How To Buy A SIM Card or Rent A Pocket WiFi for Korea Travel

It’s hard to imagine traveling in a foreign country without the internet these days.
South Korea is first in global rankings of ICT penetration including internet speed.
If you search “Where to buy a SIM card or Pocket WiFi for travel in Korea?” you will see too much confusing and unhelpful information.
Should I use an LTE SIM card or a Portable WiFi?  What are the terms and the price? Is it the cheapest option? Where can I buy a SIM card for Korea? and where can I pick it up? It’s a hassle to find the answers to all the questions.

Staying connected during your travel in Korea doesn’t have to be complicated.
Here are the best ways to do so 🙂

How to buy a SIM card or Pocket WiFi for travel in Korea

Which is better, SIM or Pocket WiFi?

As mentioned, you can use the data by changing the SIM card on your phone or renting a pocket WiFi egg as well.
To determine which is best for you, consider these questions:
1. How many people in your group will be connected to the internet?
2. How long is your trip?

You only can use your SIM card in a phone but people can connect up to 3 devices on the same pocket WiFi. (Service providers say up to 5 people can connect, but if you try it, you will understand why I say you can connect up to 3 people.)
Using a SIM card is easy and private. You don’t need to return it. They also give a discount for every additional day you buy.

A Pocket WiFi is good for two or three people and also cheaper than a SIM card.
However, you always have to bring it with you and recharge it regularly. You also need to return it when you leave. They provide a huge discount from the 6th day.

Hopefully, this information has helped you determine what works best for your trip!
