Step 1: Getting Started
Once you have received your Voice+Data SIM, your Voice+Data 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
Enter your SIM card serial number (if you have purchased a physical Voice+Data SIM), your eSIM Access Code and EID (if you have purchased a Voice+Data eSIM) or the IMEI (if you have purchased a WiFi device).
Physical SIM:

The SIM serial number will be written directly on the SIM card and also on the paperwork you received with the SIM card.
eSIM:
Click here for additional instructions
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.
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).
*For our eSIM products, your handset must be an actual eSIM compatible device with built-in eSIM functionality. Our eSIMs are not compatible with products such as “esim.me” that allow you to install eSIMs on devices that were not originally eSIM compatible.
WiFi Device:

The “IMEI” can be found on the label on the back of the WiFi device.
Step 3: Transferring a Phone Number?
If you already have a Japanese phone number from another service provider and you would like to transfer it to a Mobal SIM / eSIM (you can ignore this step if you have purchased a WiFi device), 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.
Step 4: Choose an Activation Date / Plan
You can then follow the prompts to choose your required activation date and plan.

Step 5: Payment
Long Term Plans (all products)
Click here for more information
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.
Short Term Plans (SIMs / eSIMs)
Click here for more information
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 Fees (SIMs / eSIMs)
Click here for more information
The usage reports for your outbound calls / outbound texts are passed on to us with a delay (of approximately 1-2 months) and so you will be charged for your usage with a delay.
Step 6: Confirmation
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+Data 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)
