SIM Card vs Wi-Fi Router: Which Mobile Internet Option Should You Use When Traveling in South 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 router, or WiFi Egg.

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 WiFi router.

EG SIM card is recommended as most the popular prepaid SIM card in Korea, which provides high-quality voice calls and high-speed mobile data and text everywhere in Korea. For details, click here.E_AbouEGSIMCard

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

Once you purchase the EG SIM card, you will receive a new local (Korean) phone number while using your own mobile phone. Therefore, the best thing about using EG SIM card is that you will be able to communicate with the locals and receive international calls as well! This is why the EG SIM card is ideal for travelers on a business trip or short sojourn who need to make local calls in Korea.

*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.korea-sim-card-mobile-voiceFor 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 Router

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

If you are a traveler who does not need to use the voice calls and text messages but needs loads and loads of mobile data for surfing the internet and send large files of photos and videos online (and of course, avoid a bill shock from costly roaming service), using a WiFi router, or WiFi Egg, is highly recommended. For more details on WiFi Egg, click here.

Pocket-WiFi-Korea-LTEAccording to a research, the average daily usage of mobile data of travelers is 125MB/day. While the EG SIM card provides 1GB of mobile data and the 3G service for up to 30 days, the WiFi Egg provides 1GB a day.

For those who are wondering how much 1GB a day is, just think of it as sending/receiving 28,000 emails, shooting 2,000 Instagrams, or making 6,000 posts on Facebook.

Therefore, if you think about using 1GB for 30 days, the amount of mobile data provided by EG SIM card is comparatively smaller than that of the WiFi Egg. If you are using the WiFi Egg, though 1GB is still a lot of data, try to avoid heavy downloading and uploading online because you do have to pay extra charges (US$ 0.02 / MB) when you exceed the data limit of 1GB. 😉

Share WiFi with your travel buddies with 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 or in a small group of buddies. 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 & How to Purchase/Rent Sim Card and Wi-Fi Router

Travelers can purchase a prepaid SIM card online and then pick it up at places such as Incheon International Airport.korea-sim-card-mobile-voiceIf 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 via Korea’s #1 Travel Shop, Trazy.com.korea-sim-card-unlimitedFor 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.prepaid-sim-cardWith this SIM card plan, you can enjoy phone calls, text messages and 4G/LTE data for up to 90 days.
