Phone without eSIM? How to get mobile data when you travel

No eSIM in your phone? How to make sure, and how to get data abroad anyway: a local SIM, roaming, a pocket router, a second phone with eSIM or an adapter and its limits.

If your phone doesn’t support eSIM, you can’t install a travel eSIM profile on it directly, but you can still get mobile data on your trip: through a local SIM, your home carrier’s roaming, a pocket router or a second phone with eSIM used as a hotspot. Another route is an eSIM adapter, often called a “physical eSIM”: a plastic SIM card you load eSIM profiles onto. The adapter has limits, so it isn’t for everyone.

Does my phone really not support eSIM? How to check

You can confirm your phone has no eSIM in a minute: dial *#06# and look for an EID, then check Settings for an add-eSIM option. Sometimes the eSIM module is there and the option is just tucked away in a menu under another name, such as “Add cellular plan” or “Add mobile plan.”

1. Dial *#06# and see whether an EID shows up among the numbers.
2. Type “eSIM” into the search bar in Settings.
3. Open the SIM or Cellular / Mobile network section and look for an option to add an eSIM or a mobile plan.
4. Run your model through the compatibility check in the Telegram bot @moresim_bot.

The same phone model can differ between the versions sold in different markets: some have built-in eSIM, others have a second plastic SIM slot instead. If your phone came from a carrier abroad, it may have eSIM but only accept that carrier’s profiles. That’s a separate case, covered in our article on carrier-locked phones.

What is an eSIM adapter, or “physical eSIM”?

An eSIM adapter is a plastic SIM card with a rewritable eUICC chip, the same kind of chip that eSIM phones have built in. On a regular SIM card, the carrier profile is written once at the factory. On an eSIM adapter’s chip, you can download, switch and delete eSIM profiles. The card goes into a standard SIM slot, and the phone sees it as an ordinary SIM.

You don’t load eSIM profiles onto an adapter through your phone’s settings but through the adapter maker’s app. The app talks to the card over the phone’s own NFC, or through a separate Bluetooth reader if the phone has no NFC or the app doesn’t support it. Examples of such products are 9eSIM and eSIM.me; each has its own terms, compatibility list and setup process, so read up on the maker’s website.

An adapter helps people whose phones lack eSIM but who want to use travel eSIMs — though not in every case, because it comes with several limitations. So before you buy one, compare it with the options that need no extra card, covered below.

What are the limitations of an eSIM adapter?

An eSIM adapter only works when three things line up: the app supports your platform, the profile is allowed on an adapter, and your phone has a free SIM slot. If any of those is missing, the adapter won’t help.

• The app has to support your platform. Android is usually easier to work with; on iPhone, what you can do with such a card is limited, so ask the maker what exactly works on iOS before you buy.
• Not every eSIM profile installs on an adapter. Some carriers and sellers lock a profile to the device, and it may not install on an adapter or may not work there.
• The adapter takes up a SIM slot. If your phone has only one slot, you’ll have to take out your home SIM, or move your home carrier’s eSIM profile onto the adapter in advance if your carrier allows it.
• You switch profiles in the app, not in the phone’s usual SIM menu. It’s an extra step worth remembering on the road.
• If a profile is locked to the device and has already been downloaded, you usually can’t reinstall it with the same QR code.

How to install an eSIM on an adapter: the general steps

Installing a profile on an eSIM adapter works roughly the same way across makers, but the exact steps depend on the app. Treat the list below as a rough guide and follow the instructions for your adapter.

1. Ask the plan’s seller whether the profile can go on an adapter.
2. Install the adapter maker’s app for your platform.
3. Insert the adapter into the SIM slot, or hold it to the phone over NFC if the instructions say so.
4. Connect to stable Wi-Fi: the profile downloads over the internet.
5. Add the profile in the app using the QR code or activation code.
6. Set the profile as active and wait for the phone to pick up a network.
7. On your trip, turn on data roaming for this line: most travel eSIMs connect to a local carrier as a roaming network, and without it you won’t get online.

No eSIM? Other ways to get mobile data abroad

If an eSIM adapter isn’t right for you, there are four other ways to get data on your trip: a local SIM card, roaming, a pocket router and a second phone used as a hotspot. Each one solves the problem differently, and the best choice depends on the trip.

• Local SIM card: bought on arrival at the airport or a carrier store. Some countries require a passport and registration, and if your phone has one slot, your home SIM has to come out for a while.
• Your home carrier’s roaming: nothing to change, and your number stays reachable. Check the terms and cost with your carrier before you fly.
• Pocket router with a SIM: a separate device shares Wi-Fi with your phone and your travel companions. You need to keep it charged and remember not to leave it in the hotel room.
• A second phone or an old iPhone with eSIM as a hotspot: the travel eSIM goes on that phone, and the phone without eSIM connects over Wi-Fi. If sharing doesn’t work, see our article on using an eSIM as a hotspot.

Which option is right for your trip?

For a short trip without extra gadgets, roaming or a local SIM is usually the easiest fix for a phone without eSIM. If someone in your family or group has an eSIM phone, it’s simpler to put the travel plan on that phone and share the connection with everyone else.

• Need your home number reachable for bank codes? Go with roaming, an adapter in a dual-slot phone, or a second phone as a hotspot.
• Travel often and for long stretches? An adapter, or a new phone with built-in eSIM, may be worth a look.
• Traveling as a group with a laptop and a tablet? A router or a host phone with eSIM is the handy choice.
• Shopping for a new phone anyway? Our article on eSIM-compatible phones lists models and ways to check.

MoreSim plans are data-only, with no phone number. You can call through messaging apps where they aren’t restricted, and texts from your bank still reach your home SIM. If you put the eSIM on a second phone or an eSIM router, the plan starts counting from its first connection in your destination, so you can install it at home ahead of time.
