No.1 MicroEsim
Of the best eSIMs for international travel, MicroEsim's plans are pretty flexible, from 1 to 30-day durations, with different data options countable in daily or total. The prices start at $0.80, and once the high-speed allowance is consumed, you can still stay connected at reduced speeds of 384kbps. No worries about disconnection. In cooperation with the reliable local operator SKT of South Korea, it will also provide stable and fast 4G / LTE / 5G speeds.
Furthermore, MicroEsim offers comprehensive coverage all around South Korea, much better compared to competitors. On the other hand, for travelers visiting more than Korea, like Singapore and Malaysia, MicroEsim still offers bundled packages, such as the Asia 10 Regions eSIM, making it more cost-effective and hassle-free.
It's easy to use because you can easily order online and activate it via a QR code, with no eKYC required. In addition, it supports hotspots that allow sharing your connection with other devices, hence saving on roaming charges. Overall, it is the first option when choosing the best eSIM.
Here are the price packages from MicroEsim for Korea:
| Destinations | Duration | Data Plans | Price（USD） |
|---|---|---|---|
| South Korea eSIM | 1-30 days | Daily 500MB /Total 20 GB/Unlimited | $0.80-$50.90 |

No.2 Airalo South Korea eSIM
Airalo is one of the well-known eSIM providers and officially the world's very first eSIM marketplace. It offers two plans for South Korea that can be subscribed to for either 10 or 30 days with unlimited data usage. However, the speed throttles down to 5 Mbps after using 3GB every day. The starting price is $32.00, and it uses the LG U+ network.
While Airalo is quite extensive and has wide coverage and unlimited data, it comes with some drawbacks. It requires eKYC, which could be painful for many users. The worst thing is, it does not work on Pixel devices if you plan to use an eSIM card on Android.
Here are the price packages from Airalo for Korea:
| Destinations | Duration | Data Plans (up to) | Price(USD) |
|---|---|---|---|
| South Korea | 10/30 days | Unlimited | $32.00/$62.00 |
No. 3 Nomad South Korea eSIM
Although users do report issues related to connectivity and speeds at times, Nomad just cannot be left out when it comes to one of the best eSIMs for Asia. Nomad is a fairly reliable eSIM provider available in the market. It offers two types of plans for eSIM Korea: Regular plans and Day plans, which range from 7 days to 45 days for 1 GB to 20 GB, and from 1 day up to 10 days, with up to 3 GB per day at unlimited 512kbps, respectively.
Nomad partners with local operators SKT, KT, and LG Uplus and claims to support 5G; however, according to users, most of the time, it does not give the speed as suggested. Unlike MicroEsim, once you have used up your data, you will be cut off and will need to buy more plans; no add-on data or days are possible. In case more data is needed or if you want to extend the plan, it is quite a headache, as a new plan will have to be purchased and activated after the first one expires.
Here are the price packages from Nomad for Korea:
| Destinations | Duration | Data Plans | Price(USD) |
|---|---|---|---|
| South Korea Regular Pian | 7 days | 1 GB | $6.00 |
| South Korea Regular Pian | 30 days | 3 GB | $11.00 |
| South Korea Regular Pian | 30 days | 5 GB | $14.00 |
| South Korea Regular Pian | 30 days | 10 GB | $17.00 |
| South Korea Regular Pian | 45 days | 20 GB | $24.00 |
| South Korea Day Plans | 1 days-10 days | 500MB/day+unlimited 512kbps - 3 GB / Day + Unlimited 512kbps | $2.50-$110 |
No. 4 GigSky South Korea eSIM
GigSky is a top eSIM provider based in Silicon Valley, the first eSIM partner with Apple. This will be a great option if you are going to use eSIM on an iPhone. It offers South Korea-specific plans but also includes Korea plans, such as Asia Pacific plans, World Plans, and Cruise + Asia Pacific plans. The price starts at $4.99 for 1GB for 7 days.
It offers one of the unique features: a 100MB free trial that lasts for 7 days. Furthermore, GigSky collaborated with the Asiana Airlines Group to provide data in-flight, and you can stay online even inside a plane, but at a pretty pricey cost of $3.99 for 1 GB for 7 day, so you need to remember to keep a tab on consumption at all times. On the downside, GigSky does not have any unlimited data plans, and the pricing turns out to be a little more expensive in comparison with other eSIM providers.
Here are the price packages from GigSky for Korea:
| Destinations | Duration | Data Plans (up to) | Price（USD） |
|---|---|---|---|
| South Korea | 7-30 days | Total 1 GB-Total 10GB | $3.99-$24.74 |

Gigsky South Korea esim, there are recent promotions for 3/5/10GB, with a discount of about 20%
No. 5 Airhub South Korea eSIM
Airhub was founded in 2020, therefore, it is a rather young company. It supports all eSIM-enabled devices, so there will be no need to worry about your eSIM device compatibility. Airhub offers some plans for South Korea exclusively, along with global plans, including Korea. They range from 5 days to 30 days and from 4GB to an unlimited amount of data, at $7.50 as a starting point.
While speeds vary between plans, some offer 5G, with coverage provided by the SK Telecom network. While this sounds great, many customers have had issues monitoring data usage, meaning you'll have to track this yourself. There can be a trust issue with a new brand, but if the price is right, maybe give it a try.
Airhub is slightly more expensive than Microesim, but the price is a good advantage compared to other brands.
Here are the price packages from Airhub for Korea:
| Destinations | Duration | Data Plans (up to) | Price（USD） |
|---|---|---|---|
| South Korea | 5/10 days | Unlimited | $15.50-$21.50 |
| South Korea | 30 days | Total 33 GB | $38.50 |

No. 6 Jetpac South Korea eSIM
Singapore-based Jetpac eSIM offers plans starting from 4 days to 30 days and data options from 1GB to 40 GB. New users can purchase at a discounted price of just $1 for 1GB for 4 days, allowing access to speeds of 3G and 4G. Although these plans sound pretty ordinary, it is the first eSIM provider to set itself up with front-of-queue lounge access for travelers if their flight is delayed by over 60 minutes. If this is a perk that is important to you, then Jetpac can very well be worth it.
| Destinations | Duration | Data Plans (up to) | Price（USD） |
|---|---|---|---|
| South Korea | 4-30 days | Total 40 GB | $1.00 - $75.00 |

Final Verdict
Having 6 eSIM options to select from, choosing the right one can be a bit baffling. Each carries specific pros and cons, but if we go based on something that balances their price, data amount, speed, and bundle extras like hotspot capabilities, it will point in only one direction, and that would be MicroEsim.
Whether it is from the price or the diverse specifications and data, there is no doubt that Microesim is very outstanding, but at the same time, Microesim also has a disadvantage, that is, the brand influence is not enough, and it is difficult for users who have never used the brand to trust it immediately. But I still highly recommend this brand, because after you use it, you will find that Microesim is really trustworthy.
