The guides below contain additional information on the Wi-Fi plans that we offer and instructions on how to submit a plan change request / how to submit a termination request from your online account: MyAccount
Please be advised that the options available to you will vary depending on the plan that is currently selected.
To proceed, please click on the relevant button below and you will be redirected to the correct section:

Plan Changes
By default, your device will be placed on our standard 100GB plan at a rate of ¥4,980 per month but we also offer a 130GB plan and a 150GB plan (if you find that the 100GB allowance is not enough for your requirements).
To submit a plan change request, you will firstly be required to login to your Mobal online account: MyAccount
Once you have logged in to your account, please click on the “Services” tab located at the top of the screen and then click on the “More Information” button next to your device as shown in the image below.
Plan Upgrades
If you would like to upgrade to a plan with a larger data allowance, please click on the “Upgrade Plan” button found to the right in the “Plan” section (on the desktop version of the site) or found at the bottom of the “Plan” section (on mobile devices) as shown below.
You can then select the plan that you would like to upgrade to and the date you would like the upgrade to complete.
Please be advised that your plan cannot be changed part way through a month and so the earliest plan change date you will be able to select is the 1st of the next month.
Once you have made your selection, please click on the “Submit” button.
Plan Downgrades
If you previously upgraded your plan but you would now like to downgrade to a plan with a lower data allowance, please click on the “Downgrade Plan” button found to the left in the “Plan” section (on the desktop version of our site) or found at the top of the “Plan” section (on mobile devices).
You can then select the plan that you would like to downgrade to and the date you would like the downgrade to complete.
Please be advised that your plan cannot be changed part way through a month and so the earliest plan change date you will be able to select is the 1st of the next month.
Once you have made your selection, please click on the “Submit” button as shown in the image below.
However, you must ensure that you submit your downgrade request at least 48 hours prior to the 1st of the month (so that your request can be processed in time).

Termination Requests
Once you have finished using your ‘Japan Unlimited’ SIM card and you are ready to terminate your service, please login to your Mobal online account to submit a termination request.
For additional instructions on how to do this, please click on the button below:
If you submit a termination request however, please be advised that your SIM card will be permanently disconnected and so you will not be able to use the SIM card again.
To use the same service again in the future, you would be required to purchase a replacement SIM card which will be assigned a new phone number.
