Y!mobile uses the same network as SoftBank, so you can enjoy stable, high-speed communications over a wide area.
Supports Massive MIMO, 256QAM, and 4x4 MIMO
It enables smooth mobile communications even in crowded places such as stations and downtown areas, where communication speeds tend to be slow.
This technology uses four antennas on both the handset and the base station, which increases the amount of data that can be transmitted at one time and the speed compared to conventional methods.
A modulation method used in wireless communications, it is a technology that increases the amount of data that can be carried at one time by increasing information density.
Carrier aggregation is a technology that bundles radio waves of multiple frequency bands together to send and receive data over a single communication line.
The maximum download speed will vary depending on the area and device you use.
For details, please select the applicable model from the product list and check.
Because this is a best-effort method, communication speeds may be slowed down or communication may be impossible depending on line congestion and the communication environment.
The areas where maximum download speeds are available for each model listed in ① to ⑤ below are as follows:
