TL;DR:
So you’ve landed in a new country, you’re standing at the arrivals gate, and your Holafly eSIM just… won’t connect. No signal bars, no data, nothing. We’ve all been there and it’s incredibly frustrating, especially when you need maps, a ride, or to let someone know you’ve arrived.
The good news? Most Holafly eSIM problems are surprisingly easy to fix. In about 90% of cases, it’s a simple settings issue on your phone — not a problem with the eSIM itself. Let me walk you through every fix I know, plus some solid alternatives if you decide Holafly isn’t the right fit for your next trip.
Why Is Your Holafly eSIM Not Working?
Before jumping into the fixes, it helps to understand what’s actually going wrong. When a Holafly eSIM fails to connect, the issue usually falls into one of these buckets:
| Common Cause | What It Means | Difficulty to Fix |
|---|---|---|
| Device not eSIM-compatible | Older phones or certain regional models don’t support eSIM technology | Can’t Fix |
| Phone is carrier-locked | Your phone is tied to a specific carrier and won’t accept third-party eSIMs | Medium |
| Data roaming disabled | Your phone’s roaming setting is off, blocking international network access | Easy |
| Incorrect APN settings | The Access Point Name wasn’t configured correctly during setup | Easy |
| Network selection failure | Your phone can’t auto-detect a compatible local carrier | Easy |
| Weak Wi-Fi during install | Wi-Fi dropped mid-installation, causing an incomplete eSIM profile download | Moderate |
| Too many eSIM profiles | Your device hit the max number of stored eSIM profiles | Easy |
| Expired or inactive plan | Your Holafly plan hasn’t been activated yet or has already expired | Easy |
| Software outdated | Your phone’s OS is behind on updates and doesn’t support the current eSIM standard | Moderate |
9 Proven Fixes: How to Get Your Holafly eSIM Working
Try these fixes in order. Most people get connected within the first 3–4 steps. If you’ve already tried the obvious stuff, skip ahead to the later fixes.
Check Device Compatibility & Unlock Status
This one catches more people than you’d think. Not every phone supports eSIM, and even if it does, a carrier-locked device will block any third-party eSIM from working.
Android: Settings → Connections → Mobile Networks → Network Operators. If you can add new SIMs, you’re good.
eSIM-compatible iPhones: XS/XR and newer. Android: Samsung Galaxy S20+, Google Pixel 3+, and most flagships from 2020 onward.
Restart Your Phone
Sounds basic, right? But restarting forces your device to re-register the new eSIM profile on the local network. Skip this step and nothing else might work.
Android: Hold Power button → Tap Restart
Enable Data Roaming
This is the #1 reason Holafly eSIMs don’t work abroad. Data roaming must be turned on for the eSIM to connect to local networks in another country. Without it, your phone actively blocks the connection.
Android: Settings → Network & Internet → [Holafly eSIM] → Data Roaming → Turn ON
Toggle Airplane Mode On/Off
Toggling Airplane Mode forces your phone to drop all active network connections and re-establish them from scratch. This clears temporary registration issues that stop the eSIM from connecting.
Turn on Airplane Mode → Wait 5–10 seconds → Turn it off → Wait up to 1 minute for the device to re-register on the network. Simple but effective.
Set APN to “Global” Manually
An incorrect APN (Access Point Name) blocks data even if you see signal bars on your phone. Holafly uses “Global” as its APN. If your phone didn’t auto-configure it, you’ll need to set it yourself.
Select Network Manually
Sometimes your phone just won’t auto-detect a compatible local carrier. Manually picking one from the list usually fixes this.
Remove Old eSIM Profiles
Having too many disused eSIM profiles on your phone can cause network conflicts. Clean house by removing any old ones you no longer need.
Update Your Phone Software
Outdated operating system versions sometimes don’t support the current eSIM standard. A quick update can resolve compatibility issues you didn’t even know existed.
Reset Network Settings (Last Resort)
This is the nuclear option — it clears ALL saved Wi-Fi passwords, Bluetooth pairings, VPN profiles, and mobile data configurations. Only use this if nothing else has worked.
Android: Settings → General Management → Reset → Reset Network Settings.
Back up your Wi-Fi passwords before doing this. You’ll need to re-enter them all after the reset.
Always install your Holafly eSIM while you still have stable Wi-Fi — ideally at home or your hotel before heading to the airport. A weak or dropping connection during installation is one of the most common causes of eSIM activation failures.

Accidentally Deleted Your Holafly eSIM?
It happens more often than you’d think. If you accidentally removed the eSIM profile from your phone, here’s what to do:
If you still have access to the device where the eSIM was installed, try reinstalling it using the same QR code or manual codes (SM-DP+ address and activation code) from your original purchase email. If you’ve lost your phone or it’s unusable, contact Holafly support with your order details and ask for a new QR code or activation link. They can usually reissue the eSIM if your plan is still active.
Holafly offers up to 6 months to request a refund on unused eSIMs. If the eSIM has been activated but didn’t work due to network infrastructure issues, they can offer a full refund. There’s a $3.50 USD administrative fee on partial refunds. Always report issues during your trip, not after — they can’t guarantee refunds if you wait.

Which Travel eSIM Should You Actually Choose?
Here’s my honest take based on real-world pricing and performance:
Stick with Holafly if you’re a heavy data user who streams constantly, uses video calls daily, or just doesn’t want to think about data limits. The unlimited plans are genuinely unlimited, and the 24/7 WhatsApp support is a nice touch when you’re in a different timezone. At around $6/day, it’s actually cheaper than carrier day passes for longer trips.
Go with T-Mobile if you’re already a customer — it’s a no-brainer. Their Go5G Plus and Experience More plans include up to 5–15GB of high-speed international data in 215+ countries at no extra cost. You keep your number, your texts are free, and you don’t need to install anything extra. For longer trips, their $50 International Pass gives you 15GB over 30 days. Hands down the best carrier deal for travelers.
Pick Verizon if you want simplicity and reliability. Their $12/day TravelPass gives you unlimited talk, text, and 2GB of high-speed data per day in 210+ countries — and you only pay on days you actually use your phone. For trips longer than 9 days, their $100/month International Monthly Plan (20GB + unlimited slower data) is the smarter option.
Choose AT&T if you’re taking a short trip under 10 days. Their International Day Pass costs $12/day but caps at $120 total — meaning trips longer than 10 days don’t cost extra. It’s an underrated feature that makes AT&T surprisingly affordable for 2–4 week vacations. Prepaid customers can also grab a $35 weekly travel add-on with 5GB of data.

5 Tips to Avoid eSIM Problems on Your Next Trip
Prevention is always better than troubleshooting at 2 AM in a foreign airport. Here’s how to make sure your eSIM works perfectly every time:
1. Install before you leave home. Always set up your eSIM while connected to reliable Wi-Fi. Don’t wait until you’re at the airport or in the taxi — a dropped connection during installation is the #1 cause of activation failures.
2. Check compatibility first. Before buying any eSIM, verify your phone model supports eSIM technology AND that it’s carrier-unlocked. This takes 30 seconds in your settings and saves hours of frustration later.
3. Screenshot your QR code and manual codes. Keep your activation QR code and SM-DP+ address saved somewhere accessible offline. If you need to reinstall, you’ll have everything ready without needing internet access.
4. Remove old eSIM profiles. Clean up any eSIMs from previous trips before installing a new one. Old profiles can cause conflicts and prevent new ones from connecting properly.
5. Keep your OS updated. Phone manufacturers regularly update eSIM support in their software. Running the latest version of iOS or Android ensures the best compatibility with any eSIM provider.
The most common reason is data roaming being turned off. Go to Settings → Mobile Service → select your Holafly eSIM → and toggle Data Roaming ON. Then restart your phone. If that doesn’t work, try toggling Airplane Mode on for 10 seconds, then off. Your phone needs to re-register on the local network after arrival, and these two steps handle that in most cases.
Yes. Holafly offers up to 6 months to request a refund on unused eSIMs. If the eSIM was activated but didn’t work due to network issues on their end, they can issue a full refund. Partial refunds (minus a $3.50 administrative fee) are available in other cases depending on data used. Contact their support via email at help@holafly.com or WhatsApp at +1 (661) 384-8482 during your trip — they can’t guarantee refunds if you wait until after.
It depends on the trip length. For a 14-day trip, Holafly costs roughly $56–84 for unlimited data, while Verizon’s TravelPass would run you $168, and AT&T’s Day Pass caps at $120 after 10 days. T-Mobile customers on Go5G Plus or higher plans get 5–15GB of international data included free, making T-Mobile the cheapest option if you’re already a customer. For heavy data users on longer trips, Holafly often works out cheaper — but for short trips where you already have a carrier plan, the carrier eSIM is more convenient.
The Holafly APN is simply “Global”. Most phones auto-configure this when the eSIM is installed, but if yours didn’t, go to Settings → Mobile Service → Mobile Data Network (iPhone) or Settings → Connections → Mobile Networks → Access Point Names (Android) and enter “Global” as the APN. Save and restart your phone for the change to take effect.
No — only iPhones from the XS/XR (2018) onwards support eSIM technology. This includes iPhone XS, XR, 11, 12, 13, 14, 15, and 16 series. Your iPhone also needs to be carrier-unlocked. You can check by going to Settings → General → About → Carrier Lock. If it says “No SIM restrictions,” you’re good to go. If it says “SIM locked,” contact your carrier to unlock it first.
Yes, but with limits. Holafly’s Unlimited plan includes hotspot functionality with a cap of about 10GB per day for tethering. That’s plenty for checking emails and light browsing on your laptop, but may not be enough for downloading large files or streaming on a second device all day. If tethering is critical for your trip, all three major carriers (T-Mobile, Verizon, AT&T) include hotspot with their international travel plans — though data limits vary by your specific plan tier.
T-Mobile wins hands down for international travelers. Their Go5G Plus and Experience More plans include 5GB of high-speed data in 215+ countries — for free, with no add-on needed. After that 5GB, you still get unlimited data at 256kbps (usable for maps and messaging). Plus, texting is free abroad and calls are just $0.25/minute. If you need more, their $50 International Pass gives you 15GB over 30 days with unlimited calling. Verizon and AT&T both charge $12/day, which adds up fast on longer trips.
Holafly offers 24/7 support through multiple channels. The fastest way is via WhatsApp at +1 (661) 384-8482. You can also reach them through live chat on their website and app, via email at help@holafly.com, or through their Instagram and Facebook pages. WhatsApp typically gets the fastest response — most travelers report getting answers within minutes rather than hours.
It depends on the situation. If you still have access to your old phone, remove the Holafly eSIM from it (delete the eSIM profile in settings), restart the old phone, then install the eSIM on your new device using the same QR code or manual codes from your purchase email. If your old phone is lost, stolen, or unusable, you’ll need to contact Holafly support with your order details and request a reissue. They can confirm if the plan is still active and advise whether they can provide new activation codes for the replacement device.
