About My IIJmio
“My IIJmio” is an official application of the IIJmio Mobile Service.
You can check the remaining data volume and details of the subscription, and turn on/off high-speed communication.
■IIJmio Mobile Service
https://www.iijmio.jp/ (Japanese language)
■Main features of My IIJmio
1. Checking the remaining data volume for the month and switching between high-speed and low-speed communication
You can check the remaining data volume available for the month in real time.
If you have a data sharing line, total amount of data volume including shared lines is displayed on the app.
Data capacity on current contract is displayed. (The one of discharged contract is not shown.)
You can also turn on and off high-speed data communication.
2. Checking data usage
With a graph, you can easily check daily and monthly data usage for the past five months.
3. Checking details of subscription
You can check the price plan, service usage status, and start day of use.
4. Switching the display individually
If you (subscribers) have some lines which are shared by different users on the same contract, each user can display the usage status by your operation.
For example, if you would like your child to use the app, by selecting the user at the first option,
it will not display any information on the subscription, such as a change of service or purchase of data capacity. So, you do not need to worry about an operating error.
