How to Turn Off Data Roaming on iPhone
Traveling abroad and want to avoid expensive roaming charges? On iPhone, a few simple settings can help you control mobile data, prevent surprise fees, and use a travel eSIM only when you need it.
Data roaming charges can add up quickly when you travel. Your iPhone may connect to a foreign mobile network as soon as you land, and some apps can use mobile data in the background without you noticing.
Email, weather updates, notifications, maps, messages, app refreshes and cloud services can all use data. That is why many travelers prefer to turn off roaming on their main line and use a prepaid travel eSIM for mobile internet abroad.
What Is Data Roaming on iPhone?
Data roaming allows your iPhone to use mobile networks outside your regular carrier’s home network. For example, if you normally use a Canadian mobile carrier and travel to the United States, Mexico or Europe, your iPhone may connect to a partner network abroad.
This can be convenient, but it may also create extra charges depending on your mobile plan.
How to Turn Off Data Roaming on iPhone
These steps work on most recent iPhone models. The wording may vary slightly depending on your iOS version.
Open Settings
On your iPhone, open the Settings app.
Tap Cellular
Tap Cellular or Mobile Data, depending on your region and iOS language.
Select Your Main Line
If you use more than one line, choose your regular phone plan, such as your Canadian carrier line.
Open Cellular Data Options
Tap Cellular Data Options or Mobile Data Options.
Turn Off Data Roaming
Disable Data Roaming. Your iPhone will avoid using roaming data on that line while traveling.
The Most Important Setting Before You Travel
Before flying, check that data roaming is turned off on your main phone line. You can then install your VoyageSIM travel eSIM while connected to Wi-Fi and activate it once you arrive at your destination.
How to Use a Travel eSIM Instead of Roaming
A travel eSIM does not necessarily replace your main phone number. It adds a separate mobile data plan for your destination. This allows you to keep your regular SIM active while using your eSIM for internet abroad.
Recommended Travel Setup
Use your VoyageSIM eSIM as your mobile data line while keeping data roaming disabled on your main carrier line. This helps reduce the risk of unexpected roaming fees.
When Should You Turn Off Data Roaming?
Ideally, turn off data roaming before you leave. This helps prevent your iPhone from automatically using a foreign network when you land.
You should also check this setting when returning from a trip, changing SIM cards, activating an eSIM, or using more than one cellular line on your iPhone.
Which iPhones Support eSIM?
Most recent iPhones support eSIM technology, including iPhone XS, iPhone XS Max, iPhone XR and newer models. This includes iPhone 11, 12, 13, 14, 15 and 16 series, depending on the country where the device was purchased.
Quick Compatibility Tip
On iPhone, go to Settings > Cellular. If you see an option such as Add eSIM or Add Cellular Plan, your device is likely eSIM compatible.
Can You Still Receive Calls and Texts?
Most travel eSIM plans are designed for mobile data. They let you use internet-based apps such as WhatsApp, Messenger, FaceTime, iMessage, email, maps and travel apps.
Traditional calls and SMS depend on your main line and your carrier. To avoid extra fees, many travelers use apps like WhatsApp, Messenger, FaceTime Audio or iMessage over mobile data or Wi-Fi.
