Activation Requests

Step 1: Getting Started

Once you have received your Voice+Data SIM / eSIM Access Code, your Voice Lite SIM / eSIM Access Code or your WiFi Device……

You can submit an activation request directly from your Mobal online account (MyAccount): www.mobal.com/myaccount


*Login details will be sent to you via email shortly after placing your order or you can request a password reset link from the login screen

Once you have logged in to your account, simply visit the Services section and click on the Activate button found next to the relevant product.


Step 2: Enter Product Details

If you have purchased a Voice+Data SIM Card or a Voice Lite SIM Card, you will be asked to enter the SIM card serial number.

If you have purchased a Voice+Data eSIM, you will be asked for your eSIM Access Code and EID but if you have purchased a Voice Lite eSIM, you will only be asked for the eSIM Access Code.

If you have purchased a WiFi Device, you will only be required to enter the IMEI number of the device.

The SIM serial number will be written directly on the SIM card and also on the paperwork you received with the SIM card.

You will receive the “eSIM Access Code” in the mail or from your chosen collection point (it’s an 8-character code containing both letters and numbers).

The “EID” is a unique 32-digit number that identifies the eSIM chip on the device you wish to use. The EID will only be required if you have purchased a Voice+Data eSIM.

On most handsets, you can locate the EID by dialing: *#06#

Alternatively, you may be able to locate the EID by going to Settings > General > About > EID (on most iPhone handsets) or by going to Settings > About Phone > Status Information > EID (on most Android handsets).

The “IMEI” can be found on the label on the back of the WiFi device.


If you already have a Japanese phone number from another service provider and you would like to transfer it to a Mobal SIM / eSIM, please also select the “Yes, I want to keep my existing phone number” option.

You can then enter your current Japanese phone number, the MNP reservation code / MNP code expiry date (which you will be required to retrieve from your current service provider), your name and your date of birth.

If you do not have a phone number that you wish to transfer however, simply select the “No, I want to receive a new phone number” option instead.


You can then follow the prompts to choose your required activation date and plan.

Choose a WiFi plan that includes a 100GB, 200GB or 300GB high speed data allowance each calendar month. Your plan will remain active until you submit a cancellation request directly from your Mobal online account (MyAccount).


Step 5: Payment

Pay a partial pro-rated amount covering your initial billing period (for service between the activation date and the end of the current month). All plan fees after the initial fee will be billed in full on the 1st of each month.

Pay upfront for the selected 30, 60 or 90 day plan during the activation process.

Your plan will then auto-disconnect at the end of the short term plan you have selected and so you will not incur any additional plan fees (unless you manually extend the plan or switch to a long term plan).

Usage reports are usually passed on to us with a delay (of approximately 1-2 months) and so you may find that usage fees are processed at a later date.


After you have completed steps 1-5, you can then submit your activation request for processing.

Once your Mobal plan has been activated for the requested date, you will receive a confirmation email.

If you have activated a Voice capable SIM/eSIM, the confirmation email will also contain the Mobal phone number that you have been assigned.

* A phone number will only be assigned to your SIM/eSIM at the point of activation (and so we are unable to provide the phone number in advance)
