Using a Travel eSIM Alongside Your Home SIM: How to Switch Your Settings Back After Your Trip

Last updated: September 12, 2026

If you kept your home-country SIM active while using a travel eSIM abroad, you may find yourself wondering after landing: "Will my regular line work again?" and "Is it safe to delete the travel eSIM?" Plenty of guides walk you through setup before departure, but far fewer explain how to switch everything back afterward. This article covers what to do in the first few minutes after landing, the step-by-step process for both iPhone and Android, and how to tidy up your travel eSIM. The short version: the one thing you really need to change is switching mobile data back to your home carrier's line. Data roaming can stay off while you're at home.

The one setting that matters: which line handles mobile data

Of everything you set up before departure, the only change you really need to undo is switching mobile data from the travel eSIM back to your home carrier's line. In our pre-departure setup guide, we explained how to turn off data roaming on your home line and route mobile data through the travel eSIM. Coming home is roughly the reverse, but you don't need to reverse every single step.

For example, data roaming on your home line can stay off as long as you're using it in your home country. Domestic connections don't count as roaming, so you'll connect normally with it disabled. Leaving it off also means one less thing to remember before your next trip.

From landing to home: the order to follow

Right after you step off the plane, simply turning off airplane mode may leave mobile data still routed through the travel eSIM. Because most travel eSIM plans don't cover your home country, this can look like "I have signal bars but nothing loads." No need to panic. Just follow these steps in order:

1. Turn off airplane mode: Give your home line 30 seconds or so to pick up a local signal.
2. Switch mobile data back to your home carrier's line: This is the most important step. The exact taps are covered in the next section.
3. Open any web page in your browser: If it loads over your home line, you're essentially done.
4. Turn off the travel eSIM line: There's no need to rush and delete it at the airport. You can decide later, once you've settled in.

One thing to watch out for: if you're connected to airport Wi-Fi, you may not notice that mobile data hasn't switched back. Turn Wi-Fi off briefly and confirm that a page loads over mobile data alone.

How to switch back on iPhone

On iPhone, go to Settings → Cellular (or Mobile Data, depending on your region) and check these three things. Labels may differ slightly depending on your iOS version.

1. Set mobile data back to your home line

On the Cellular screen, tap Cellular Data and select your home carrier's line (using whatever label you gave it before departure). If you turned off Allow Cellular Data Switching before your trip, you can leave it off. With it disabled, your phone won't switch to the travel eSIM on its own.

2. Turn off the travel eSIM line

On the Cellular screen, tap the travel eSIM's line name and toggle off Turn On This Line. Turning off the line keeps the profile on your device, so you can decide later whether to delete it.

3. Check the status of your home line

Tap your home carrier's line and confirm that Turn On This Line is enabled and Data Roaming is still off. Roaming can stay off while you're at home. If the signal indicator at the top of the screen shows your home line, you're ready to go.

How to switch back on Android

On Android, menu names vary by manufacturer and model. On most devices, you'll find these settings under Settings → Network & internet → SIMs (or Mobile network / SIM manager on some models).

1. Set your home line as the preferred SIM for mobile data: Under Mobile data or SIM for data, select your home carrier's line.
2. Turn off the travel eSIM: Open the travel eSIM's line and toggle off the Use SIM (or similar) option.
3. Confirm roaming is still off on your home line: You don't need to enable it to connect normally at home.

If you can't find a specific menu, searching your manufacturer's support site for "dual SIM" or "eSIM" usually leads to model-specific instructions.

Post-trip checklist: what to check and what to do

Item	State after landing	Action
Line used for mobile data	Still set to travel eSIM	Switch back to your home line (top priority)
Data roaming on your home line	Off	Leave as is (no roaming needed at home)
Travel eSIM line	Still on	Turn it off; decide about deleting later
Allow Cellular Data Switching (iPhone)	Off	Leave as is
Default voice line	Home line	No change needed
Wi-Fi	Connected to airport Wi-Fi	Turn off briefly and test over mobile data

As the table shows, only one or two items actually need attention. To avoid the classic "I forgot to switch back and didn't notice until the next day," test that a page loads over mobile data alone before the day is out.

Should you delete the travel eSIM or keep it?

Whether to remove a used travel eSIM profile is easiest to decide based on your upcoming travel plans. Bloomy eSIM plans are prepaid at the time of purchase, so leaving an expired profile on your device doesn't generate any charges on its own.

You may prefer to delete it if…

• You have no plans to visit the same destination soon and want a tidy list of lines
• You have several travel eSIMs installed and it's getting hard to tell which is which
• You already know your next trip will use a different country or plan

It's fine to keep it if…

• You're heading back to the same destination soon and your plan still has data and validity remaining
• You don't mind it sitting there turned off (a disabled line won't connect or switch on its own)
• You're not confident about the deletion steps and would rather check calmly before deciding

To delete, use Delete eSIM at the bottom of the line's screen on iPhone, or Erase SIM (or similar) within the line's settings on Android. A deleted profile can't be restored on the device, so if a plan still has remaining data or validity, check its status in My Account before you decide.

If your home line won't connect: what to check, in order

The most common reason your home line "won't load anything" after a trip is the one covered above: mobile data is still routed through the travel eSIM. If switching it back doesn't help, work through this list from the top.

1. Toggle airplane mode on and off again: This prompts your phone to reconnect to the local network.
2. Is your home line turned on? If you disabled the entire line before departure, turn it back on.
3. Is mobile data set to your home line? Double-check which line name is selected.
4. Are your carrier's APN settings still in place? If your carrier requires a manual APN or configuration profile and it was removed, data won't work. Check your carrier's official instructions for the correct values.
5. Restart your device: This often helps when a line switch hasn't taken effect right away.
6. Check your remaining data with your home carrier: With data roaming off during your trip, your home allowance shouldn't have been used, but it's worth a quick look in your carrier's app or account page just to be sure.

For issues on the travel eSIM side (couldn't connect abroad, data ran down faster than expected, and so on), see our troubleshooting guide. If you contact support after your trip, noting when, in which country, and what your phone displayed will make things much quicker to sort out.

What about calls and texts on your home number?

Because travel eSIMs are data-only, calls and SMS on your regular phone number were handled by your home line throughout your trip. Nothing changes after you return: calls and texts on your home line work normally at home. On the travel eSIM side, app-based calling (WhatsApp, Messenger, FaceTime, and similar services that run over data) worked as usual while you were away — the only things not available on it were traditional voice calls and SMS tied to a phone number.

If you received calls to your home number while abroad, your home carrier may have applied international roaming charges depending on your plan's terms. Coverage and rates vary by plan, so check your carrier's latest information or your bill if you want to be sure.

For your next trip: keep the routine

Once you've been through this cycle, the routine sticks: switch lines before departure, switch back after landing. The pre-departure steps are covered in Using a Travel eSIM Alongside Your Home SIM: Settings to Sort Out Before You Leave, so next time you can have everything ready in about five minutes with that page open.

Once your next destination is set, browse the Bloomy eSIM comparison page to find a plan by country, data amount, and trip length. Setup is straightforward — tap the setup link you receive, follow the on-screen prompts to add the eSIM, then turn the line on when you arrive — so you can take care of it whenever you have a spare moment before departure. And if this trip left you thinking "I could have used a bit more data" or "I had days left over," that's useful input for choosing your next plan.

Summary: just three things to do after you land

• Switch mobile data back to your home carrier's line (top priority)
• Turn off the travel eSIM line; decide whether to delete it based on your next trip
• Turn off Wi-Fi briefly and confirm a page loads over mobile data

Your data roaming and voice line settings can stay as they were before departure, so you're really only touching one or two things. Once that's done, your home line is back to normal. If anything is unclear, take a look at our FAQ as well.
