I used this for about a year and canceled the contract last month. There is no remaining balance on the device. By separately contracting with SoftBank for a line, you can use the internet without construction, just by plugging it into a power outlet. Retail price: 71,280 yen Brand: SoftBank Model name: Air Terminal 5 Communication standard: 5G Accessories: AC adapter, LAN cable, connection guide Model number: CKB01 Thank you.
