Started multi-carrier SIM "FIELDCONNECT eSIM" service that can be used by automatic switching between two major mobile carriers
Data communication eSIM that can seamlessly use the service areas of both NTTdocomo (5G/4G/3G) and KDDI (au4G) with smartphones, tablets, IoT devices, etc. is born!
FIELDCONNECT eSIM is a service that allows mobile data communication by automatically selecting a carrier with better communication conditions according to the location of the terminal with just one eSIM, even if the carrier to be used is not selected in advance.
It can be conveniently used for backup lines in the event of a disaster or communication failure, as a countermeasure for distress during mountain climbing, for use in outdoor activities, and for work in mountainous areas. It can be used for various purposes such as easy understanding of the cost of equipment and flexible equipment operation due to the increase in options for installation locations.

What is FIELDCONNECT eSIM?
FIELDCONNECT eSIM is a multi-carrier SIM dedicated to data communication that allows you to use both NTTdocomo (1G/5G/4G) and KDDI (au3G) radio waves (service areas) with just one eSIM contract. We are collaborating with Transatel, a French company that is a member of the NTT Group and provides global cellular connectivity solutions and IoT connectivity around the world.
Features of FIELDCONNECT eSIM
FIELDCONNECT eSIM is not multi-carrier compatible in the sense that it is a provider that combines multiple SIMs or provides each SIM of multiple carriers, but it is characterized by being able to use two carriers with just one eSIM contract.
Benefits of using FIELDCONNECT eSIM
Depending on where the smartphone, tablet, or IoT device is used, the carrier (NTT docomo or KDDI) with better communication is automatically selected at the time of communication and mobile data communication is possible, so there is no need to manually switch carriers in advance. In addition, the advantage is that you do not need to be aware of which carrier's service area you are using the terminal.
Use scene
・As a backup line in preparation for disasters and communication failures
Even in the event of a disaster or a communication failure with a mobile carrier, you can use another carrier, so you can be prepared for peace of mind as a backup in case of emergency.There are no restrictions on which telecommunication companies can be used together, so if you can use it, you can add FIELDCONNECT eSIM to the plan of your current main mobile phone company (including cheap SIM companies) as it is. increase.
・For the disaster measures of the mountain climbing
If you are in an accident while climbing or hiking, depending on the situation, you may need to notify your family, acquaintances, or workplace of the emergency. It makes a big difference whether
Since FIELDCONNECT eSIM is only for data communication, it does not support phone calls (including emergency calls such as 110 and 119), but voice calls and messages can be used with communication apps such as FaceTime, LINE, WhatsApp, and Facebook Messenger. can.In such a case, being able to use a service area that combines NTT docomo and KDDI (au) not only creates a great sense of security, but also leads to quick rescue.In addition, by reducing the number of out-of-range areas, it will be easier to use when combined with various climbing apps and mountaineer monitoring services such as FIELDCONNECT.
・For outdoor activities and work in mountainous areas
Even if it is necessary to communicate during outdoor activities such as camping and winter sports, the availability of two communication carriers reduces the out-of-service area and makes it easier to contact.It is also recommended to use a multi-carrier SIM such as FIELDCONNECT eSIM on a daily basis in areas where radio waves are basically poor, such as when working in mountainous areas.
・Easy cost understanding in IoT cellular communication
FIELDCONNECT eSIM demonstrates its power not only for use with smartphones and tablets, but also for use with IoT devices.The flat-rate system makes it easy to understand the cost, so it is safe even for IoT solutions with a large number of terminals.
・Expansion of options for operating IoT devices in mountainous areas
Even in areas where cellular radio waves are unstable, such as in mountainous or mountainous areas, the use of radio waves from two major domestic telecommunications carriers not only stabilizes communications, but also expands the options for installing IoT devices.
Reasonable and secure monthly fee system
Most multi-carrier SIM services in Japan are pay-as-you-go services that charge only for the amount you use. It's safe.As of July 2023, 7, this is the lowest usage fee in Japan for a multi-carrier SIM for data communication.
