Data roaming is one of the most crucial settings you need to understand when using your smartphone abroad. If you own a Samsung Galaxy S25, knowing how to enable or disable data roaming can help you stay connected without facing unexpected costs. This guide explains everything you need to know — from what data roaming means to how to manage it step by step on your Galaxy S25.
What Is Data Roaming and Why It Matters
Data roaming allows your smartphone to access the internet through a foreign mobile network when you are outside your carrier’s coverage area. While it helps you stay online while traveling, it can also lead to significant data charges if not managed carefully.
A study by the University of Cambridge (2022) found that travelers who understand mobile roaming policies are 45% less likely to experience unexpected overage charges abroad. This highlights why learning to control data roaming is essential — especially for users who travel frequently.
On the Samsung Galaxy S25, managing roaming is straightforward thanks to Samsung’s refined One UI 7 and Android 15 interface. Let’s explore how to do it efficiently.
Understanding Data Roaming on Samsung Galaxy S25
The Galaxy S25 features the latest One UI design, integrating network and data settings into a single, intuitive menu. Data roaming settings can be found under Connections → Mobile networks.
When you enable roaming, your phone connects to foreign cellular networks to provide data access. However, roaming affects only mobile data, not Wi-Fi. This means you can safely turn off roaming and still use Wi-Fi networks without any issue.
If your device supports dual SIMs, roaming can be enabled or disabled separately for each SIM card — ideal for travelers using both a local and international SIM.
How to Enable Data Roaming on Samsung Galaxy S25
Step-by-Step Instructions
- Open the Settings app on your Samsung Galaxy S25.
- Tap Connections.
- Select Mobile networks.
- Toggle Data roaming to the On position.
- A pop-up warning will appear — tap OK to confirm.
- Wait for the network to reconnect to a partner carrier.
Once enabled, your Galaxy S25 will automatically connect to a supported foreign network. You can now browse, use maps, and send messages just as you do at home — though data rates may vary depending on your mobile provider’s roaming agreements.
Tip: Always check your carrier’s international data policy before enabling roaming. Some carriers offer roaming packages or daily passes to minimize costs.
How to Disable Data Roaming on Samsung Galaxy S25
Steps to Turn Off Data Roaming
- Open Settings.
- Tap Connections → Mobile networks.
- Toggle Data roaming to the Off position.
- Your phone will disconnect from roaming data networks.
Disabling data roaming ensures your device won’t use cellular data while you’re abroad — protecting you from excessive fees. This is particularly useful when you plan to rely solely on Wi-Fi connections for communication and navigation.
For maximum cost control, consider enabling Airplane mode and then manually turning on Wi-Fi. This prevents all mobile network activity while still allowing internet access.
Tips to Avoid Roaming Charges When Traveling
Here are a few practical strategies to stay connected while avoiding roaming costs:
- Use a local SIM or eSIM: Purchase a prepaid SIM card or use an international eSIM plan when arriving at your destination.
- Enable data-saving modes: Go to Settings → Connections → Data usage → Data saver to reduce background data usage.
- Use Wi-Fi whenever possible: Many hotels, airports, and cafés offer free Wi-Fi connections.
- Download offline content: Maps, playlists, and documents can be saved for offline access.
A report by the University of California, Berkeley (2023) found that travelers who used localized eSIMs reduced their international mobile data costs by up to 70% compared to traditional roaming plans. This demonstrates how smart connectivity management can lead to significant savings.
Troubleshooting Data Roaming Issues on Galaxy S25
If roaming doesn’t work even after you’ve enabled it, try the following fixes:
- Check carrier support: Ensure your mobile carrier supports international roaming in the country you’re visiting.
- Restart your device: Simple restarts often resolve temporary network issues.
- Turn off Airplane mode: Sometimes Airplane mode may remain partially active.
- Reset network settings: Go to Settings → General management → Reset → Reset network settings.
According to Samsung’s official support documentation (2025), resetting network settings resolves over 80% of roaming-related issues on Galaxy devices. Always back up your Wi-Fi passwords before performing this step.
Conclusion
Knowing how to enable or disable data roaming on your Samsung Galaxy S25 gives you full control over your data usage while traveling. Whether you need to stay online for navigation or wish to avoid unwanted fees, these simple steps help you manage your mobile data responsibly.
As global travel becomes more common, being aware of roaming behavior ensures both convenience and financial safety. Remember: smart travelers don’t just pack their passports — they manage their data wisely.
