In short: when my eSIM isn't working, simply activating data roaming on its line, selecting it as the active data line, and restarting the phone almost always resolves the issue in less than a minute. A refund is only processed if the problem persists and support confirms the eSIM is defective.
An eSIM not working right after arriving at your destination is incredibly alarming, but in the vast majority of cases, it can be fixed in a couple of minutes without needing a refund. In this guide, you'll see why an eSIM fails and how to fix it step by step, when to contact support, and how to request a refund if it truly can't connect.
My eSIM is not working: first steps
If your eSIM isn't providing internet, before thinking about a refund, try this: restart your phone, check that data roaming is activated on the eSIM line, and that this eSIM is your active data line. These three steps resolve most issues in less than a minute.
The reason is simple: it's almost never a problem with the eSIM itself, but rather with phone settings or because the destination network hasn't activated yet. Many eSIMs "that don't work" are actually perfectly fine; it's just that the phone didn't have roaming turned on or was still using the home SIM for data. Before writing to support, it's worth understanding what data roaming is and how to activate it on your phone, because that's where most "no connection" alerts originate.
Why an eSIM fails (real causes)
When an eSIM doesn't connect, it's almost always due to one of these causes, listed from most to least frequent. Recognizing yours will save you time:
- Data roaming deactivated: one of the most common causes. The eSIM needs roaming enabled on its line to connect to the destination's operator.
- Wrong data line: the phone continues to use the Spanish SIM for data instead of the eSIM.
- Premature activation: you installed the eSIM but haven't arrived at the country yet or the plan starts counting later.
- Misconfigured APN: on some Android phones, you need to manually adjust the eSIM's APN; if you're reinstalling it, follow the step-by-step installation guide to ensure all settings are correct.
- Temporary lack of coverage: you are in an area with no signal (plane, basement, very isolated area).
Notice that none of these is "the eSIM is broken." That's why a refund is a last resort: it's almost always fixed by adjusting something on your phone. If you have doubts about the difference between eSIM and roaming, it's worth reviewing, as a good portion of "not working" alerts come from confusing these two concepts.
| Symptom | Most probable cause | Quick fix |
|---|---|---|
| No data upon arrival | Data roaming off | Activate roaming on the eSIM line |
| Uses home SIM | Incorrect data line selected | Set eSIM as data line |
| Slow or no data on Android | APN not configured | Adjust the eSIM's APN |
| No signal at a spot | Temporary coverage issue | Move or try manual network selection |
Myths about eSIMs that almost no one tells you
Before you keep fiddling with settings, it's worth debunking some ideas that waste time (and patience) when the problem doesn't actually exist.
- "The eSIM is an app and you have to open it": It's not. The eSIM is a profile that lives within the operating system, not an application that you open and close. If you're looking for an icon to "launch" it and it doesn't appear, that's not the problem: everything is managed from Settings, never from a dedicated app.
- "No service" means the local operator isn't working: Sometimes this message takes a couple of minutes to disappear even if roaming is already active, especially if you're coming from a rural area, the subway, or a long flight. The phone continues to search for the best nearby tower before settling, and forcing it with repeated reboots only prolongs the process.
- "With eSIM, I can't use VPN or I'll be detected differently": False. The eSIM works with any VPN exactly the same as a physical one. If you're traveling and concerned about connecting to public Wi-Fi in hotels or airports, the guide on VPN and travel privacy explains how to combine them without losing data speed.
- "A physical airport chip is more reliable than an eSIM": In practice, the opposite is usually true: queues, overpricing, and depending on whether the correct operator has stock. The comparison of international chip vs. eSIM debunks this with real traveler cases.
- "If I reinstall the eSIM, I lose the plan I bought": Not necessarily. On most phones, you can re-scan the same QR as long as you haven't completely deleted it from the device, though each manufacturer manages reinstallation differently, so it's wise to confirm with support before deleting anything as a precaution.
Quick fixes that almost always work
Here's the express checklist. Go through it in order, and as soon as one works, you'll have internet:
- Restart your phone. It sounds clichéd, but it forces the phone to re-establish the local network and fixes half the cases.
- Activate data roaming in Settings, on the eSIM line (not your home line).
- Select the eSIM as the data line so it uses its plan and not your Spanish operator's.
- Try manual network selection: In Network Settings, deactivate "automatic" and choose a local operator from the list.
- Toggle airplane mode on and off for 10 seconds to make it search for a network again.
Key tip: install the eSIM with Wi-Fi before traveling, but don't expect to have internet until you land at your destination. No data at home is normal, not a fault.
If you're still without a connection after following this entire list, and you've already confirmed that your phone is eSIM compatible and unlocked, then it's time to contact support, although this happens in very few real cases.
When to contact support
Write to support when you've followed the list above and the problem persists: the eSIM doesn't appear after installation, the QR gives a repeated error, or you've been at your destination for hours without getting data despite having roaming activated. Good support will respond quickly and in your language.
At PuraSim, you have 24/7 support in all languages via email and WhatsApp, so no matter what time it is at your destination, someone can help you reactivate the eSIM, resend the QR, or check the plan status, whether it's for an eSIM for Spain or any of the more than 200 available destinations. Have your order number and a screenshot of the error handy; with that, resolving the case is much faster. If the issue is that the email with the QR didn't arrive, first check your spam folder and the address you used for purchase: this is a common cause when the QR "doesn't appear," and it can be resolved by having support resend it in a couple of minutes.
How to request a refund for your eSIM
If support confirms that the eSIM is defective and there's no way for it to connect, you are entitled to a refund. The process, in general, is as simple as this:
- Contact support explaining the problem and the steps you've already tried.
- Provide your order number and screenshots of the error if you have them.
- Await verification: they will verify that the eSIM has not been used or that there is a real network failure.
- Receive the refund to your original payment method once approved.
The key is that a refund is processed when the fault lies with the product, not when the eSIM was functional but the problem was due to phone configuration or compatibility. That's why it's advisable to save the email with the QR and not delete the eSIM until the case is closed.
How long does it take? There is no fixed timeframe that can be promised because it depends on when you confirm the data requested by support, but the process itself is short once everything is verified: the refund goes to the same payment method you used for purchase, so check your card summary or payment platform in the following days, not your PuraSim account. If you purchased thinking of several countries on the same trip, indicate this in your message to support: it helps to check if the plan was activated in any of the countries before resolving the case.
How to avoid problems next time
Most scares with eSIMs can be avoided with a little preparation before you leave. Get these things ready and your next trip will start connected without drama:
- Buy from a brand with real support: one where you can write and get a response in Spanish at any time.
- Install the eSIM at home with Wi-Fi a few days beforehand, to detect any problems with time to spare.
- Check your phone's compatibility before paying.
- Don't delete it until the trip is over: if you accidentally delete it, recovery is slower.
- Note down the name of the local operator that appears in Settings when you install it: if you need to do a manual network selection at any point during your trip, knowing which operator to look for saves you minutes of trial and error.
- Monitor your data consumption if your plan has limited data: running out of data is easily confused with "the eSIM isn't working," when in reality the plan has been exhausted. The guide on tips for saving data while traveling includes specific settings (disabling automatic updates, limiting 4G streaming) that extend your plan for several days without you noticing the difference.
With this routine, the chances of something going wrong are minimal, and if it does, you'll resolve it in minutes. The peace of mind of staying connected while traveling is well worth those five minutes of preparation.
An honest warning: if you're only going for a short weekend in a country with good coverage from your own plan (for example, a quick hop within the European Union with a Spanish plan that already includes European roaming), it might not be worth buying anything new. eSIM makes sense when your operator's roaming costs skyrocket, when you're visiting several countries consecutively, or when you need more data than your plan covers; don't buy it just because.
Frequently asked questions
Why isn't my eSIM working right after I arrive at my destination?
The most common reason is that data roaming is deactivated on its line or that your phone is still using your home SIM for data. Restart your phone, activate roaming on the eSIM, and select it as your data line: this solves most cases.
Will I get a refund if the eSIM doesn't work?
Yes, if support confirms there's a real product fault and not a configuration issue. If the eSIM was functional and the problem was with the phone (incompatibility, roaming off, wrong data line selected), a refund is usually not applicable because the service was provided correctly.
Can I request a refund for an already used eSIM?
It depends. If you have consumed data, it is understood that the eSIM was working, so a full refund usually does not apply. If it has not been activated or used and there is a demonstrable problem, then yes. Contact support with your order number so they can evaluate your specific case.
How long does it take for support to respond?
With 24/7 support via email and WhatsApp like PuraSim's, responses usually come quickly at any time, which is key when you have a significant time difference with Spain. Have your order number and screenshots of the error ready to speed up the solution or, if necessary, the refund.
What if the problem is that my phone isn't compatible?
If your phone doesn't support eSIM or is carrier-locked, the eSIM won't be able to work even if it's correct. That's why it's important to check compatibility before buying. In that case, since the product is fine, support usually assesses the refund based on discretion.
How do I know if the eSIM installed correctly even if I don't have coverage yet?
Go to Mobile Data Settings: if you see a second line with the destination operator's name (not your Spanish one), the installation was correct even if it doesn't show a signal until you land. Not getting data at home, with Wi-Fi, is normal and doesn't mean it's broken.
I scanned the QR but the eSIM doesn't appear on my phone, what do I do?
First, check that your phone had an internet connection (Wi-Fi or data) during the scan, because without it, the installation will partially fail. If no new line appears, do not re-scan the same QR on your own: most operators invalidate it after the first attempt, so write to support for them to reactivate it or generate a new one for you.
Conclusion
An eSIM not working is almost never the eSIM's fault: restarting, activating roaming, and selecting the correct data line resolves most cases in a minute. And if there truly is a fault, good support and a clear refund policy have you covered. Travel with a PuraSim eSIM, with 24/7 support in all languages via email and WhatsApp to ensure no unexpected issue leaves you without connection.
