About eSIM square

eSIM Service Specialized for International Travelers

eSIM square is an eSIM sales service operated by Telecom Square Co., Ltd., specifically designed for international travelers. The service eliminates the need for physical SIM card replacement and allows users to purchase and use communication plans online. The service is particularly designed with clarity and convenience in mind to meet the needs of eSIM beginners and international travelers. Compared to traditional overseas communication methods, it eliminates the risk of loss or damage while reducing luggage, earning support from many travelers.

Simple 2-Step Setup Process

The greatest appeal of eSIM square lies in its ease of setup. The usage procedure consists of only two steps: “plan selection and purchase” and “installation on device.” Setup is completed simply by scanning the QR code sent after purchase, allowing even those without technical knowledge to use it with confidence. By eliminating complex setup procedures and technical jargon, the intuitive operation allows anyone to start using it without confusion, earning high praise from beginner users.

Comprehensive Plan Lineup and Coverage Area

Another strength of the service is its coverage of over 200 countries and regions with more than 300 types of plans available. In addition to single-country plans, it offers comprehensive regional plans such as “Asia Pass,” “Europe Pass,” and “Global Pass” that are convenient for travelers visiting multiple countries. The ability to select plans in detail according to travel duration and purpose helps alleviate concerns about “whether data capacity will be sufficient.” The pricing is also relatively reasonable, gaining attention as a cost-effective communication method.

Worry-Free Data Top-up Feature During Travel

With typical eSIM services, adding data capacity requires going through the entire purchase and setup process from scratch. However, eSIM square allows easy recharging from the My eSIM page. With minimal reconfiguration hassle, users can extend data capacity or usage period with one click even while traveling. Current data usage and expiration dates can be checked in real-time, enabling planned data management.

Comprehensive Support System and App Compatibility

eSIM square has established a 24/7 support system. It responds to inquiries via email and chat, providing an environment where even eSIM beginners can use the service with confidence. Additionally, dedicated apps for iOS and Android are available, enabling smooth purchasing, installation, and management within the app. The app features a simple and intuitive design that eliminates complex operations, allowing first-time users to use it without stress.
