Reviews: Japan 4G/5G eSIM 1-30 days High-speed data Daily package/Data package Optional days (calendar day) QR code
Guest User2025-12-17
It work really well. I connect directly from the app no need to scan QR. Every time I travel, I’m only gonna buy eSIM on trip.com from now on. On some occasion it can be a little slow. But it’s nothing to make a fuss about.

Reviews: Japan SoftBank 4G/5G eSIM | TikTok & ChatGPT Available | 24-Hour Billing | 1-30 Days | QR Code

The internet is okay, but the signal is weak in some areas in Kyoto. We bought 2GB per day, but it wasn't enough. Every day, it runs out at 5 PM. After it runs out, it's incredibly slow, making it almost impossible to do anything. If you're using it a lot to browse maps, use Instagram or TikTok, I recommend 5GB per day. It's better to have some extra than not enough, because it can be really difficult to search without internet.

This was my first time using an eSIM to access the internet while overseas. Previously, I found purchasing and replacing physical SIM cards a hassle, but eSIMs eliminate that hassle entirely, making them incredibly convenient. 🍋 The entire process, from application to setup, was completed online, and I was able to start using it simply by scanning a QR code. The instructions were easy to understand, and even though it was my first time using an eSIM, I was able to set it up without any trouble. 📣 The data speed was very stable in urban areas, and I was able to use social media, map apps, and watch videos without any issues. Although there were some slight drops in speed in some locations, I felt it was sufficient for everyday use. 🪾 The fee was also relatively reasonable, significantly lower than international roaming. For this price and data quality, I think it's great value for money. 🍓 The fact that no physical SIM is required and that it can be set up before departure was particularly appealing. However, I was a little concerned about the limited compatible models and weak signal in some areas. 😔 Overall, I was very satisfied with the service. This eSIM is highly recommended for those who want to easily use the internet while traveling or staying abroad for a short period of time.

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.

I had problems with my auto roaming when I was travelling in China. Contacted my service provider multiple times and couldn't resolve my issues. In the end, my cousin recommended me to use this and the experience was great. I will be recommending this to my friends too!
