While I always travel a lot, it feels like this month I have hit a record number of countries. I was in Indonesia, Thailand, Malaysia, Cambodia, Sri Lanka, and Vietnam! 

While I was deep in travel planning mode for flights, boat transfers, and visas, I also had to deal with an erupting volcano that messed up part of my trip, mentally prepare for a conference, and find storage in Bangkok for my dive gear. What I didn’t have to worry about was staying connected, because I had decided beforehand to get a Holafly Asia eSIM. That turned out to be an absolute game changer and took so much off my plate. 

What is a Holafly Asia eSIM and why is it so practical? Read on and I will tell you all about it. 

What is a Holafly Asia eSIM? 

Holafly is a leading eSIM provider. They offer eSIMs for over 200 destinations with daily unlimited data. Those destinations include most countries, as well as several regions. These regions are Africa, Europe, North America, and Central America, as well as the Balkans, the Caribbean, and Scandinavia, and a few more.

Some regions are purely geographical, as many visitors tend to travel to more than one country in a given region, and some are more topical – like North America was for World Cup visitors or different cruise routes.

Popular regions also include Asia and Southeast Asia, both of which Holafly offers as regional eSIMs. These eSIMs are a great choice whether you are a backpacker following the good old pancake trail, a foodie looking for some of the best plates on the continent, or a scuba diver in search of whale sharks and frogfish. Or a combination of all three, like myself. 

So what can a Holafly Asia eSIM actually do? Simply put, with a Holafly Asia eSIM, you will get data in a variety of countries. You don’t need to get different eSIMs for different countries, but just the one.

The advantages of using a Holafly eSIM Asia

So what are the advantages of getting a Holafly eSIM for Asia or Southeast Asia? There are a few:

Unlimited data & flexibility

Holafly makes it easy for you – you don’t have to think about how much data you will use or compare prices for various packages. All you have to do is determine how long you will be traveling and choose your eSIM accordingly. With a Holafly eSIM for Asia, you get maximum flexibility and can choose a validity of 1 to 90 days. 

You get unlimited data per day and thus never have to worry about running out of data or topping up. The math is mathing, and it couldn’t be easier!

1GB hotspot per day

I often use my eSIM to create a hotspot so I can stay connected on my laptop while traveling. If you’d like to do the same, the good news is that Holafly just upped their tethering capacity to 1GB per day. 

While you get unlimited data on your main device every day, you can share 1 GB with another. This can be your laptop or tablet, or someone else’s phone. 

No SIM card chaos

I have long been a fan of getting a local SIM card whenever I arrive at a destination, but lately I prefer an eSIM. Especially when you’re only staying a couple of days, comparing prices and data packages from local SIM suppliers is a chore. Network counters at the airport aren’t open 24/7, and you always need your passport to register your SIM card. And in some countries like Vietnam, scams with SIM cards are unfortunately very common, and you usually only notice after leaving the airport when it is too late.

The other day, I was sitting in an airport lounge before my flight and looked for the SIM card I brought from home. While I like to think I am very organized when it comes to my travel essentials, it took me a while to find it. I had an old SIM card from Thailand, one from Indonesia that stopped working after 2 days, and a few more. I didn’t know which one was which (have you tried reading the tiny writing on a SIM card?!) and had no idea which ones were even still valid. 

I decided then and there that I had enough of SIM card chaos. Now I keep my home SIM in my phone so I can receive banking SMS and such, and use a Holafly Asia eSIM instead of individual SIM cards from different countries. 

Always On

Holafly has recently added another bonus for their customers: Always On. It literally means you never have to be without data even after your Holafly Asia eSIM (or any other Holafly eSIM, for that matter) has expired. Keep your eSIM installed on your phone and you will get an additional 1GB of backup data per month. It is completely free and works in over 150 destinations. 

Perfect if you have to stay an extra night because a volcano erupted, or the airline adds an unforeseen layover in a country you didn’t plan on visiting. 

How much is an Asia eSIM from Holafly? 

One of the wonderful things about any Holafly eSIM is the easy pricing. You simply choose the destination you want to travel to and add the number of days you need an eSIM for. In the end, you get one price that includes unlimited data per day.

You can choose freely between an eSIM valid for any number of days up to 90 days. The best part: the longer the validity, the lower the price per day. Which basically means you save money if you travel longer (well, kind of). 

So much is the Holafly Asia eSIM? Prices start at $3.90 per day for both the Asia and the Southeast Asia eSIM. If you buy one for 15 days, it comes out to $50.50, which is only $ 3.37 per day. If you stay 30 days, it’s $2.46 per day, and it gets even less from there. 

Now, I was curious: was a Holafly Asia eSIM also cheaper than buying individual eSIMs? Besides saving time and effort organizing eSIMs for the countries you’re visiting, can you also save actual money? 

The answer depends on the destinations you plan to visit. Holafly eSIMs for countries like Thailand, Vietnam, Indonesia, Malaysia, and Japan are available for the same price as the Asia eSIM.It is $3.90 per day and you will get the same savings if you book longer. 

However, if you are planning to visit countries like Cambodia, Hong Kong, South Korea, Sri Lanka, and/or Laos, the situation is different. An individual eSIM for these countries is $5.90 per day and even $9.50 in Laos. Choose the Holafly Asia eSIM, and you will only pay $3.90 per day and thus save a whole lot – even if you are just staying for a short trip or a layover.

When does the Holafly eSIM Asia come in handy? 

I am always surprised by how few people seem to know about eSIMs when traveling and how many still rely on public wifi. It might speak to my attachment to the internet, but I don’t want to be without internet connection on the go. 

Here are a few examples from my recent trip when my Holafly Asia eSIM came in handy and made my life a little easier (and better).  

Travel interruption 

I happened to be in Lombok when Anak Krakatau erupted, causing major flight disruptions to and from Jakarta and other nearby airports. In fact, I was on my way from Gili Asahan to Lombok airport when I read the news. I had planned to fly to Jakarta, spend the night at the airport hotel, and fly to Berau early the next morning. 

None of this happened. Instead, I arrived at a chaotic Lombok airport with all flights in and out of Jakarta canceled. Luckily, I had already done my research in the car thanks to having an eSIM. I booked myself a hotel close to the airport, and found a different flight from Lombok to Berau for the next day. By the time I arrived at the hotel, they were turning away guests who hadn’t booked yet, and as I learned, most flight alternatives were sold out a couple of hours later too. 

Whaleshark encounter

If you see a whale shark and didn’t take a selfie, did it even happen? Well, I did both and couldn’t wait to send it to my dad. Having mobile data in the middle of the ocean off the coast of Borneo isn’t necessary but it is very practical. Especially to soothe worried parents’ minds that no, the whale shark is not dangerous and will not eat you. 

Unforeseen layover 

After Indonesia, I was supposed to fly direct from Jakarta to Bangkok. AirAsia had other plans and added a two-hour layover in Kuala Lumpur. My Holafly Asia eSIM was truly convenient because I had not planned this layover and wouldn’t have gotten a SIM card for Malaysia. And without internet, I probably wouldn’t have seen the notification about my flight’s gate change and run around KLIA like a headless chicken. And if you have ever been to KLIA, you know that airport is no fun for running around aimlessly. 

Bangkok arrival protocol

I usually book myself an airport transfer with Welcome Pickups when I arrive in Bangkok. The driver contacts me through WhatsApp so they know exactly when I leave immigration and have my luggage. While I could use airport wifi, it is honestly not the most reliable, so I used my eSIM. 

And once in the car, I used the Grab app to order my favorite sandwich from Bartels to my hotel in Bangkok. Honestly, I have done that so many times and there is nothing better than arriving at the same time as your favorite meal.

Sunrise at Angkor Wat

I’ve had the privilege of seeing the sunrise over Angkor Wat not once, not twice, but three times. Well, sort of. If you have been to Siem Reap, you will know what I mean – sunrise is not a given in the rainy season. Still, I was there, and I tried my best. 

During my last visit, I was there for a work conference and creator summit and was asked to post Instagram stories on the go. So yes, there I was at Angkor Wat – just me, my phone, my Holafly eSIM, and a few hundred tourists waiting for the sun to show her face.
