Quick summary: Best eSIM for Korea
We used a whole host of eSIMs for travel in Korea to find out which is best. In short, our top pick is Ubigi by a country mile. Ubigi scored ridiculously high in our speed tests and offered very strong signal throughout. Nomad was our second favorite option. Whilst slower than Ubigi, speeds were still very fast and signal was strong. Firsty rounds off the list, offering unique data plans with up to 2GB of data per day for 2.50 EUR (about $2.72), fast speeds and solid signal. One for the power users.

The best of the rest
aloSIM – Narrowly missing out on the top 3, AloSIM offers 2 networks to choose from, so signal is rarely a problem. Prices are reasonable and new plans get a free phone number with a limited amount of internet calls or SMS.
GigSky – Below average speeds and quite overpriced versus competition.
Holafly – High data but very underwhelming speeds and more expensive than other high data options like Firsty.
Saily – Great pricing, but unfortunate delays in setup meant we weren’t able to test.
Airalo – Only 2 plans available in Korea, both unlimited and work out more expensive than Firsty. However, Airalo gives you 3 GB of data per day before slowing down, Firsty gives 2 GB. You also need to verify your identity by taking a picture of your ID and a selfie. Not ideal.
MobiMatter – Many additional packages available.
Best eSIM for South Korea: An introduction
What can we say about South Korea? We went to Korea completely unsure of what to expect but even then, it surpassed all of our expectations.
Known as the “Land of the Morning Calm,” Korea is a special destination that combines one of a kind landscapes with modern flair in the cities. From the peaks of Seoraksan national park to the coast of Busan, Korea’s natural beauty is amazing. We particularly enjoyed watching the sunrise from the North Seoul Tower early in the morning. What a view.
Nomad eSIM app next to N Seoul Tower at sunrise
The food scene is incredible too, from Korean barbecue and bibimbap to street food at one of their many markets – even if the weather was just a little bit hot for tteokbokki!
Most of all, the Korean people are warm and welcoming, making you feel right at home. We can’t count the amount of positive interactions we had with the people, even if we know next to no Korean.
Korea offers a perfect mix of tradition and modernity, natural beauty and city life. It’s a place that’s stayed with us long after we left.
Hot Tips
Korea can be a little bit challenging as a tourist, without speaking any Korean or sometimes, without a Korean phone number – and none of the eSIMS we’ve seen do come with one. Not to worry however, we recommend the following:
Taxis: Kakao T was absolutely hassle free for us.
Maps: Kakao Map was our first choice, Naver Map is another option. Google Maps will not give you driving or walking directions in Korea so you’ll have to use a local option. Kakao Map worked best for us, though both were a little bit slow to load.
Food Delivery: We weren’t able to sign up to any of the food delivery services without a local number during our time in Korea. However we have since seen talk of Baedal Minjok working with foreign numbers. This is available on the App Store and Play Store but will have a Korean title when you search for it.
All apps featured are available internationally, you won’t need to set your region to Korea to download.
Travel ESIM Expert on location
Considerations for choosing an eSIM in Korea:
- Data required: You’ll need to know roughly how much data you require to get the best value for your money. Make sure you consider your overseas data usage habits, length of stay etc. Plan options range from 1GB of data all the way through to unlimited data.
- Trip and plan duration: Consider how long you will be overseas and purchase a plan that can last for the entire trip. Ensure that you install your eSIM prior to your trip and activate it eSIM either just before leaving if possible or upon arrival in your destination so you don’t waste plan validity time.
- Countries to visit: Heading to one country? Simply purchase your eSIM to cover Korea. Visiting more than one country? You have the option to buy multi country plans that will cover the entire region. At TEE, we tend not to recommend them as they are usually more expensive than single country plans. You get more value by simply purchasing a different eSIM for every country and using your data fully.
- Do you need a phone number? As mentioned, a phone number is quite useful in Korea, but you can certainly get by without one in Korea and around the world. If you do, a physical SIM may be the better option for you.
- Tethering/Personal Hotspot functionality? Do you need an eSIM that you can connect other devices to? Make sure that you get an eSIM that supports personal hotspot/tethering.
- eSIM Performance: Make sure you get the eSIM that performs best overall in a number of factors including signal, speed, price/value, app, loyalty schemes, customer support, app performance, etc. Our top 3 most important factors? Speed, signal and price/value. Which are the best eSIM for South Korea? Read on and we will reveal all…
Best eSIM for South Korea: A breakdown
#1
1. Ubigi
The best speeds we’ve seen in an eSIM so far, strong signal and great value. Get it in Korea. See Ubigi review.

Pros

Cons
- No loyalty program
- Slow customer support
What you need to know
Ubigi is the best eSIM for travel in South Korea by far. Speeds are faster than our home connection, signal is strong throughout and 3 GB of data for $9 is the perfect option all round. Just hope things don’t go wrong as Ubigi customer support is not great.
Signal
Like a lot of travel eSIMs in Korea, Ubigi partners up with SK Telecom to provide its signal. In truth, we found signal to be solid and reliable across all networks, in pretty much all places that we visited and in between. Reception in the main city of Seoul was bulletproof and we rarely found ourselves without 5G and 2 or more out of 4 bars of signal. This was the case in Busan too, we were never found without strong signal, even on the way there.
The plan is data only, you won’t get any SMS or calls included. Ubigi only works on SK Telecom, you won’t have the ability to switch to any other networks but in our experience, you probably wouldn’t need to.
Speed
Allow us to get excited about this one. Firstly, let’s cover what it’s like in general usage. In short, it’s fast and seamless, no matter what you’re trying to do. We were able to stream, watch video in the highest of definition, video call, browse sites and social media very easily. We felt like we were on our home connection, but Ubigi is actually faster than that.
Let’s talk speed tests. If you haven’t seen any of our other country guides, we select the main eSIMs for travel and test them for speed in every country we go to. In Korea, Ubigi’s download speed was 351 Mbps. That is:
- The fastest download speed in Korea.
- The fastest download speed of any travel eSIM provider in any country that we’ve tried so far.
- Faster than our home internet connection, which is around 250 Mbps.
So hopefully you get the idea, in Korea, Ubigi is lightning fast.
We never recommend uploading much on an eSIM but we do feel the need to caveat that the upload speed is only 7.5 Mbps, quite slow but still third fastest in Korea amongst eSIMs tested.
Speed comparison:
| Provider | Ubigi | Nomad | Firsty | AloSIM | GigSky | Holafly |
| Download Speed (Mbps) | 351 | 149 | 94.5 | 93 | 40 | 6.96 |
| Upload Speed (Mbps) | 7 | 3 | 10 | 9 | 0.1 | 3 |
| 4G or 5G? | 5G | 5G | 4G | 5G | 4G | 5G |
| Fastest Network | SKT | SKT | “Firsty” | KT | “GigSky” | “Holafly” |
Price, value and offers
Ubigi pricing breakdown is as follows:
| Data | Price | Validity | Price per GB |
| 1 GB | $6.00 | 7 Days | $6.00 |
| 3 GB | $9.00 | 30 Days | $3.00 |
| 10 GB | $26.00 | 30 Days | $2.60 |
| 25 GB | $72.00 | 30 Days | $2.88 |
Ubigi is in the mix for the cheapest and best value packages in Korea, if you pick the right one. We think for regular users, the 3GB for $9 is a solid choice, with Ubigi’s 3 GB package only bettered in pricing by Saily amongst our picks. However, for more data, you might be better served going for other options. Ubigi’s high data option of 25 GB comes in at $2.88 per GB and $72. Nomad and Saily offer 20 GB packages at $1.50 and $1.45 per GB respectively. Nomad would likely be better value there.
Generally Ubigi’s price per GB decreases the more data you purchase, but their 25 GB package actually costs more per GB ($2.88) than their 10 GB package for $2.60 per GB. If you do want Ubigi’s fast speeds and a lot of data, we’d recommend purchasing in 10 GB blocks.
Best of all? Travel ESIM Expert users get 10% off new purchases with coupon: TEE10.
App
Ubigi’s app is functional but could really do with some development. Details are a bit lacking; you won’t know what network you can use and whether it’s 4G or 5G for example. The main thing that annoys us is that it’ll log you out frequently for no apparent reason. Get used to that login screen!
Anything else?
Ubigi still doesn’t have a loyalty scheme, a real shame as we’d have saved some serious money by now!
#2
2. Nomad
Fast speeds, solid signal and great value at high data packages. See Nomad review.

What you need to know
As always, Nomad is a very solid option. Speeds are the second fastest among eSIM providers tested and signal is strong. A very polished experience.
Signal
Nomad works on SK Telecom in Korea and works on 5G as well. We have to say we were impressed with signal on SK Telecom across the various eSIMs throughout the country. We didn’t have any issues with signal on Nomad either, performance was strong. Unfortunately you won’t be able to change networks if necessary and all plans are data only, no SMS or calls available here.
Speed
Nomad eSIM was fast in Korea. We were able to do just about everything we wanted right from our phones. We threw all sorts of things its way such as social, video calls etc and it rarely struggled. Streaming video wasn’t quite as solid as Ubigi, so we weren’t able to reach the very top definition on Youtube videos without a little bit of a loading delay.
So what did our tests say? They backed up our experience. Download speeds were 149 Mbps, a fast speed that’s up there amongst some of the top speeds we’ve experienced.
Speed comparison:
| Provider | Ubigi | Nomad | Firsty | AloSIM | GigSky | Holafly |
| Download Speed (Mbps) | 351 | 149 | 94.5 | 93 | 40 | 6.96 |
| Upload Speed (Mbps) | 7 | 3 | 10 | 9 | 0.1 | 3 |
| 4G or 5G? | 5G | 5G | 4G | 5G | 4G | 5G |
| Fastest Network | SKT | SKT | “Firsty” | KT | “GigSky” | “Holafly” |
Price, value and offers
Nomad pricing breakdown is as follows:
| Data | Price | Validity | Price per GB |
| 1 GB | $5.00 | 7 Days | $5.00 |
| 3 GB | $11.00 | 30 Days | $3.67 |
| 5 GB | $14.00 | 30 Days | $2.80 |
| 10 GB | $20.00 | 30 Days | $2.00 |
| 15 GB | $24.00 | 30 Days | $1.60 |
| 20 GB | $30.00 | 45 Days | $1.50 |
Pricing wise, Nomad is an interesting one in South Korea. Price per GB for their 1GB and 3GB plans is not the best. Where Nomad really becomes better value is for packages of 5 GB or more. Their 20 GB for $30 plan is only $1.50 per GB, which is great value, beaten only by Saily’s price of $29.99.
We feel with these low prices combined with their fast speeds, Nomad is the choice to go with for higher data.
App
Nomad’s one of the better apps that we use, generally everything works smoothly, there’s minimal waiting around and best of all, loads of details around networks, 5G/4G etc for geeks like us. Visually it’s modern and fun too. If you’re one of those people that leaves your phone in dark mode, the dark colors of this app are perfect for you as well.
Anything else?
Nomad offers a loyalty scheme and discounts as well. Make sure you check out our offers to ensure you get the best price!

3. Firsty
Our first time using Firsty and it was a very solid experience. We could get used to these high data plans.

What you need to know
This is the first time that we’ve managed to properly test Firsty and we really have to say that we were impressed. Firsty works a bit differently to most other eSIMs we’ve used, allow us to explain…
With Firsty, you have two options:
- “Firsty Free” is their free service that allows you very limited speed internet access in return for watching ads, about enough to send WhatsApp messages.
- “Firsty Fast” is a pay per day service that offers 2 GB of data per day at full speed. That’s a lot of data.
Sometimes high data travel eSIM providers can highly throttle (reduce speed) their plans, but not here. Signal was very solid too.
Firsty is a very interesting proposition, especially for digital nomads requiring high data.
Signal
Firsty had strong signal throughout Korea, we had no complaints with it and generally saw the same amount of bars of signal as our second active SIM at all times. For us, the plan was “only” 4G but outperformed a number of others that did connect to 5G.
Firsty is one of those eSIMs for travel that renames every available network, so we were simply joined to “Firsty” the whole time. You can’t switch to any other network.
Speed
As we touched upon, it’s claimed that sometimes eSIMs offering “unlimited” or high data plans throttle the speed down to a snail’s pace, what’s the good in that? Though we generally used about 1.5 GB of our 2 GB allowance daily, speeds did not decrease – that is great news!
Speeds were decent, if not the fastest we tested. We were able to do all of our usual browsing, calling, streaming etc, which is a major positive. In terms of speed test scores, Firsty was third(y) out of all eSIMs tested, narrowly beating out AloSIM with a score of 94.5 Mbps, versus AloSIM’s 93 Mbps. All in all Firsty was a very solid option in Korea.
Speed comparison:
| Provider | Ubigi | Nomad | Firsty | AloSIM | GigSky | Holafly |
| Download Speed (Mbps) | 351 | 149 | 94.5 | 93 | 40 | 6.96 |
| Upload Speed (Mbps) | 7 | 3 | 10 | 9 | 0.1 | 3 |
| 4G or 5G? | 5G | 5G | 4G | 5G | 4G | 5G |
| Fastest Network | SKT | SKT | “Firsty” | KT | “GigSky” | “Holafly” |
Price, value and offers
With Firsty, the more days of validity purchased, the less the price per day will be.
Firsty pricing breakdown is as follows. Note that prices are quoted in EUR, so we have converted to USD at May 2024 exchange rates.
| Data | Price per day | Validity |
| 2 GB per day | $2.71 (Approx) | 1-10 Days |
| 2 GB per day | $2.38 (Approx) | 11-20 Days |
| 2 GB per day | $2.27 (Approx) | 21-25 Days |
| 2 GB per day | $2.11 (Approx) | 26-30 Days |
As we covered, Firsty is very different to most of the other travel eSIMs on the list and pricing is a big part of that. We think that these prices and plans are ideal for power users needing a lot of data as well as short-term users who can make use of a 1 day plan for around $2.71 if required.
It’s best to compare with a brand like Holafly who offer similar in Korea and many other countries. Holafly’s Korea pricing is:
| Data | Price | Validity |
| Unlimited | $21.00 | 5 Days |
| Unlimited | $29.00 | 7 Days |
| Unlimited | $37.00 | 10 Days |
| Unlimited | $51.00 | 15 Days |
| Unlimited | $62.00 | 20 Days |
Head to head:
| Days | Firsty | Holafly |
| 5 Days | $13.53 (Approx) | $21.00 |
| 7 Days | $18.94 (Approx) | $29.00 |
| 10 Days | $27.06 (Approx) | $37.00 |
| 15 Days | $35.72 (Approx) | $51.00 |
| 20 Days | $47.62 (Approx) | $62.00 |
Firsty is evidently cheaper but is very transparent that your data limit is 2 GB per day, after which you’ll need to switch to their free plan. Holafly claims unlimited data but the word online is that speeds are throttled (slowed) after using a certain amount of data.
We can also help get that price down even further with our exclusive coupon code. Use code TRAVELESIMEXPERT to take 15% OFF your next purchase.
All in all, we think Firsty offers great value for users requiring a lot of data in Korea.
App
Firsty’s app is functional, bright and to our eye, looks pretty cool. We think it does need a little more information available around data usage. We’d like to see data usage front and center next to validity time left for example. It’d also be useful to get detailed information around networks available prior to purchase.
Anything else?
One very cool feature is that plans can transfer from country to country. For example, we had bought a 4 day plan in the USA prior to departing for Korea on day 2 of the plan. As Firsty supports USA and South Korea, our data simply switched over to Korea and we were able to continue using it for the remaining days from the moment we touched down.
Firsty doesn’t have a loyalty scheme at the moment and though it has live chat support, responses are quite slow.

What you need to know
AloSIM is a very solid choice for Korea. With fast speeds, reasonable pricing and a choice between 2 networks for the best signal possible, you can’t go far wrong.
Signal
A big advantage of AloSIM in Korea is if your signal is low, you can switch between the big 2 networks SKT or KT on 5G. Though in truth, both networks offer strong signal throughout, so we think you should probably stick with KT. More to follow on why in the speed section…
Speed
As we always do, we ran speed tests on every network available with AloSIM. SKT on 5G is the default network and speeds were quite disappointing, coming in at 24 Mbps, surprising considering SKT is very fast on other travel eSIMs. However, after switching over to KT, we got speeds a lot closer to what we’re looking for. KT hit almost 93 Mbps on 5G, a very close 4th place in our speed tests and suitable for regular browsing online.
Given the decent speeds on KT, we think speed is generally a pro for AloSIM. There’s just a number of faster options available in Korea.
Speed comparison:
| Provider | Ubigi | Nomad | Firsty | AloSIM | GigSky | Holafly |
| Download Speed (Mbps) | 351 | 149 | 94.5 | 93 | 40 | 6.96 |
| Upload Speed (Mbps) | 7 | 3 | 10 | 9 | 0.1 | 3 |
| 4G or 5G? | 5G | 5G | 4G | 5G | 4G | 5G |
| Fastest Network | SKT | SKT | “Firsty” | KT | “GigSky” | “Holafly” |
Price, value and offers
AloSIM pricing breakdown is as follows:
| Data | Price | Validity | Price per GB |
| 1 GB | $5.00 | 7 Days | $5.00 |
| 2 GB | $8.00 | 15 Days | $4.00 |
| 3 GB | $10.00 | 30 Days | $3.33 |
| 5 GB | $15.00 | 30 Days | $3.00 |
| 10 GB | $27.00 | 30 Days | $2.70 |
AloSIM is seemingly always priced somewhere in the middle of most eSIMs for travel and in Korea, we’d say that is more or less still the case, though it is slightly more in the mid/expensive range versus competition than it usually is.
To really understand the value, it’s worth noting that AloSIM comes with a free phone number and a small amount of internet calls and SMS with all new plans too. How much you appreciate that really will help to define whether AloSIM is decent value to you. For us, it’s nice to have, but not essential.

App
The AloSIM app is one of our favorites. You’re going to get a sleek, visually appealing app and best of all, it prominently displays all of the key information. We also like that you can switch between various currencies. Finally, you can install eSIMs via multiple methods, including directly from the app.
Anything else?
AloSIM offers a 5% cashback on all purchases loyalty scheme.

5. GigSky
Underwhelming speeds and high prices make this a tough sell in a competitive market.
Check siteThings to know
- Prices: 1GB: $6 / 3GB: $18.99 / 5 GB: $29.99 / 10GB: $27
- Discounts: No
- Services included: Mobile data only
- 4G or 5G: 4G
- Cell providers: GigSky
- Hotspot: Yes

Pros
- Strong signal
Cons
- The most expensive of all plans checked
- Underwhelming speeds
What you need to know
GigSky left us quite underwhelmed in Korea. Prices are higher than our other eSIMs tested, but speeds are slow and you’re not getting anything additional for your money.
Signal
Signal is one of the strongest points of GigSky in Korea thanks to solid performance throughout the country. In terms of the networks to use, you’re only getting one choice and it’s simply called “GigSky”, so we couldn’t tell what actual network that is. In our experience, signal was unfortunately 4G only.
Speed
GigSky will get most jobs done, you will be able to do the majority of your every day internet activities on the move with GigSky in Korea. Social, browsing, video calls all work, but you will get the odd slow down or lag and you definitely won’t be streaming in high definition.
In terms of download speeds, GigSky scored 39.6 Mbps, not super slow but it ranked 5th of 6 in our speed tests thanks to a number of great offerings elsewhere. Though with an upload speed score of 0.11 Mbps, just forget trying to upload anything and wait until you have wifi.
Speed comparison:
| Provider | Ubigi | Nomad | Firsty | AloSIM | GigSky | Holafly |
| Download Speed (Mbps) | 351 | 149 | 94.5 | 93 | 40 | 6.96 |
| Upload Speed (Mbps) | 7 | 3 | 10 | 9 | 0.1 | 3 |
| 4G or 5G? | 5G | 5G | 4G | 5G | 4G | 5G |
| Fastest Network | SKT | SKT | “Firsty” | KT | “GigSky“ | “Holafly” |
Price, value and offers
GigSky pricing breakdown is as follows:
| Data | Price | Validity | Price per GB |
| 1 GB | $6.99 | 7 Days | $6.99 |
| 3 GB | $18.99 | 15 Days | $6.33 |
| 5 GB | $29.99 | 30 Days | $6.00 |
| 10 GB | $54.99 | 30 Days | $5.50 |
There’s no getting around it, GigSky is one of the most expensive options in South Korea, with a price per GB that’s far higher than the others on our list. If we take a look at what we consider to be the sweet spot of 3 GB, you can really see the price difference.
| Data | Ubigi | AloSIM | GigSky | Nomad | Saily | Airhub |
| 3 GB | $9.00 | $10.00 | $18.99 | $11.00 | $7.99 | $7.00 |
The high prices combined with slower speeds mean that we just don’t think the value is there for GigSky in Korea.
App
When we first used GigSky towards the end of last year, we had some issues with the app crashing. They are now long gone and the app is totally functional. In general usage, we do find the app to be just a touch slow, but it’s nothing that will have too much of an influence on your experience. We would also like to see some more detail regarding the available packages.
Otherwise, everything works pretty much as it should.
Anything else?
GigSky has a loyalty scheme, which we love to see. Though it’s not explicitly explained, it works out to 5% of the purchase amount back as credit.

Pros

Cons
- Speeds are too slow to be useful
- Quite expensive
What you need to know
While Holafly offers unlimited data, the speeds are simply too slow to recommend. Prices are also on the expensive side.
Signal
One thing that Holafly does do well in Korea is signal. We generally had good signal throughout our time on Holafly, with bars usually at 2 or above out of 4. Signal is 5G and provided by “Holafly”, they don’t tell you which network that is, nor let you switch to any other networks.
Speed
Where Holafly let us down is speeds. In every day life, it’s just quite a frustrating experience. Browsing is slow, socials even slower and even basic activities like Google Maps are difficult to use.
We suspected slow download speeds and that was backed up by their score of almost 7 Mbps, it’s really too slow to achieve much with.
Speed comparison:
| Provider | Ubigi | Nomad | Firsty | AloSIM | GigSky | Holafly |
| Download Speed (Mbps) | 351 | 149 | 94.5 | 93 | 40 | 6.96 |
| Upload Speed (Mbps) | 7 | 3 | 10 | 9 | 0.1 | 3 |
| 4G or 5G? | 5G | 5G | 4G | 5G | 4G | 5G |
| Fastest Network | SKT | SKT | “Firsty” | KT | “GigSky” | “Holafly” |
Price, value and offers
Holafly pricing breakdown is as follows:
| Data | Price | Validity |
| Unlimited | $21.00 | 5 Days |
| Unlimited | $29.00 | 7 Days |
| Unlimited | $37.00 | 10 Days |
| Unlimited | $51.00 | 15 Days |
| Unlimited | $62.00 | 20 Days |
Holafly offers unlimited data with all of its packages. Whether it’s truly unlimited data is the subject of some debate online, with a number of users suggesting that Holafly slows your browsing speed down after a certain amount of data according to a fair use policy, which we do think is reasonable. We can not clarify this ourselves.
Our issue is that we saw slow speeds from the get go, so it’s hard to know if they’d been slowed any further. In terms of our own testing, we’ve never really managed to get through significant data and haven’t seen any slow down, mainly as speeds were always slow.
We would love Holafly to be a genuine option for the power users with high data requirements, but all the data in the world isn’t really worth it with slow speeds. For those users, Firsty offers 2 GB a day packages and this is how they compare:
| Days | Firsty | Holafly |
| 5 Days | $13.53 (Approx) | $21.00 |
| 7 Days | $18.94 (Approx) | $29.00 |
| 10 Days | $27.06 (Approx) | $37.00 |
| 15 Days | $35.72 (Approx) | $51.00 |
| 20 Days | $47.62 (Approx) | $62.00 |
With Firsty offering a speed of 94 Mbps and Holafly 6.96, we have to say that Firsty offers the better value for those users in our opinion.
App
The Holafly app looks relatively clean and fresh, is now much more functional and is generally a lot easier to use than it once was, with features such as login via Google now working properly.
Anything else?
No traditional loyalty program to mention unfortunately.

Ubigi is the fastest eSIM we tested in Korea by a long way, blasting through our speed test at 351 Mbps. This is the fastest speed we’ve tested anywhere so far, over twice as fast as the second place Nomad. Nomad came in at a very respectable 149 Mbps, enough for most of your browsing needs. In third place, Firsty with 94.5 Mbps, enough to help you get through your 2 GB daily limit.

What eSIM is the best value in South Korea?
With the best combination of super fast speeds and very reasonable data pricing for packages over 1 GB, this is an easy win for Ubigi.
🏅 Winner: Ubigi
What eSIM is the best for short-term travel in South Korea?
This really depends on how short-term we’re talking. If 1-2 days, we think Firsty and their fast plan makes the most sense for short-term travel. 2 days with 2 GB of data per day at 94 Mbps speed, all for about $5.44 is a great deal. Otherwise, we’d recommend Nomad or Saily.
🏅 Winner: Firsty
What eSIM is best for heavy data users in South Korea?
Another vote for Firsty. Their 2GB per day limit is plenty, even for us. With speeds of 94 Mbps, you can use it for the sort of things that you’d want to use such a high data limit on. For us, that’s streaming, video, video calls etc.
🏅 Winner: Firsty
What eSIM is best for budget travelers in South Korea?
Saily is the cheapest eSIM in Korea at every level. We’d recommend Saily for budget travelers in Korea.
🏅 Winner: Saily
What eSIM is best for travelers needing calls and SMS in South Korea?
We have not yet found a travel eSIM that offers calls and SMS in Korea. We’d therefore recommend AloSIM and their Hushed service. They offer a small amount of calls and SMS over internet data.
🏅 Winner: aloSIM
