What is South Korea SIM Card?
A SIM card, or Subscriber Identity Module card, is a small, removable smart card essential for mobile phones to connect to a cellular network. It stores the user’s information, such as their mobile number and network authorization data, which are crucial for identifying and authenticating the subscriber on the network. SIM cards allow devices to access the cellular network to make calls, send texts, and use mobile data. They can also store contact information and text messages.

Which is Better in South Korea? SIM cards, eSIMs, or Wi-Fi routers

When visiting South Korea, you have three primary options for staying connected: SIM cards, eSIMs, and Wi-Fi routers. For most visitors, a data-only SIM card suffices, allowing access to the internet and the use of essential apps like Google Maps or social media. However, if your itinerary involves more activities like take taxi online or book restaurants online, a SIM card with a phone number might be necessary.
South Korea SIM Cards
SIM cards are a popular choice because they offer fast and reliable internet by tapping into local network speeds. They are also more cost-effective compared to international roaming charges. You won't need to charge a SIM card, but your phone must be unlocked to use it.
Many local services, such as taxi apps (e.g., Kakao T) and restaurant waitlists, require communication via a local phone number, often for booking or receiving notifications. Tourist SIM cards that include both data and a phone number are available and are priced comparably to data-only SIMs.
South Korea eSIMs
eSIMs provide a hassle-free experience as they do not require physical card swaps. They're becoming increasingly popular for their instant connectivity upon arrival.
However, keep in mind that eSIM compatibility is limited to certain smartphone models (often the latest model).
South Korea Wi-Fi Routers
Wi-Fi routers are ideal for groups as they allow multiple devices to connect at once. The downside is that they need to be charged and can be cumbersome to carry around.
For a straightforward decision, a SIM card or eSIM is recommended depending on your phone's compatibility. Consider a Wi-Fi router if traveling in groups or needing multiple connections.
Here’s a table for each option:
Connection Type | Best For | Main Features | Considerations |
SIM Card | Staying in one place with an unlocked phone. | High-speed data, direct carrier connection. | Requires an unlocked phone, potential compatibility issues. |
eSIM | Frequent travelers, using multiple carriers. | No physical card needed, can host multiple profiles. | Limited device and carrier compatibility. |
Wi-Fi Router | Groups needing shared connectivity. | Connect multiple devices, no device compatibility issues. | Bulky, requires charging, performance varies by area. |
