eSIM not working is a common issue faced by both new and experienced users, especially those relying on digital SIMs for travel or remote connectivity. As the world shifts toward embedded SIM technology, many travelers and remote workers prefer the convenience of services like Holafly and others. But when your eSIM fails to activate, connect, or function properly, it can be frustrating—especially when you’re in a foreign country and need reliable data access. This article explores the most frequent causes and fixes for eSIM issues in a clear and neutral manner.
Understanding How eSIM Works
An eSIM (embedded SIM) is a small chip built into your device that replaces the need for a physical SIM card. Instead of inserting a card, you download a carrier profile (via QR code or activation code) and connect to the network digitally. Services like Holafly, Airalo, and others offer global eSIM data plans that are especially popular with international travelers.
However, because eSIM relies on software-based activation and carrier infrastructure, it’s more prone to technical or setup-related problems if not handled correctly.
Common Reasons Your eSIM Might Not Work
1. Your Device Isn’t Compatible or Unlocked
Not all phones support eSIM. Even if your model does, it may be carrier-locked.
- Fix: Check compatibility on your eSIM provider’s website
- Ensure your phone is unlocked for use with international or third-party eSIMs
2. eSIM Profile Not Installed Properly
A failed or incomplete profile installation can cause your eSIM to remain inactive.
- Fix: Reinstall the eSIM using the QR code or app
- Restart your phone and try scanning the QR again under good Wi-Fi
3. Network Not Detected
If your eSIM isn’t picking up a mobile signal, it may be due to poor local coverage or unsupported bands.
- Fix: Manually search for available networks
- Move to a location with better signal reception
4. APN Settings Are Missing
Some eSIM services require you to manually set the Access Point Name (APN).
- Fix: Check your provider’s instructions for APN configuration
- Go to mobile settings > eSIM profile > APN and input details
5. Data Plan Has Expired or Is Inactive
If your eSIM worked previously but suddenly stopped, your data plan may have expired.
- Fix: Log in to your provider’s dashboard to check validity
- Contact support if you think the plan was deactivated early
Holafly and Similar Services: What You Should Know
While Holafly is one of the most recognized eSIM providers globally, it functions like any other provider when it comes to the technical side. Their plans often include unlimited data, especially in regions like Europe, the US, and parts of Asia. But even Holafly users occasionally experience issues.
Some user-reported concerns include:
- Delays in QR code delivery
- Region-specific connectivity problems
- Difficulty switching between eSIMs mid-trip
However, their 24/7 customer support is generally responsive, and many issues are resolved quickly with live chat help.
Pro Tip: Activate Holafly or any eSIM before your trip while on stable Wi-Fi to avoid last-minute setup problems.
Troubleshooting Based on Device Type
For iPhone:
- Go to Settings > Cellular > Add eSIM
- Use camera to scan the QR code
- If it fails, select “Enter Details Manually”
For Android (Samsung, Pixel, etc.):
- Go to Settings > Network & Internet > SIMs
- Choose “Add Mobile Plan”
- Follow steps or scan QR manually
If nothing works, try resetting network settings:
- iOS: Settings > General > Reset > Reset Network Settings
- Android: Settings > System > Reset > Network Settings Reset
Avoiding eSIM Problems in the Future
Here are a few tips to help you avoid the “eSIM not working” nightmare:
- Always check compatibility before buying a plan
- Use stable Wi-Fi while activating
- Avoid deleting your eSIM unless told by support
- Keep your QR code saved in case you need to re-install
- Read reviews of the provider for your destination country
Final Thoughts
While eSIM not working can seem like a serious problem, most issues are minor and fixable within minutes. Whether you’re using a well-known provider like Holafly or any other, the process remains mostly the same: check compatibility, install the profile carefully, and follow troubleshooting steps if needed.
If things still don’t work, don’t panic—reach out to customer support with your order number and device info. In most cases, you’ll be online again in no time.
