SIM Card vs WiFi Egg: Which to Use in Korea?

SIM Card Vs WiFi Egg: Compare the two most popular mobile options in Korea!

Do you want to share your travel experiences real time on Facebook and Instagram? Or do you have to make calls and send text messages while traveling in South Korea?

Among many options for you to get accessed to the mobile internet and stay connected in Korea, here are the two most popular options that are commonly used by travelers: Prepaid SIM Card and WiFi Egg, or WiFi Router.

See which option is ideal for you based on your needs and stay connected in mobile-friendly South Korea!

1. Prepaid SIM Card


Need to make voice calls and use mobile data & SMS? Purchase a prepaid SIM Card!

If you are a traveler who needs to make local and international calls and also wants to use mobile data and text while traveling in South Korea, purchasing a prepaid SIM card is a better option for you instead of renting or buying a portable WiFi router.

Need a local Korean number? This prepaid SIM card is what you are looking for.

The prepaid SIM card above ideal for travelers who need to make local calls in Korea. You will receive a new local (Korean) phone number while using your own mobile phone and be able to make or receive local/international calls.

*Possible Downside
Do keep in mind that since you will be using a new Korean number, you will have to go through the hassle to tell your friends, family and acquaintances back at home about your new number.

For those who don’t want to go through the hassle, here’s a small tip for you. Along with the mobile device that you are using right now, bring another one that you do not use anymore. Register and insert the SIM card in the old device and use the new Korean number. This way, you can easily make local calls by just using your old phone.

2. WiFi Egg

Need to use loads of mobile data every day? Rent a WiFi Egg!

If you do not need to use the voice calls and text messages but needs loads of mobile data for heavy downloading and surfing, using a WiFi Egg, or a portable WiFi Router, is highly recommended.

According to a research, the average daily usage of mobile data of travelers is 125MB/day.

While the EG SIM card provides 1GB of 3G mobile data for up to 30 days, the WiFi Egg provides 1GB a day.

Using 1GB a day is like sending/receiving 28,000 emails, shooting 2,000 Instagrams, or making 6,000 posts on Facebook.

Taking this account, the amount of mobile data provided by EG SIM card is relatively smaller than that of the WiFi Egg.

If you choose to use the WiFi Egg, try to avoid heavy downloading and uploading online! There are extra charges when you exceed the data limit of 1GB (US$ 0.02 / MB). 😉

Share WiFi with your travel buddies with a WiFi Egg

WiFi Egg can connect up to 5 people simultaneously, which makes it perfect for you if you’re traveling with friends and family. If you do share the router with your friends, you can share the cost as well.

*Possible Downside
The battery life of the WiFi Egg lasts about 5-7 hours on a single full charge, which means that you have to carry around the battery charger when traveling. Plus, the battery life drains quicker when the WiFi Egg is used simultaneously. So make sure that you have an extra charger to charge the Wi-Fi router device. 

3. Where to rent or buy

Travelers can purchase a prepaid SIM card online and then pick it up at various locations, including Incheon International Airport.

If you want to save your time and stay connected as soon as you arrive at the airport, we advise you to purchase the SIM card online.

For those who don’t need to use any voice calls or SMS and are going to stay temporarily in Korea, the data-only plan is an ideal choice. Booking a mobile data-only SIM card at a discounted price is available here.

On the other hand, if you are planning on staying in Korea for more than a month, then this long-term prepaid 4G-LTE SIM card is a better option than the data-only plan.

With this SIM card plan, you can enjoy phone calls, text messages and 4G/LTE data for up to 90 days. For more info, click here.

This SIM Card is highly recommended for long-term travelers and international students visiting Korea for a student exchange program.

Similar to the prepaid SIM card, it is advisable to rent WiFi Egg online in advance and then pick up the egg at the airport.
