There are multiple ratings, ranging from one to five stars, but what are the criteria for each rating, and how do they differ in terms of service and amenities? This article will provide the definitions and standards of hotel ratings from one to five stars (including domestic and international differences), the specific differences in service, facilities, and hospitality, typical hotel chains for each rating, market prices for accommodation (including domestic and international differences), how to choose a rating based on the intended use, and an analysis from a real estate developer's perspective. This article explains, in an accessible and commercial manner, the impact of hotel ratings on towns and regions.★

The SIM card is very easy to use, and the internet was very stable everywhere we went, including outside of Seoul! I'm so glad it was so easy and convenient; I highly recommend it! Installation was also easy, and while we were driving into the city, we used the link to register our passport and gain access to our number!★

Used this one all the time when i go to south korea. If you’re looking for the service for uploading in the crowded area, especially my fellow fan girls out there uploading in the middle of the concert. This is recommended.★
