The seatbelt sign goes off, and the first thing most people do is switch airplane mode off. Abroad, though, the moment you do that your phone starts hunting for a local network — and if it finds one, it will happily carry on as if you were still at home. This article walks through the order of operations between landing and leaving the airport. The short version: don't turn airplane mode off right away. Leave it on, switch off data roaming on your regular line, set your travel eSIM as the line you'll use for data, and only then turn airplane mode off. That sequence makes unintended connections far less likely.
- Don't switch airplane mode off the second you land
- Turn data roaming off first
- Switch your data line over to the eSIM
- Turn airplane mode off last, then check
- If nothing loads, check which line is selected
What's actually happening inside your phone when you land
Turn airplane mode off and your phone automatically looks for whatever network it can reach and connects. If data roaming is still switched on for your home-country line, it may latch onto a local partner network — and from that point on, everything works as usual, at roaming rates.
The tricky part is that data moves even when you're not touching the phone. App updates, photo and file sync to the cloud, mail fetching, maps refreshing your location — all of that can run while the screen is off in your pocket. Spending a few minutes at the baggage carousel and finding that far more data went through than you expected is a very common story.
That's exactly why the order matters. For the bigger picture — what happens if you simply keep using your phone abroad, how the charges work, and what your connectivity options are — see Using your phone abroad without changing anything: the settings and options that keep the bill down. This article zooms in on just one part of that: the first few minutes after arrival.
After you land: four steps
Here's the flow in one line: get everything set up while airplane mode is still on, and turn airplane mode off at the very end. Decide the order in advance and you won't have to think about it in the rush of arrival.
Step 1: Leave airplane mode on
Don't switch it off when the wheels touch down. While airplane mode is on, your phone won't connect to any cellular network, which gives you a calm moment to open your settings. Watching everyone around you reconnect can be hard to resist, but a few minutes' delay almost never costs you anything.
Step 2: Turn off data roaming on your home-country line
In settings, find the line you normally use (your primary line) and switch data roaming off. With that off, that line is much less likely to start pulling data abroad once airplane mode goes away. On dual-SIM phones each line has its own settings, so keep an eye on which line you're actually editing.
Step 3: Switch your data line to the travel eSIM
If you installed an eSIM before your trip, turn that line on and set it as the line used for mobile data. You can toggle lines on and off and change which one handles data even while airplane mode is on. If your phone has a setting like "allow cellular data switching" — which quietly falls back to another line when one can't connect — turning it off helps keep the wrong line from being used.
Step 4: Turn airplane mode off and check your connection
Now, finally, switch airplane mode off. When a local operator name appears at the top of the screen and a browser page or app loads, you're set. It doesn't always happen instantly, so give it a minute or two — or toggle airplane mode on and back off, which often nudges the phone into registering.
The names and locations of these settings vary by manufacturer, model, and OS version. If you can't find the exact wording used here, try the search box inside Settings with terms like "roaming" or "mobile" / "cellular".
Where to find these settings on iPhone vs. Android
The steps are the same; only the route there differs. Use the table below as a rough guide (typical wording as of August 2026 — labels differ between models).
| What you want to do | On iPhone (typical) | On Android (typical) |
|---|---|---|
| Open the list of lines | Settings → Cellular | Settings → Network & internet → SIMs |
| Turn off data roaming | Select the line → Data Roaming | Select the SIM → Roaming |
| Change which line is used for data | Cellular Data → choose the line | Mobile data → choose the SIM |
| Add an eSIM | Settings → Cellular → Add eSIM | Settings → Network & internet → Add SIM |
| Check data usage | Bottom of the Cellular screen | The Data usage screen |
If the details on your screen don't quite match, the setup guide walks through the steps.
If you're using an eSIM, do this before you leave
The fastest way to make arrival simple is to finish the setup before you travel. Installing an eSIM needs an internet connection, so doing it on Wi-Fi at home leaves you with nothing to do on landing but flip a switch.
- Check that your phone supports it: use the device compatibility checker to confirm eSIM support and whether your phone is carrier-locked.
- Pick a plan by destination, data amount and length of stay: how much data you need depends on how long you're there and whether you'll mostly use maps, search and messaging or also stream video.
- Install it with one tap from the link you receive: with Bloomy eSIM you tap the setup link you're sent and follow the on-screen prompts. Leave the line switched off afterwards and turn it on when you arrive — that keeps things tidy.
- Check when the plan starts counting: activation works differently from plan to plan, so read the details shown at purchase.
One important note: Bloomy eSIM plans are data-only. App-based calls that run over data — WhatsApp, Messenger, FaceTime and the like — work as usual, but there is no phone number, so calls and SMS to and from a number aren't included. Plans are also subject to a fair usage policy. If you'll need a number or SMS while you're away, plan for it separately: keep your home-country line able to receive calls and texts, or look at a local SIM or a plan that comes with a number.

What to check when you can't get online after landing
Most of the time it's one of two things: the wrong line is selected for data, or the phone hasn't re-registered on a network yet. Before you start changing settings at random, work through these in order — it's much easier to undo.
| Symptom | What to check | What to try |
|---|---|---|
| No service, and it stays that way | Airplane mode / whether the line is on | Turn airplane mode on, wait about ten seconds, turn it off again |
| Signal bars, but nothing loads | Which line is used for mobile data | Confirm the eSIM is the one selected |
| The eSIM line isn't in the list | Whether the eSIM installed successfully | Connect to Wi-Fi and install it again |
| Connection drops now and then | Where you are and what time it is | Step outside or near a window and wait a moment; try again later |
| Restarting the phone doesn't help | Plan status and your settings | Review the details from your purchase and the support pages |
Speed and reliability depend on the local networks, your device, the area you're in and how busy the network is at that hour. Arrival halls and underground levels are often weak spots, so moving somewhere else before you judge is worth a try. If it still won't work, the troubleshooting page has step-by-step checks for each situation.
Who this approach suits — and who should plan for more
It suits you if your trip runs on data. Maps, translation, search, messaging apps, sharing photos — for all of that, switching to an eSIM after you land is plenty.
- A good fit: short trips or business travel where maps, search and app-based calls cover everything / first-time travellers who want the setup done before departure / anyone getting family or travel companions ready at the same time
- Worth planning further: if you need to receive calls or texts sent to your home-country number while abroad / if you'll need SMS verification codes from your bank back home or other services / if work calls may come through to your number
In those cases, a common approach is to split the roles: data on the eSIM, calls to your number on your home-country line. Be aware that leaving that line active to receive calls can incur charges abroad depending on your contract, so check the current terms from your home carrier before you decide.
A few situations worth thinking through
If you have a connecting flight, remember that turning airplane mode off at the transit airport can connect you to that country's networks too. If you don't need to be online there, staying in airplane mode or using the airport Wi-Fi is the simpler choice. It's also worth checking before you buy whether your travel eSIM covers the transit country.
Family members' and children's phones are easier to sort out together before departure, since they won't be adjusting settings themselves. Switching data roaming off and setting app updates to "Wi-Fi only" are both easy wins to handle in advance.
On the flight home and after you get back, use the same logic in reverse: while still in airplane mode, switch your home line back on and turn the eSIM line off, then leave airplane mode. Nothing gets missed that way. Checking your bill a little while after you return also means you can query anything unexpected early.
In short: decide the order, and arrival gets easy
Boiled down, there are only four things to do when you land. Stay in airplane mode, switch data roaming off on your home line, set the eSIM as your data line, and turn airplane mode off last. Jot that down, or run through it once before you leave, and a lot of the arrival-day anxiety goes away.
If you haven't yet decided how you'll get online abroad in the first place, start with Using your phone abroad without changing anything: the settings and options that keep the bill down and work forward from there. Other questions are covered in the FAQ and the eSIM guide.
