Your iPhone works perfectly at home. You have Internet access, you can pay with Apple Pay, look up directions, and open your favorite apps without a second thought. But when you land in another country, you turn off Airplane Mode and discover you don’t have cellular data.
The good news is that you can avoid this situation with a few adjustments before you travel.
You don’t need to be a tech expert to get your phone ready. You just need to understand what can change and check a few settings before you head out on your trip.
In this guide, you’ll learn how to check for eSIM compatibility, set up mobile data, download maps, and prepare your payment methods. You’ll also find solutions to the most common connection issues when using your iPhone in another country.
If you plan to use an eSIM while traveling, the first thing to do is check whether your iPhone is compatible.
Not all models support this technology, and there are differences between devices sold in different regions.
To do an initial check:
Open Settings on your iPhone
Go to General > About
Look for the “Available SIM” section or the information about the device’s SIM and eSIM.
Check to see if an EID (Electronic Identification) associated with eSIM functionality appears
The presence of an EID is a helpful indicator, but it doesn’t guarantee on its own that you’ll be able to activate any plan. You should also consider the model, region, and carrier restrictions.
If you need to check which models support this technology, Holafly’s eSIM phone list can serve as an initial reference. To confirm regional differences, also check Apple’s official specifications.
If you see “No SIM Restrictions,” the iPhone is unlocked.
If something else is listed, check with your carrier before signing up for a plan with another company. Apple cannot directly remove carrier-imposed locks.
What If Your iPhone Doesn’t Support eSIM?
If you find that your iPhone doesn’t support eSIM, that doesn’t mean you have to rely on roaming for the entire trip. You still have other options for connecting to the internet abroad.
The first is to use a physical SIM card from a local carrier, provided your iPhone has a SIM tray and is unlocked. You can buy one when you arrive at your destination or, in some cases, before you travel.
Another option is to check the international plans offered by your usual carrier.
If you’d rather not switch SIM cards or use roaming, you can also connect to Wi-Fi networks available at hotels, airports, and other locations. In that case, it’s a good idea to download maps, reservations, and important documents so you can access them offline.
Step 2: Review Your Cellular Data And Roaming Settings
One of the most common mistakes when traveling is assuming that mobile data will work exactly the same way as it does at home.
Depending on your carrier and your destination, using roaming may result in additional charges. You may also need to activate an international data plan before you leave.
Open Settings
Go to Cellular or Mobile Data, depending on your region
Select the line you want to check, if you have more than one
Go to Cellular Data Options or Mobile Data Options
Check the status of Data Roaming
If you plan to use your regular phone line while abroad, check your plan’s terms and conditions first and enable roaming only when necessary.
If you’ll be using a travel eSIM, follow your provider’s instructions. Some plans require Data Roaming to be enabled on that line in order to connect to a local network.
The important thing is to check which line will be using data and what rates apply.
Step 3: Download Apple Maps For Offline Navigation
You don’t have to wait until you lose service to find out that Maps can’t load a route.
On iPhones running iOS 17 or later, Apple Maps lets you download maps for offline use in regions where this feature is available.
Open Maps
Tap your photo or initials next to the search field
Select Offline Maps
Tap Download New Map
Search for your destination and adjust the area you want to download
Tap Download
It’s best to do this at home or while connected to a stable Wi-Fi network.
Downloaded maps can help you look up directions and get around without using cellular data. However, some features that require real-time information may not be available.
Save Important Addresses Before Traveling
In addition to downloading maps, save the address of your lodging and any other places you’ll need to find when you arrive.
You can do this in Notes or save a screenshot with the full address. It’s also a good idea to check your location permissions:
Open Settings > Privacy & Security
Select Location Services
Make sure the feature is turned on
Open Maps and review its permissions
You don’t need to allow all apps to use your location all the time. Just set the appropriate permissions for the apps you’ll actually be using.
Step 4: Check Apple Pay And Banking Verification Methods
Apple Pay can make shopping easier while traveling, but don’t assume it will work at every store or in every country.
However, before you leave:
Open Wallet and make sure your cards are available.
Check with your bank to see if you can use them internationally.
Find out about any fees for foreign-currency payments.
Bring a physical card or an alternative payment method when necessary.
Remember that using Apple Pay doesn’t automatically waive your card’s international fees.
Make Sure You Can Receive Verification Codes
This is especially important if you plan to use a travel eSIM for mobile data. Some banks send verification codes via SMS to the number registered in your account.
If you deactivate your regular phone line or are unable to receive messages while abroad, you may have trouble confirming a transaction.
Before traveling, log in to your banking apps and check which authentication methods are available to you.
If your bank allows you to confirm transactions via in-app notifications or another secure method, set it up in advance.
Step 5: Update iOS And Download Essential Content
Updating your iPhone while traveling isn’t always a good idea, especially if you have limited data.
That’s why it’s a good idea to check for updates before you leave.
Open Settings > General > Software Update
Check to see if an update is available
If you decide to install it, do so well in advance so you can verify that everything is working properly.
It’s also a good idea to update the apps you’ll be using during your trip. Next, download any content you might need offline: documents, reservations, music, podcasts, or videos.
If you’re running low on storage space, delete files you no longer need or move photos and videos to a secure storage location before you leave.
Prepare Your Battery And Charging Accessories
Long days of travel can really drain your iPhone’s battery. To reduce battery usage when necessary, you can turn on Low Power Mode from Settings > Battery.
It’s also a good idea to check what type of plug is used in the country you’re visiting and bring a compatible adapter if you need one. If you plan to use a portable charger, check your airline’s carry-on regulations before flying.
Your iPhone Is Ready To Travel, But Is It Prepared?
Your iPhone can still be an excellent tool when you travel abroad. What changes isn’t the device itself, but the networks, services, and terms of use you’ll encounter at each destination.
Checking your connectivity, downloading maps, and verifying your payment methods before you leave can save you some pretty annoying problems.
After all, you prepare your passport, reservations, and luggage. Your iPhone also deserves a few minutes of preparation before you take off.
