Fast urban 5G on SoftBank — made for heavy data users

uSIM on the SoftBank network

A SoftBank-network plan sold and supported by KEICALL. SoftBank's network is known for fast 5G in urban areas, making it great for heavy data use. A Japanese phone number (calls & SMS) is included — banks, clinics, deliveries and job applications, all with one SIM.

Plans (monthly)
