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 all-in-one prepaid SIM Card!

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

You will receive a new local (Korean) phone number while using your own mobile phone and be able to make or receive local calls.

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

*Tip

For those who don’t want to go through the hassle, bring another mobile phone that you do not use anymore along with the phone that you are using right now. Register and insert the SIM card in the old device and use the 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 need loads of mobile data for internet, 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.

The WiFi Egg usually 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 into account, the amount of mobile data provided by 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. 😉

Share WiFi with your travel buddies with a WiFi Egg

WiFi Egg can connect up to 5 people simultaneously, which makes it perfect 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 or Wi-Fi router 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 or Wi-Fi router online.

  • Prepaid Sim Card – Data Only

If you want to make local calls and send text messages on top using the mobile data, short-term sim card is ideal.
