a country without reliable Wi-Fi access.

• You’re waiting for an important email while on the move.

• You need GPS navigation in areas where you can’t connect to a Wi-Fi hotspot.

For casual travellers, roaming might just be an emergency backup. For frequent travellers? It's likely time to consider alternatives. If you know you'll need consistent connectivity, it's better to look into international SIM cards or portable Wi-Fi devices. Roaming is great for short-term needs but can quickly become prohibitively expensive if used as your main source of data abroad.

Pros and cons of data roaming

Pros:

• Convenience: No need to buy a local SIM or hunt down Wi-Fi.

• Constant connectivity: Handy when you're in transit or traveling through rural areas.

• Same number: Your contacts can reach you without a different number.

Cons:

• High cost: Your next phone bill might give you a heart attack. Roaming rates are often much higher than domestic rates, and a few minutes of browsing can end up costing you dearly.

• Unpredictable charges: Roaming fees vary wildly depending on where you are, which can make it hard to predict your expenses. Different countries and different providers have different rates, which means that keeping track of costs can be a nightmare.

• Battery drain: Your phone works overtime looking for foreign networks, which can drain your battery faster. Constantly switching between networks, especially in remote areas, can make your phone’s battery life plummet.

How to avoid excessive data roaming charges

• Turn off data roaming: It sounds obvious but turning it off is the easiest way to dodge crazy charges. Make sure to switch off data roaming in your settings before you even leave your home country.

• Use Wi-Fi hotspots: Find a cafe, hotel, or public space that has Wi-Fi. Many restaurants and hotels offer free Wi-Fi for customers, which can be a great way to stay connected without using mobile data.

• Get an international data plan: These plans can save you from the cost surprises that come with regular roaming fees. Many providers offer international roaming packages that include a set amount of data for a fixed price, which can be far cheaper than paying standard roaming rates.

• Monitor your data usage: Apps like My Data Manager can help you track data usage while you're abroad. Monitoring your usage in real-time can help you stay within limits and avoid unnecessary charges.

• Airplane mode: When you’re not actively using your phone, consider turning on airplane mode. This ensures you won’t accidentally use data in the background.

Tips for managing data usage abroad

• Download maps beforehand: Use offline maps apps, like Google Maps’ "Download for offline use." This way, you can access maps even when you’re not connected to the internet, saving you from using precious mobile data.

• Turn off background data: Disable apps from updating in the background by adjusting your settings. Apps like Facebook, Instagram, and email clients often update automatically, which can use a surprising amount of data.

• Limit streaming: Your favourite show on Netflix might be tempting, but it’ll eat through your data allowance and your budget. Instead, download shows or music before you leave home so you can watch or listen offline.

• Use data compressing apps: Apps like Opera Max can help reduce the amount of data used by compressing images and videos, making your data go further while you’re on the move.

Alternatives to data roaming

• eSIMs: eSIMs are one of the most flexible and convenient options for travellers. They allow you to use local networks at cheaper rates without the need for a physical SIM card. With eSIMs, you can easily switch between different carriers right from your device settings, making it ideal for frequent travellers or those visiting multiple countries. eSIMs also mean you don't have to worry about losing a physical card or swapping SIMs, which can be a hassle during your journey. Providers like Bonjola offer affordable travel eSIMs with global coverage, saving you from the high fees of data roaming.

• International SIM cards: These cards allow you to use local networks at much cheaper rates than roaming. However, unlike eSIMs, they require you to replace your current SIM card, which can be inconvenient and often means getting a new phone number.

• Portable Wi-Fi hotspots: These devices create a personal Wi-Fi network, allowing you to connect multiple devices. They’re great for families or people traveling in groups, but they can be costly upfront and require charging, which might not be ideal for everyone.

• Local SIM cards: Purchasing a local SIM card at your destination can often be the most cost-effective solution, especially for longer stays. However, it means replacing your current SIM, which can be inconvenient, and you’ll have a new phone number.

• Relying on Wi-Fi: Many hotels, cafes, and public places offer free Wi-Fi, which can be used for messaging, making calls via apps, and accessing the internet. However, free Wi-Fi may not always be available or secure.

• International data plans from carriers: Some mobile providers offer international data plans for a fixed cost. These are usually more affordable than using standard roaming rates and can be a good choice for convenience.

How to enable or disable data roaming on your device

• iPhone: Go to Settings → Cellular → Cellular Data Options → Toggle Data Roaming on or off.

• Android: Open Settings → Connections → Mobile Networks → Toggle Data Roaming on or off.

It’s important to remember to check these settings before you travel and also when you arrive at your destination. Keeping roaming off can prevent you from racking up unnecessary charges, and you can always turn it on if you decide it’s necessary.

Understanding international data plans and packages

International data plans can make roaming a lot more affordable. These packages let you pay a flat fee for data, texts, and calls while you’re abroad, so there are no surprises at the end of your trip. Most mobile providers have options that range from daily passes to month-long data packages.

For example, some providers offer packages that give you a set amount of data per day for a fixed cost. Others may provide a larger data bundle that’s valid for the duration of your trip. Depending on your needs, these plans can be a real money-saver compared to paying per megabyte of data used. It’s worth checking with your provider before you travel to see what options they have.
