One thing that catches a lot of first-time international travelers off guard is that moment right after you step off the plane: "Wait, why isn't my phone connecting?" Maps, translation apps, ride-hailing — none of them work without data. This guide walks you through exactly what to do, from the moment you land to the moment your phone is back online, in plain language anyone can follow.
- Once you land, it's three steps: turn off Airplane Mode → switch on your travel eSIM line → turn on data roaming
- Turning on roaming for a travel eSIM is fine — it won't trigger a separate surprise bill
- Enable roaming on the travel eSIM only, and keep your home line off to avoid unexpected charges
- A data-only eSIM can't make number-based calls or receive SMS codes, but app calls like WhatsApp work over data
- Even "unlimited" plans can have speed or tethering conditions, so they aren't truly without limits
The short answer: do these steps in order once you land
There's nothing complicated here. If you installed your eSIM before departure, getting online after you arrive comes down to three basic steps.
- Turn off Airplane Mode (toggling it on and then off again can help your phone grab the local signal)
- Switch on your travel eSIM line (set it as your primary line for mobile data)
- Turn on data roaming for that line
Once the signal bars appear and data starts flowing, you're good to go. If you haven't actually installed your eSIM yet, do it before you leave using our setup guide — that way, all you'll need to do on arrival is switch it on. If you'd like to see how the whole process fits together first, our complete guide to setting up a travel eSIM is a great companion read.
Why knowing the "just landed" steps brings real peace of mind
When you arrive in a new country, the signage and the language around you are unfamiliar, and it's easy to feel rushed. If your phone won't connect on top of that, you end up hunting for Wi-Fi or queuing at a help desk — extra hassle you don't need.
The flip side: if you simply know how to get online right after landing, your phone can have maps and ride-hailing ready by the time you walk out of the arrivals gate. Clearing that first hurdle sets the tone for a calmer trip overall.
Step 1: Turn off Airplane Mode
Most people keep their phone in Airplane Mode during the flight. Once you've landed and you're ready to disembark, the first thing to do is switch Airplane Mode off.
At this point, toggling it on and then off again makes it easier for your phone to reconnect to the local network. It's a handy trick to remember whenever the signal is slow to appear.
Step 2: Switch on your travel eSIM line
Most phones can hold two lines at once — your usual home line (the SIM or eSIM you use day to day) and your travel eSIM. After you arrive, switch the eSIM you'll use locally to be your primary line for mobile data.
On iPhone
Open "Settings" → "Cellular" (or "Mobile Data"), select your travel line (it'll show your plan name or label), turn that line on, and set "Cellular Data" to use it. It's a good idea to switch your home line off here to avoid any unintended data use.
On Android
Go to "Settings" → "Network & internet" → "SIMs" (the wording varies a little by model), choose your travel eSIM, and set it as the line used for mobile data.

Step 3: Turn on data roaming
This is where a lot of people hesitate, because "roaming" sounds like "huge bill." But data roaming on your travel eSIM has to be turned on for that eSIM to work abroad. Turning on roaming for an eSIM you bought for travel simply lets you use it within that plan — it doesn't mean a separate, expensive charge from your home carrier.
The key point: turn roaming on only for the travel eSIM line, and leave your home line's roaming off. That way you stay connected locally while avoiding any unexpected charges.
The whole get-online process in one table
| Order | Action | What to check |
|---|---|---|
| 1 | Turn off Airplane Mode | If nothing connects, toggle it on then off |
| 2 | Switch on the travel eSIM line | Set it as your primary line for data |
| 3 | Turn on data roaming | On the travel eSIM only; home line stays off |
| 4 | Check the signal bars | Seeing a local carrier name means it worked |
| 5 | Test the connection in a browser | Confirm it's live with a maps app or similar |
Once you've ticked off these five, you'll have a working connection before you even leave the airport.
What to try if it won't connect
Even when you follow every step, it doesn't always connect right away. Don't panic — work through these in order.
- Toggle Airplane Mode on then off to grab the signal again
- Confirm the travel eSIM is correctly set as your primary line for data
- Check that data roaming is on for that eSIM
- Restart your phone
- Check your plan's activation timing (some plans only activate once you arrive at your destination)
Right after landing, lots of people connect at once, so waiting a few minutes can help things settle. If it still doesn't improve, our troubleshooting guide covers fixes by symptom. Stay calm and try them one at a time — most issues get resolved right there.
Worth knowing: data-only eSIMs and the fine print on "unlimited"
Bloomy plans are generally data-only. Maps, social media, and app-based calls such as WhatsApp can work wherever you have a data connection, but number-based voice calls and SMS verification codes sent to a phone number are generally not supported. If there are moments where you'll need a phone number, SMS, or voice, it's wise to arrange a backup (such as a local plan that includes a number) as well.
Also, an "unlimited" plan doesn't mean "use as much as you want with no limits whatsoever." Plans may include a fair-use policy, reduced speeds after a certain amount of data, conditions on tethering, and so on. Real-world speeds also depend on the local network, the area you're in, your device, and congestion at busy times. Checking the latest plan conditions before you buy helps avoid surprises after you arrive.
A little prep before departure makes arrival much easier
The trick to keeping on-arrival steps to a minimum is to finish your prep before you leave.
- Install the eSIM (scan the QR code) while you still have Wi-Fi before departure
- Confirm your device supports eSIM and is carrier-unlocked
- Install the apps you use often — maps, translation, ride-hailing
- Know your plan's activation timing, data allowance, and number of days
With installation done in advance, all that's left at the airport is "turn off Airplane Mode → switch on the line → turn on roaming." Our setup guide walks you through the detailed steps with screenshots.
What you can do with Bloomy
If your destination and trip length are set, you can browse plans by country, data amount, and number of days on our eSIM comparison page. Pick just what you need — a smaller allowance for a short trip, something more generous for a long stay.
After purchase, you can check your eSIM's remaining data and QR code anytime in My Account, so if you ever wonder "how much do I have left?" while traveling, you can calmly take a look. Plan details and pricing are shown in USD and may change, so please confirm the latest details at the time of purchase.
The on-arrival steps are genuinely simple once you've got them down. Install your eSIM before departure, then it's just three steps at the airport. That's all it takes to make your phone a reliable travel companion, even on your first trip abroad. For any finer questions, our FAQ is there to help.
