Why the Holafly eSIM in Thailand saved us 🇹🇭
After hours of flying, the thought of looking for a phone shop in Bangkok is exhausting, hence the appeal of an eSIM Card in Thailand: why I chose the Holafly eSIM for my trip rather than a local chip.
The royal comfort of unlimited data everywhere
We loved not having to worry about our data quota anymore. Using Google Maps in the middle of Bangkok or posting our stories without counting, it’s truly the best. With unlimited data, we forgot the stress of gigabytes.
No more meticulous calculations of classic plans. We savored true freedom and total peace of mind. It seemed essential for this long trip.
This is the major advantage of this unlimited eSIM. We stay connected without any limits during the stay.
Keep your WhatsApp number without changing anything
No need to change accounts. Our WhatsApp application remained linked to our usual French number, which is essential for easily keeping in touch with everyone.
Our loved ones were able to reach us without any complex technical manipulation. Everything remained transparent, without any hassle. We absolutely did not regret this choice, believe us.
In short, it’s simple, we keep everything. We don’t change our habits. Here are the highlights:
- discussions maintained
- no ID change
- functional IP calls

QR code installation: a breeze before departure 📱
But before enjoying this freedom, you have to go through a surprisingly quick configuration step.
Express purchase and instant reception
We found ordering on the site really simple. You choose your destination, the duration, and voilà. For my Thailand SIM Card: why I chose the Holafly eSIM for my trip, it’s for this speed. Plus, with my Holafly promo code LAREUNION, you get an immediate 5% discount, which makes the offer even more attractive. Buy Holafly eSIM here.
Once the payment was validated, we didn’t wait. The email with the precious QR code arrived in a second. It’s instant after payment, a real joy.
Step-by-step configuration on iPhone and Android
For installation, go to your smartphone settings. Just click on “Add a plan” and scan the received code. It’s frankly intuitive and fast
Be careful, keep in mind that a stable Wi-Fi connection is essential. Without internet, it’s impossible to download your virtual SIM profile.
We share our complete review of the Holafly eSIM to help you prepare for your departure with peace of mind.
Immediate activation upon arrival
Upon landing in Bangkok or Phuket, we just activated the line in our settings. The data started immediately. It’s the joy of being able to order your ride-hailing service.
Above all, we avoided the endless queues at local counters. What a time saver! We were already in the taxi when others were still looking for their change.

5G connection and data sharing: the truth test 📶
Once we set foot on Thai soil, we forget the theory and finally move on to practice. This is exactly when my choice for the eSIM makes perfect sense. For my Thailand SIM Card, why I chose the Holafly eSIM for my trip becomes obvious: I have network immediately, without doing anything, without looking for a shop, and I can order my Grab, notify my loved ones, and check my itinerary as soon as I get off the plane.
Solid coverage from Bangkok to remote islands
The signal works everywhere, from Bangkok to isolated beaches. We often enjoyed ultra-fast 5G. It’s a real comfort for finding your way without ever lagging.
The Holafly network proved to be much more stable than the dubious hotel Wi-Fi. It’s much more secure for your bank accounts. The speed remains constant during your travels. We absolutely did not regret this choice.

Connection sharing and its small limits
However, be aware of the technical hotspot restriction. Sharing is limited to 1 GB per day depending on your plan. This is something to anticipate for your other devices.
To manage your consumption, turn off automatic updates. Carefully monitor the usage of your connected computers. This prevents draining your daily quota in just a few minutes.
In short, be vigilant with these very data-intensive uses of mobile data:
- High-definition video streaming.
- Extended HD video calls.
- Downloading large files.

Budget and compatibility: what to check before 💰
To avoid any unpleasant surprises, a few technical and financial checks are necessary before validating your cart.
Check if your smartphone is ready for eSIM
Your mobile must be completely unlocked. Recent iPhones or Samsung S series were perfect for our test. Double-check the origin of the device beforehand. A phone locked by an operator will not work at all, be careful.
Leave your usual physical SIM in the drawer. You will receive your bank security SMS without any fees. This is the full power of the dual SIM system that we really loved.
Here are the prices we noted to help you prepare your budget. Choose the duration that fits your vacation.
| Stay Duration | Data Volume | Indicative Price | Recommendation |
|---|---|---|---|
| 5 days | Unlimited | $19.50 | Short stopover |
| 7 days | Unlimited | $27.30 | One week |
| 10 days | Unlimited | $36.90 | Relaxing vacation |
| 15 days | Unlimited | $50.90 | Classic road trip |
| 30 days | Unlimited | $74.90 | Grand tour |
The duel with local airport SIM cards
Local offers were cheaper. But Holafly beat everyone on simplicity. We avoided the queues after ten hours of flying.

We saved a lot of time. The support spoke French and responded at any time. The peace of mind was well worth spending a few extra euros.
Ultimately, the value for money seemed perfectly correct to us. We pay a little more than a local SIM card, it’s true, but for the comfort, simplicity, and having internet as soon as we arrive, it’s well worth it. For our Thailand SIM Card, why I chose the Holafly eSIM for my trip was confirmed on site: no regrets, it’s clearly a choice we would make again. See Holafly eSIMs.
Thanks to unlimited data and the QR code activated in a flash, this alternative to the classic SIM card in Thailand offered us total peace of mind. Order yours before departure to avoid queues and stay connected as soon as you land. Finally enjoy your Thai adventure without the shadow of digital stress! 🇹🇭
FAQ
Can we keep our French WhatsApp number with the Holafly eSIM?
Absolutely! That’s one of the most practical aspects for staying in touch with loved ones. Since the eSIM is only for internet connection, your WhatsApp account remains linked to your usual number without any changes. We were able to continue sending photos and making video calls as if we were still at home. Just remember to keep your physical French SIM active in your phone to receive any bank verification or security SMS.
How much does the Holafly plan for 10 days in Thailand cost?
For a 10-day trip, the unlimited data plan is priced at $36.90 USD. We found it to be an excellent investment for total freedom. No need to monitor your gigabyte counter or desperately search for a Wi-Fi spot in the streets of Bangkok; you enjoy 100% of your trip without ever stressing about your consumption.
Is my smartphone compatible with this technology?
Most recent models work perfectly with eSIM! For Apple, it starts from iPhone XR and XS, and for Samsung fans, the Galaxy S range has been compatible since the S20. The only truly essential condition is that your phone must be unlocked for all operators. If your device is unlocked, you will have no problem installing your virtual plan.
Can I share my internet connection with other devices?
Yes, hotspot sharing is entirely possible, which was very helpful for connecting a laptop or a second phone. However, keep in mind that there is a small technical limit of 1 GB per day for data sharing. This is largely sufficient for checking maps or sending emails, but avoid streaming a series on multiple screens at the same time!
How is the eSIM installed before departure?
It’s a real breeze that takes just a few minutes. Right after purchasing online, you receive an email containing a precious QR code. You just need to scan it in your phone’s settings while you still have a stable Wi-Fi connection (this is the crucial step!). Once you land in Thailand, all you have to do is activate the line to get 5G instantly, without even going through a counter at the airport.
Is the connection really stable everywhere in Thailand?
We were genuinely impressed by the network quality! Thanks to partnerships with the best local operators, coverage is excellent, whether in the hustle and bustle of Bangkok or on more remote islands. We often had a much faster and more secure connection than the sometimes temperamental Wi-Fi in some hotels. It’s really the best for using your GPS or ordering a driver as soon as you get off the plane.
