Cloud SIM technology is a technology which enables to manage multiple SIM cards on a server. Users can use multiple SIM cards on a single Wi-Fi router. With our Wi-Fi using cloud SIM technology, you can switch SIMs on the server, which means that you will have a wide coverage of network from major Japanese telecom companies, allowing you to communicate in a wide range of areas.

As cloud SIM technology manages multiple SIM cards on a server, it is easy to switch SIM cards. If one SIM card reaches the data usage limit and drops the speed, it can be switched to a new SIM card, enabling large volume & high-speed communications. * If you have used a large amount of data in a short period of time, reboot your WIFI device and you will be connected to the optimal SIM card.

A cloud SIM holds SIM information from around the world stored on a cloud server, and when needed, the SIM information can be downloaded to a cloud SIM-compatible Wi-Fi device. With conventional SIM cards, each smartphone or tablet contains one type of SIM card. Depending on the information on this SIM, users could make calls, access the internet, and use other services. However, cloud SIM technology stores and operates SIM card information from multiple telecom companies on a cloud server. With this technology, the optimal SIM information for the Cloud Wi-Fi, will be automatically selected depending on the location and environment. The Cloud Wi-Fi we offer, introduced Cloud SIM technology to provide a wide range of high-quality communication using the networks of three of Japan's major telecom companies.

Conventional mobile Wi-Fi carries one SIM card in one Wi-Fi router, whereas Cloud Wi-Fi manages multiple SIM cards on a cloud server. It downloads the information of the most suitable SIM card depending on the location to the Cloud Wi-Fi for optimal communication and to provide a stable communication environment.
