* Packet communication charges may apply, so subscribing to a Packet Pack is recommended.

● Light mode allows speed measurement with about 1/10 of the data usage of normal mode.
* In WiFi environments, measured values may be unstable in light mode. Please use normal mode for WiFi speed tests.
* After April 1, 2018, versions earlier than 1.6.0 cannot use light mode. Update to version 1.6.0 or later to enable it.

● Large mode measurements may use up to 1000MB of data. Please proceed only after consenting to the possibility of higher packet communication charges.
