Frequently Asked Questions
Most recent smartphones support eSIM, but you should always double-check:
On iPhone, go to Settings → General → About and look for an EID number. If you see EID, your iPhone supports eSIM.
On Android, go to Settings → About phone and look for eSIM, SIM manager, or an EID field.
Your device must also be network unlocked to use an international eSIM.
If you are not sure, you can share your phone model with Gohub support, and we can help you confirm compatibility.
The safest flow is:
Purchase your South Korea eSIM 3 to 7 days before departure while you have stable Wi Fi.
Install the eSIM profile on your phone before you fly, but keep the line switched off.
Activate mobile data after landing in South Korea so your validity period starts at the right time.
This way you arrive in South Korea ready to connect and avoid last-minute stress at the airport.
No. A travel eSIM profile is designed for one device only:
Once an eSIM is activated on a phone, it cannot be moved or reused on another device.
If you change phones or want to use data on a second device, you will need a new eSIM or use a hotspot from the main device.
For families or groups, each person should have their own eSIM or share a connection via hotspot.
South Korea’s major operators (such as SK Telecom, KT and LG U+) all run strong nationwide networks, especially in cities and along main transport routes.
Gohub does not rank one carrier as “best” because coverage can vary by location, building, and device. Your South Korea eSIM will automatically connect to the local partner network used for that plan, which is chosen to give reliable everyday coverage for most travelers.
If you need detailed signal maps for a very specific area, it is best to check the official coverage maps of each operator.
In South Korea, 4G/LTE is very strong and is the main network most travelers use.
5G service is available in many busy areas, especially in big cities such as Seoul, Busan and Incheon, but:
5G availability depends on your device model, local 5G bands and exact location.
Your Gohub South Korea eSIM can use 4G/5G where available, and your phone will automatically choose the best signal it can find.
If you must have 5G, please check that your phone supports South Korean 5G bands, and be aware that the network may still switch back to 4G in some spots.
Coverage is very good in Seoul, Busan, Incheon, Daegu and other major cities, and in most towns and transport hubs.
In rural areas, mountain regions or on Jeju Island:
You can usually get signal near towns, tourist spots and main roads.
Signal can be weaker or less stable in remote villages, mountain trails or deep valleys.
For safety, download offline maps in advance and do not rely only on mobile data in remote outdoor areas.
It depends on your usage, but these ranges work for most travelers:
Light use (messages, maps, some browsing): about 1 GB per 3 days.
Normal use (social media, map navigation, food searches, some video): around 1 to 2 GB per day.
Heavy use (HD video, music streaming, frequent uploads): 3 GB or more per day.
Rough guide:
7 day trip:
Light user: 3 to 5 GB
Normal user: 7 to 15 GB
14 day trip:
Light user: 5 to 8 GB
Normal user: 15 to 30 GB
If you are unsure, choose a plan slightly larger than your estimate to avoid running out of data.
Yes, hotspot is supported on most South Korea eSIM plans, as long as:
Your phone supports tethering/personal hotspot, and
You stay within the data and fair usage limits of your plan.
Hotspot is useful for sharing data with a laptop or another phone, but it can consume data faster than using the phone alone.
A standard South Korea data-only eSIM:
Does not include traditional voice calls or SMS.
You can still call and message using apps such as WhatsApp, Messenger, FaceTime, LINE or Zoom over data.
It usually does not support SMS verification for banking or government services, so keep your home SIM active if you need those codes.
Some plans may include voice or SMS. Always check the plan details carefully before purchase.
Yes, your South Korea eSIM can work on KTX and other inter city trains:
There is often good coverage when the train passes through or near cities and large towns.
Signal may drop briefly when the train goes through tunnels or remote sections.
For long rides, you can combine train Wi Fi (if available) with your eSIM for more stable connectivity.
If your South Korea eSIM does not connect after landing, try these steps:
Turn on data roaming for the eSIM line.
Set the eSIM as your primary data line in mobile data settings.
Restart your phone and wait a few minutes for it to search the local network.
Check that APN and network selection are set to automatic.
If you changed any settings manually, reset them to default and try again.
If it still does not connect, contact Gohub 24/7 human support via app, email or chat. Share a screenshot of your SIM settings and we can guide you step by step.
