The quick solution to recover your PilloFon eSIM
If your PilloFon eSIM has no signal, the solution is almost never to reinstall the profile from scratch. First, restart your phone in airplane mode for a few seconds: this forces the phone to reconnect to the network. Then, check that the line is still active and that mobile data is turned on for that particular eSIM.
Most cases of "eSIM no service" fall into one of five causes, and it is best to check them in this order because this is how they are resolved fastest:
| Cause | How frequent | What to do |
|---|---|---|
| Airplane mode activated or mobile data off for that line | Most frequent | See Step 1 |
| Plan or line expired | Very frequent | See Step 2 |
| eSIM profile deleted (phone change, factory reset) | Frequent | See Step 3 |
| Incorrect APN or data settings | Less frequent | See Step 4 |
| Phone is not compatible or has factory-locked eSIM | Infrequent | See Step 5 |
Follow the steps in that order. You don't need to do all five: as soon as the line shows signal again, you can stop there.
Step 1: Restart your phone in airplane mode
Activate airplane mode, wait a few seconds, and then deactivate it. This does not delete or uninstall anything: your eSIM profile is stored on a separate chip from the operating system (the eUICC), so a restart does not affect it. The only thing that is reset is the active connection with the network tower, which is precisely what often fails after a flight, a zone change, or several hours without signal.
If you have two active lines on the same phone (physical SIM plus eSIM, or two eSIMs), also check that mobile data is assigned to the correct line. On phones with dual lines, each has its own data and roaming switch, and it's easy for one to be off without you realizing it after a system update.
If after restarting the line still has no service, the problem is probably not with the phone's configuration but with the account or the network, so move on to the next step.
Step 2: Confirm your line is still active (including Dua line)
Whatever the name of your plan or line —including a line identified as "Dua"—, the mechanism behind an eSIM that stops providing service is usually the same: if the payment cycle expired, the plan was canceled, or the balance ran out, the network cuts off service even if the eSIM profile is still installed on the phone. The phone may continue to show the line's name in Settings without that meaning it is active on the network.
Before assuming the problem is technical, confirm the status of your account through the channel where you contracted the plan (app, provider's website, or proof of purchase). If the line appears active and paid but the phone still has no service, then the next step is to check the installed profile.
Step 3: Reinstall or rescan the eSIM profile
An eSIM is not a physical card you can take out and put back in: it's a digital profile installed once using a QR code or activation data. If that profile was deleted—due to a factory reset, a phone change, or a failed update mid-process—restarting is not enough: you need to reinstall it.
For this, you need Wi-Fi (the eSIM cannot be downloaded using mobile data) and the original activation code. If you've already used that code once, it's normal for the system to reject it when you scan it again: many providers only allow activating a profile once per device, and to reinstall it on a different phone, you need to request a new code. If you've never done this process, it's advisable to first review the general guide for installing an eSIM before touching anything else in your phone settings.
Step 4: Check APN and mobile data settings
The APN (Access Point Name) is the configuration that tells the phone how to connect to the internet through that line. If it's empty, misspelled, or corresponds to another operator, the eSIM might show network signal but prevent you from browsing. This is an easy error to overlook because it doesn't prevent the line from "appearing" active in Settings.
Also, check that data roaming is activated if you are using the line outside your usual country, and that the eSIM is marked as the "main line for data" if your phone has more than one line configured. These types of configuration failures are among the most common eSIM problems after traveling or changing networks.
Step 5: Confirm your phone is eSIM compatible
Not all phones support eSIM, and some that do have it factory-locked if they come from an operator that only sells devices with a physical SIM. Generally, models with eSIM have been on the market for several years (iPhone since the XS, most recent Galaxy S and Pixel), but "unlocked for a single operator" versions sometimes disable the function via software even if the hardware supports it.
If you've reached this point and none of the previous steps worked, it's worth checking the list of eSIM-compatible phones before attempting anything else on the phone: if the device doesn't support eSIM or has it locked, no network setting will fix it.
How to activate eSIM on iPhone step by step
The process for installing or reinstalling an eSIM on an iPhone is the same regardless of the provider, including PilloFon: go to Settings, tap Mobile Data (or Cellular), select Add eSIM, and choose between scanning the QR activation code or entering the details manually if the provider gave them to you in text. The system downloads the profile, asks you to confirm which line to use for data and calls, and activates the line.
Two details that often cause confusion: you need Wi-Fi for the download (it won't work with data from another line if the phone only has one active data slot at a time), and the iPhone may take a few minutes to register the line on the network after installing the profile, even if it already appears as "active" in Settings. If after that time it still has no signal, go back to Step 1 of this guide and check airplane mode before reinstalling again.
If no steps worked: how to contact support
If you have already checked the five steps above and the eSIM still has no service, the problem is no longer dependent on the phone's configuration: it must be checked from the account or network side. Contact PilloFon's official support through the same channel where you contracted the line (app, website, or point of sale) and have your proof of purchase and the eSIM profile's ICCID handy, which is usually visible in Settings next to the line's name. These two pieces of information are what any operator requests first to check the status of a line from their system.
Keep in mind that most prepaid operators in the region do not offer phone support for activation issues: the usual channels are chat, email, or the app itself. If you have been waiting a long time for a response and your trip has already started, you probably need a temporary solution, and that's where the alternative in the next section comes in handy.
When the problem is with the provider, not you
There's a difference between an eSIM that fails once and one that fails every time you need it. If you've gone through the five steps, contacted support, and the problem recurs trip after trip—or they simply take days to respond while you're abroad without data—the cause is no longer your phone.
An eSIM doesn't "break": either the profile was uninstalled, the line expired, or the phone doesn't have data enabled for that profile. It's almost always one of these three things, and very rarely all three at once.
If your case no longer fits any of the three, the problem is with the operator's support or network, not configuration. For daily use in your country, that means insisting with your current provider. But if what you need is connectivity while traveling—and not a permanent line—the comparison changes: in that scenario, what matters most is not the price of the line but how quickly they respond if something goes wrong while you're away from home.
| Criterion | Continue with your current local line | International eSIM for travel |
|---|---|---|
| Primary use | Daily use line in your country | Only for when you travel |
| Support if something fails | Depends on operator's channels and hours | 24/7 in all languages via email and WhatsApp |
| Activation time | Variable, depending on profile reinstallation | Approximately 1 minute |
| Coverage | Limited to the country of origin | More than 200 destinations |
| Activation window | Depends on the contracted plan | 180 days from purchase |
That's the logic of a travel eSIM versus traditional roaming: it doesn't replace your local line, it solves the moment your local line fails you when you're away from home. If the provider that caused you problems was another—for example, Tigo—the same order of steps applies and you can check the guide to recover a Tigo eSIM. And if your phone doesn't have an active PilloFon eSIM today, below you can check the international eSIMs available for your next trip.
Frequently Asked Questions
How can I recover my Dua line on PilloFon?
The steps are the same as for any eSIM: restart the phone in airplane mode, confirm that the plan is still active and has a balance, and check that mobile data is assigned to that line. If the line is still active but the phone shows no service, it is likely that the profile has been deleted and needs to be reinstalled with a new activation code.
How to activate eSIM on iPhone PilloFon?
Go to Settings, tap Mobile Data, select Add eSIM, and scan the QR activation code (or enter the details manually if they were provided in text). You need a Wi-Fi connection for the download. The process is the same regardless of the provider.
How can I speak with a PilloFon advisor?
Use the same channel where you contracted the line: app, website, or point of sale. Have your proof of purchase and the eSIM profile's ICCID handy, visible in Settings next to the line's name, as this is usually the first thing they ask for to check a line's status.
Why does my eSIM suddenly say "no service"?
The most common causes are: airplane mode or data off for that line, an expired plan, a profile deleted due to a factory reset, or incorrectly configured APN settings. On phones with two lines, it could also be that mobile data is assigned to the other line.
Can I have two active eSIMs on the same phone at the same time?
Most phones allow installing multiple eSIM profiles, but only one can use mobile data at a time (except for some models with dual data connection). You can have a local eSIM and a travel eSIM installed simultaneously and choose which one uses data depending on where you are.
What should I do if I lost my eSIM activation QR code?
Contact the provider's support and ask them to resend the code or activation data associated with your purchase. Without that code, it is not possible to reinstall the profile if it has already been deleted from the phone.
Is the eSIM lost if I change phones?
Yes, in most cases. An eSIM cannot be physically "moved" like a traditional SIM: a new profile must be installed on the new phone, and some providers only allow activating the activation code once, so a new one may be needed.
How long does it take for an eSIM to work again after reactivation?
It depends on the provider and the network. As a reference, an international eSIM like PuraSIM's usually activates in approximately 1 minute once the profile is installed; other operators may take longer if activation depends on validating payment or account status first.
Conclusion and next step
If your PilloFon eSIM stopped working, in most cases it's resolved in the first two steps of this guide: restarting in airplane mode and confirming that the line is still active. If you've reached the step of reinstalling the profile or contacting support, it's no longer a configuration issue with your phone but something only the provider can check from their system.
And if the line that failed you was one you only needed for a trip, consider separating that use from your local line: an international eSIM designed for travel gives you coverage in more than 200 destinations, activates in approximately 1 minute, and you have 180 days from purchase to activate it when you need it, with 24/7 support in all languages via email and WhatsApp if something goes wrong while away from home. You can check the available international eSIMs or, if you want to better understand how they work before deciding, the definitive guide to traveling with eSIM in 2026 and the explanation of what an eSIM is and how it differs from a traditional line.
