What is Data Roaming? Your Guide to On, Off & Costs
The Definition of Data Roaming
Ever wondered what “data roaming” really means when it pops up on your phone’s screen? Put simply, data roaming is what happens when your mobile phone uses the internet by connecting to a network that isn’t its own. Your phone is essentially a guest on another provider’s network. This allows you to stay connected to the internet for browsing, emails, and using your favourite travel apps, even when you’re away from your usual coverage area.
This typically occurs in two main situations. The most common is international roaming, which happens when you travel overseas and your phone connects to a local carrier in that country. It can also happen within Australia in what’s called domestic roaming. This is when you’re in a remote or rural area where your provider has no reception, so your phone ‘borrows’ signal from a partner network to keep you online.
Summary
This guide explains everything you need to know about data roaming. You’ll learn exactly what it is, when you should turn it on or off to avoid surprise bills, and how to control the setting on your iPhone or Android. We’ll also cover the difference between using it in Australia versus overseas and answer your most common questions about costs and usage.
TLDR
- What it is: Data roaming is when your phone uses another company’s network to access the internet.
- When to turn it OFF: Turn it off when travelling overseas without a travel plan to avoid expensive charges.
- When to turn it ON: Turn it on if you’ve bought a travel pack or need emergency internet access and are okay with the cost.
- Wi-Fi is different: You don’t need data roaming on to use Wi-Fi.

Should Data Roaming Be On or Off?
Deciding whether to leave data roaming on or off comes down to one key factor: avoiding unexpected costs. That little switch in your settings controls whether your phone is allowed to rack up charges on another network, so it’s crucial to know when to use it.
- Turn it OFF to be safe. The golden rule is to keep data roaming switched off by default, especially when you’re about to travel internationally. This is the single best way to prevent “bill shock”—a massive, unexpected phone bill from your phone using expensive overseas data in the background. If you want to be extra safe, managing your mobile data abroad starts with this simple step.
- Turn it ON when you have a plan. You should only turn data roaming on when you’ve prepared for it. This could mean you’ve purchased a specific travel pass or international roaming pack from your Aussie telco, or your plan explicitly includes roaming for the country you’re visiting. It’s also okay to turn on briefly if you have an emergency and are willing to accept the pay-as-you-go charges.
How to Turn Data Roaming On or Off
Controlling your data roaming settings is simple, but the steps can vary slightly depending on your device. Here’s a quick guide to finding the on/off switch on the most popular smartphones in Australia.
📱 Settings for iPhone
For Apple users, finding the data roaming toggle is straightforward:
- Open the Settings app.
- Tap on Mobile.
- Select Mobile Data Options.
- You will see a toggle switch for Data Roaming. If the switch is green, it’s on. If it’s grey, it’s off.
🤖 Settings for Android
On Android devices like Samsung or Google Pixel, the path is similar:
- Open your phone’s Settings app.
- Tap on Network & Internet (or Connections on Samsung).
- Select Mobile Network or SIMs.
- Find the Roaming toggle switch and turn it on or off.
Note: Menus on Android phones can vary slightly between brands, but the setting is almost always found within your Mobile Network options.
Data Roaming Meaning in Regional Languages
For many non-native English speakers in Australia, understanding telco terms can be tricky. Here’s how “Data Roaming” is commonly referred to or understood in several languages.
| Language | Meaning / Common Terminology |
|---|---|
| Hindi | Often called “रोमिंग” (roaming) or described as “दूसरे नेटवर्क पर इंटरनेट” (internet on another network). The term “Data Roaming” is also widely understood. |
| Urdu | Referred to as “ڈیٹا رومنگ” (Data Roaming) or simply roaming. |
| Bengali | Known as “ডেটা রোমিং” (Data Roaming), the English term is commonly used. |
| Tamil | The term is “டேட்டா ரோமிங்” (Data Roaming). |
| Telugu | Referred to as “డేటా రోమింగ్” (Data Roaming). |
| Kannada | Known as “ಡೇಟಾ ರೋಮಿಂಗ್” (Data Roaming). |
| Malayalam | The term is “ഡാറ്റാ റോമിംഗ്” (Data Roaming). |
| Marathi | Commonly called “डेटा रोमिंग” (Data Roaming). |
International Roaming vs. Domestic Roaming
While both involve using a partner network, the cost and context are very different. Understanding this distinction is key to managing your mobile plan effectively.
🇦🇺 Domestic Roaming
This is when your phone connects to a different network within Australia. It’s common in remote areas like the Outback, where your provider (e.g., Optus) might partner with another (e.g., Telstra) to provide coverage. For most Aussies on major plans, domestic roaming is usually included at no extra cost.
🌍 International Roaming
This occurs when you travel outside of Australia and your phone connects to a foreign network (like AT&T in the US or Three in the UK). This service almost always incurs significant extra costs unless you have purchased a specific travel pack or your plan has a special international roaming inclusion.
Frequently Asked Questions (FAQ)
What is the difference between mobile data and data roaming?
Mobile data is the internet service you use when you’re connected to your own provider’s network (e.g., Telstra, Optus, Vodafone) within Australia. Data roaming is when you use internet data on a different, or “guest,” network, either overseas or in a part of Australia your provider doesn’t cover.
Does data roaming cost extra money?
Generally, yes, especially for international roaming. It can be very expensive. Some premium mobile plans might include “roam like at home” benefits for specific countries (like New Zealand), but for most destinations, you’ll pay high per-megabyte rates unless you buy a travel pass. A great alternative to avoid these costs is to use local prepaid services when you arrive at your destination.
Do I need data roaming on for Wi-Fi?
No, you do not. Wi-Fi is a completely separate technology from the mobile network. You can safely turn off both your mobile data and data roaming and still connect to and use any Wi-Fi network at your hotel, a café, or the airport. For peace of mind, many travellers turn on Flight Mode and then manually re-enable Wi-Fi.
What happens if I accidentally leave data roaming on?
If you leave data roaming on while overseas, your phone might connect to a local network and start using data without you actively doing anything. Background processes like automatic app updates, email syncing, and social media notifications can consume data quickly, potentially leading to hundreds of dollars in charges from your telco.
Does receiving text messages count as data roaming?
This is a great question with a two-part answer. Receiving standard SMS text messages usually doesn’t count as data roaming and is often free, as they use the older voice network. However, sending an SMS from overseas will likely incur a small charge. Crucially, messages sent via apps like iMessage, WhatsApp, and Facebook Messenger do use data. If you are not on Wi-Fi, you will need data roaming enabled (and will be charged for the data) to send or receive these types of messages.
