Tips to buy the best Korean travel sim with cheap price in Vietnam

If you have had experience of traveling to other countries, you probably already know that buying a Korean Tourist Sim is absolutely essential for you to be able to access the internet and stay connected with friends and family. Most importantly, don’t get lost in a strange place! 😅😅

Sim2go.vn will cover all the important details about the different travel sim cards in Korea, as well as all the aspects that you need to keep in mind to choose the right one for you, fit your wallet.

1. Korea’s three largest mobile carriers

South Korea has three telecom service providers: SK Telecom, KT (Olleh) and LG U+. SK is the largest provider with more than 27 million subscribers, while KT has more than 16 million. The coverage of both SK Telecom and KT is very good on both 3G and 4G networks. South Korea was one of the first countries to roll out a 5G network, but it was not accessible to prepaid Sim cardholders.

Each network operator will have a preferential price and different packages to suit the needs of tourists.

The average download speed is 40 Mbps, SK Telecom even reaches 65 Mbps. Upload speeds are also lightning fast. You’ll enjoy access speeds of at least 10 Mbps and peak speeds of up to 15 Mbps with SK Telecom and LG U+ networks.

2. Some basic things to keep in mind before choosing a 4G South Korea travel sim card

Over the years, the size of Sim cards has decreased. Older models use standard size Sims, newer phones use Micro-Sim and Nano-Sim. Like most Sim cards used in daily life, the Korean travel 4G Sim also integrates 3 sizes such as Nano, Micro and Standard on 1 Sim card, making it easy to install and remove.

3G/4G data/data-only SIM card will be the perfect choice if you don’t need a SIM card to include voice calls and text messages while you’re in Korea. Sim data cards usually provide unlimited data access, so you can easily use apps like WhatsApp, Zalo, Viber, FB… to make calls and send messages.

Alternatively, the other options Data sim cards + Voice Call cards are only slightly more expensive and allow you to get a phone number so you can make and receive calls during your visit to South Korea.

3. Make sure your phone is unlocked

Korean 4G travel sim cannot be used for network locked phones (jailbroken iPhone phones, non-international versions). This is important to note for those of you who use a network-locked phone. Make sure your phone is unlocked.

4. Choose a short-term or long-term 4G Korean travel sim?

All prepaid Korean tourist sim cards can be used within a certain number of days (5 days, 8 days, 15 days,…). This period starts when you activate your Sim and in most cases it cannot be extended.
Based on your schedule, choose the right Sim card for you. If you need a Sim for longer than the period provided, you may be able to purchase 2 Sim cards to use alternately. However, not all network providers in Korea allow buying multiple Sim cards on the same person.

5. Where to buy Korean 4G travel sim?

You can buy a Korean 4G Sim in Vietnam or buy it directly at the airport, at convenience stores in Korea. Depending on your needs and wallet, you can choose the most suitable product for you.

5.1. Buy 4G Sim Card in Korea

To buy a Korean 4G Sim or a Korean tourist sim, the most common option is to buy it at the airport. After picking up your luggage, you go to the airport service counters and you will see a variety of carriers and freely choose. There are many telecom service counters from different telecom companies (SKT, KT, LG U+) but KT has absolute dominance in terms of Travel Sims for foreigners.
