Public WiFi in South Korea
Public WiFi is a great option in South Korea to avoid spending too much on internet usage, but it’s not the safest option.
When you arrive at places like the Incheon International Airport, you can use free WiFi. This also applies to restaurants, malls, and train stations across the country.
However, free WiFi is not the safest way to get mobile internet. Since it’s free, everyone can access it, which makes your personal and financial information unsafe. Plus, chances are you won’t get high-speed internet with a free hotspot.
If you want to use free WiFi, do so for a short period of time, such as sending a message, searching for an address, or something similar, but avoid using it full-time on your trip.
Pocket WiFi in South Korea
Pocket WiFi is useful for group travel or high internet usage, but it comes with high rental fees and potential data limits.
However, using a pocket WiFi in South Korea can cost you even more than using roaming, as renting one of these devices can cost $49/day without including delivery fees and other add-ons, like portable charges.
But if you need high-speed internet to share with others or to connect to other devices you own, using Holafly Plans is a great alternative to getting WiFi in South Korea.
For $64.90/month, you get unlimited data, unlimited hotspot data, 24/7 customer support, and coverage in over 170 destinations with one eSIM, and it costs less than international roaming especially with heavy internet usage.
What is the best way to get internet in South Korea?
South Korea has one of the highest internet penetration rates globally, with over 90% of the population being online users thanks to excellent internet infrastructure.
Whether you’re a tourist or a digital nomad, your internet usage needs will vary, but having flexible, secure internet access is key. A travel eSIM gives you just that, as it can include unlimited data, up to unlimited hotspot data, excellent coverage, and a price that is way lower than roaming.
While other options, like a prepaid SIM card, have a similar price, most modern smartphones leave the SIM card tray aside, meaning some devices won’t work with them at all.
Roaming and pocket WiFi devices limit internet usage a lot, and since these are so expensive, it’s better to avoid them.
Here’s a quick view of every option and how they work:
Option | Hotspot sharing | Security | Support | SIM unlock required | Physical installation |
---|---|---|---|---|---|
Pocket WiFi | Yes | Private network | Rental company | No | Yes |
Local SIM | Fast | Private network | Mobile provider | Yes | Yes |
Roaming | Varies | Private network | Home provider | No | No |
eSIM (Holafly) | Yes | Private network | 24/7 | Yes | No |
So, using an eSIM for South Korea is a cost-effective and secure way to get internet access, and you only need an eSIM-compatible phone
