South Korea eSIM: a local guide
Seoul and the capital area
A large share of South Korea's people live in the Seoul capital area, which takes in Incheon and the cities of Gyeonggi Province such as Suwon and Seongnam. This is where most offices, universities and apartment complexes are, and coverage is dense above ground and in most of the places people commute through. A year-long data eSIM gives you a working line from your first day, while your own SIM stays in the phone for calls and verification codes.
Busan, Daejeon and the rest of the peninsula
Beyond the capital, Busan, Daegu, Daejeon, Gwangju and Ulsan are major cities with dense coverage, and Jeju Island is well served around Jeju City and Seogwipo. The east of the country is mountainous, with the Taebaek range running through Gangwon Province, and signal can thin out in the deeper valleys and on remote ridges. Small islands off the south-west coast can have gaps too. Out in the farming country of the Jeolla and Gyeongsang provinces, towns are well connected and the stretches between them are mostly covered as well.
Who it suits in Korea
- International students at universities in Seoul, Daejeon and Busan who want data before they have the residence paperwork many local plans ask for.
- English teachers on contracts at schools and academies.
- Professionals posted to company offices in Seoul or the industrial cities of the south-east.
- Remote workers who want a hotspot as a second line beside home internet.

What our customers say
Feedback from expats, residents and remote workers using the same package.
“Fast everywhere I have tried it. I keep my local number for calls and use this for everything else.”
“Non-PTA iPhone, installed in five minutes, and the 4G has been steady ever since. Hotspot for the laptop all day with no slowdown.”
“A whole year of unlimited data for one payment is unbeatable. They confirmed my device on WhatsApp before I paid, which I appreciated.”
“I was sceptical but it is exactly what they said. Good signal everywhere I have been, including on the motorway.”
“Really good value. Activation took closer to half an hour rather than ten minutes for me, but the team stayed on chat the whole time.”
“Met them in person, paid, and had it running before I left. Straightforward, and no paperwork at all.”
One payment of $232 covers twelve months of unlimited data in South Korea, about $19.33 a month. There is no monthly bill, no contract and no automatic renewal. Buying 10 or more in one order? The reseller rate is $58 per eSIM.
Yes. It covers the whole of South Korea, not only Seoul: the cities, the smaller towns and the roads between them, wherever our partner network has signal. As on any network, coverage is thinner in remote and sparsely populated areas. Tell us the town you have in mind and we will tell you what to expect there before you buy.
No. Each eSIM covers one country completely, and the South Korea eSIM works only inside South Korea. For Japan you need a Japan eSIM; a modern phone holds both profiles at once and switches between them in Settings.
Yes. Hotspot is included and not metered separately, so you can run a laptop, a tablet or a TV from your phone anywhere in South Korea. Tethered data is treated like any other data, under the network operator's Fair Usage Policy.
One package: a 12-month unlimited-data eSIM for the country you choose. It covers the whole country, not just the big cities, with unrestricted hotspot use, and takes about five minutes to set up. We supply eSIMs for 200 countries; pricing in some of them varies with local network conditions, and we confirm the exact price before you buy.
In very rare cases the connection may appear to pause. The fix is instant: turn OFF mobile data, wait 5 seconds, then turn ON mobile data again. This resolves it almost every time.
Datainfinite is an independent eSIM reseller. We do not own a mobile network: we buy data wholesale from licensed B2B carriers such as Telnyx, 1GLOBAL, Telna and BICS, choose the best route for each country, and handle setup and 24/7 support ourselves. Your eSIM runs on local partner networks in the country you choose.
Try the following, in order:
- Turn Airplane Mode ON, wait 10 seconds, then OFF
- Restart your device once
- Make sure Data Roaming is enabled
- If it persists, contact our support team, we are here 24/7
Your phone needs to support eSIM and must not be carrier-locked or JV (Joint Venture) restricted — a JV handset is SIM-locked to a specific foreign carrier under contract. Most iPhones from the XS onward, recent Samsung Galaxy and Google Pixel models qualify, send us your device model on WhatsApp and we will confirm before you buy.
Message us on WhatsApp or email us. We confirm your device is compatible, confirm the price for your country, and send your eSIM QR code straight to you, all we need are your contact details.
No. Each eSIM is for one country and covers all of it: the cities and towns across that country, wherever our partner network has signal. If you need a second country, that is a second eSIM. Tell us where you are going and we will set up the right one.
No. The eSIM sits alongside your existing SIM and carries data only, so calls and texts keep arriving on your normal number. You simply set Datainfinite as the default data line.
Your eSIM may not work in China due to several factors. Check if your device is compatible with local networks, ensure that the eSIM is activated correctly, and verify that you have a valid data plan. Additionally, confirm that airplane mode is off and that network settings are properly configured.
Handsets bought in mainland China or Hong Kong are the usual cause: those models ship with dual physical SIM and no eSIM hardware at all. Send us your exact model on WhatsApp and we will confirm before you buy.
