FAQs about Connectivity Options in Korea

What is the optimal choice for my trip to Korea: SIM card, eSIM, or WiFi?

When deciding between a SIM card and renting a WiFi device, choose based on your specific needs. If you’re traveling in a group or wish to connect multiple devices like laptops and tablets alongside your phone, a WiFi device is ideal. It allows multiple devices to share a single connection, offering convenience and value. For solo travelers or those preferring the simplicity of using their phone without the need to carry additional devices, a SIM card is the way to go. It offers direct connectivity in your personal device. If your phone supports eSIM technology, opting for an eSIM can be the most convenient choice, eliminating the need for physical SIM swaps while providing the same benefits.

What are the data limits for SIM and eSIM plans?

Data limits for SIM and eSIM plans can be broadly categorized into Unlimited and Limited types. However, understanding the specifics of these data limits is crucial. Data limitations can be divided into daily usage limits, such as 1GB per day, or total usage limits over a set period, like 3GB over 5 days. In our comparison table, the “4G Limit” indicates the amount of high-speed data available, while “After 4G” refers to the reduced speed once the high-speed data cap is reached. This is vital because, even under “Unlimited” plans, the speed restriction after reaching the high-speed data limit, often set at 128kbps, can significantly hinder internet usability. Relying solely on the term “Unlimited” without understanding these specifics may lead to dissatisfaction due to unexpected speed limitations.

How do I check if my Android device supports eSIM?

eSIM compatibility varies by manufacturer and model. While some devices are marketed as eSIM-capable, regional variations or carrier-specific models may lack eSIM functionality. Android’s open-source nature allows manufacturers and carriers to modify it, potentially affecting eSIM support. To check your Android device’s eSIM capability:

Samsung Galaxy:
1. Open the Settings app and select Connections.
2. Tap SIM Manager.
3. If you see an “Add eSIM” option, your device supports eSIM.

Google Pixel:
1. Open the Settings app and go to Network & Internet.
2. Tap the “+” sign next to SIMs.
3. If there’s a “Download a SIM instead?” option, your device is eSIM-ready.

Please note, these steps might vary based on your device and software version. For the most accurate information, consult your device’s manufacturer, vendor, or carrier.

How do I check if my iOS device supports eSIM?

iPhones support eSIM from the iPhone XS model onward, but compatibility might be affected by the region or carrier lock status. To verify eSIM support:
1. Open the Settings app and navigate to General.
2. Tap About.
3. Press the Model Number to switch it to an AXXXX format.
4. Ensure the Model Number does not indicate a device from China mainland, Hong Kong, or Macao, as these regions may have different eSIM capabilities.

To Check Carrier Lock Status:
1. Still in the About section, scroll to find the Carrier Lock field.
2. If it reads “No SIM restrictions,” your iPhone is unlocked and more likely to support eSIM functionality.

Remember, the best source for confirmation on eSIM support is directly through your phone’s manufacturer or your mobile carrier.

Can I use my existing mobile number with a Korean SIM or eSIM?

No, you’ll be assigned a temporary Korean number. However, apps like WhatsApp can continue using your original number.

What happens if I exceed my data limit on a SIM or eSIM plan?

If you exceed your limit, your internet speed may be throttled to a slower speed (See the speed of After 4G in the table), depending on the plan’s policy.

Can I purchase a SIM, eSIM, or WiFi device before arriving in Korea?

Yes, you can pre-order these online and choose to have them delivered or available for pickup upon arrival. If the location is ‘Delivery’, the products is available for online purchase and delivery.

Is it possible to top up or extend my SIM/eSIM data plan?

Many prepaid SIM and eSIM plans can be topped up or extended via the provider’s website or app. For the voice topup, check the Voice topup option in the filters.

What coverage can I expect with Korean SIM/eSIM cards?

Korea has excellent cellular coverage nationwide, including most rural areas, with all major providers offering extensive 4G and increasingly 5G networks.

Are there any special requirements for renting a WiFi device in Korea?

You’ll need a credit card for security and an ID for verification. The process is usually straightforward.

How easy is it to find public WiFi in Korea, and is it reliable?

Korea offers widespread public WiFi in urban areas. It’s generally reliable, but a SIM/eSIM or WiFi device is recommended for constant connectivity.

Can I use a Korean SIM/eSIM for calls and texts, or just data?

Most plans focus on data, but there are options that include local calls and texts. Set the Data/Voice option to ‘Data+Voice’ to see the voice available options.

What should I do with the SIM card or WiFi device after my trip?

For SIM cards, you can simply dispose of them. For rented WiFi devices, return them as per the provider’s instructions, often at the airport or via mail.
