For the average traveler, a hotel's star rating is a crucial guide for choosing accommodations. 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.★

Reviews: South Korea | 5G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code
Guest User2025-12-12
The card was issued quickly and I connected it in Japan before flying.
When I arrived and used data roaming on the plane, it connected immediately.
The connection was good and I was able to use Maps, Instagram, TikTok, etc. without any problems.
I would like to use it again if I have the opportunity.★

I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.★

Reviews: [South Korea] LG U+ Combo Card | Unlimited Data 4G/5G SIM Card + Tmoney Transportation Card | 1–60 Days | Pick-up at Incheon, Gimpo, Gimhae Airports
Guest User2025-11-25
I didn't use the call answering function, and I'm not sure if it's activated or not, but the internet speed is definitely fantastic. I'll definitely buy this again next time I go. The card pickup and installation at the airport are extremely convenient. Highly recommended!
It's definitely worth buying; you get what you pay for. The counter is easy to find, and the staff's service is superb. Even though we speak different languages, they made sure you understood. The card is also great for taking the subway and buses; a quick swipe is super convenient and saves you from carrying multiple cards. I can use this again next time.★

I previously used the free eSIM offered by my Diamond membership; the speed was acceptable, installation was easy, and I received it within minutes of redeeming it. This time, I tried ordering it again, and the price was very cheap, and I received the QR code quickly. I hope my journey goes smoothly. If it works well, I will definitely repurchase! ESIM is a popular trend now, and the key is fast delivery and immediate installation.
