Get MNP reservation number from current carrier

If you are using MNP to transfer your current phone number.

You need to obtain an 'MNP reservation number' from your current carrier.
(LIBMO does not support MNP One-Stop as of March 2026)

This time, I'm transferring from Rakuten Mobile, and I've explained how to get an MNP reservation number from Rakuten Mobile here.

If you are transferring from another carrier, please research separately and prepare your 'MNP reservation number' and its 'expiration date'.

Temporary Application

here and proceed with the temporary application.

For temporary application only, either PC or smartphone should be fine.

Tap 'Apply for LIBMO'

You can also apply for LIBMO's various campaigns from this button. Please rest assured.

Select as you prefer.
This time, I selected 'Apply for Voice SIM', 'Nattoku Plan (8GB)', and 'Do not purchase a smartphone', then tapped 'Proceed to application procedure'.
Also, applicable campaigns were displayed on this screen. You can apply them by proceeding as is.

It's long, so I've shortened it.

Required items for application are displayed.
Agree and 'Proceed to application procedure'

Select SIM type.
This time, I selected 'eSIM'. For eSIM, enter the smartphone's 'EID'.

Select SIM type.
Select 'Voice SIM'.
On the next screen, this time I selected 'Keep current phone number' and 'Next'

Enter the 'MNP reservation number', 'expiration date', and 'phone number' obtained from your current carrier, then 'Next'

Select a plan.
This time, I selected 'Nattoku Plan 8GB' and 'Next'

Select call and other options as you prefer and 'Proceed to subscriber information registration'

It's long, so I've shortened it.

Enter subscriber information.

It's long, so I've shortened it.

Confirm the details and 'Proceed to payment information registration' at the bottom.

Enter payment information.
This time, I selected credit card and 'Register credit card information'

Enter card information and 'Agree and proceed'.
On the next screen, confirm the details and tap 'Apply'

Agree to the terms and 'Confirm application details'.
On the next screen, it showed 'Temporary application accepted.'.

Next, let's proceed to the full application.

LIBMO is here

Full Application & Identity Verification

Check your email and open the email titled '[LIBMO] Temporary Application Notification'.

I think it's smoother to complete the full application using a smartphone that can read My Number Cards or a smartphone with a camera.

Open the 'URL for full application' provided in the email.

Set your LIBMO My Page password, email delivery settings, and contract document confirmation method as you prefer, then 'Proceed to identity verification document registration'

Select identity verification document registration method.

1. Method 1: Enter My Number Card password and read IC chip
2. Method 2: Read IC chip and take a photo of your face

There seem to be two ways. This time, I'll go with method 1.

You will be asked to install an app called 'TRUSTDOCK', so let's install it.
(You can delete it after everything is done)

After installing the app, tapping 'Open TRUSTDOCK app' from this screen again started the identity verification.

I couldn't take screenshots of the TRUSTDOCK app because it's prohibited, but it was just a matter of following the instructions for these two steps.

1. Enter My Number Card password (the 6-16 character alphanumeric password, not the 4-digit PIN)
2. Read My Number Card

Once identity verification was complete, it automatically transitioned to the LIBMO page and showed 'Your identity verification documents have been submitted.'.

A confirmation email also arrived.

I wondered, 'When can I start using eSIM?'

The official website stated, 'After 4 PM on the day following identity verification, emails regarding eSIM activation procedures will be sent sequentially'.(As of March 2026)

LIBMO FAQ | How long does it take to use eSIM after the procedure?

So, let's patiently wait until 4 PM the next day. (If this changes in the future, please let me know in the comments)

While waiting, to receive TLC points from LIBMO campaigns, you need to register for a 'TLC account', so let's register.

The email also contains the URL for the TLC account.

TLC Account Registration

To receive TLC points from LIBMO campaigns, you need to register for 'TLC Member Service'.

Also, for every 200 yen spent on LIBMO monthly, you earn 1 TLC point, and 1 TLC point can be used as 1 yen for monthly payments.

How to use TLC points for LIBMO payments is introduced below.

Now, let's register for a TLC account from here.

Enter your 'ID (email address)', 'Name', etc.
For 'Service in use' in the middle, select 'LIBMO' and enter your LIBMO 'User ID'.
This links your membership information, and points for campaigns will be awarded.

It's long, so I've shortened it.

Confirm the details and tap 'Proceed to phone verification'

On the next screen, call the phone number displayed.

The call will disconnect instantly, so there will be no call charges.

This seems to be the login method for TLC Member Service.

TLC account registration complete.

For some reason, 300 TLC points were awarded upon registration.

It looks like I can use them for LIBMO payments right away.

eSIM Activation

The next day!!
An email arrived exactly at 4:00 PM.

A Wi-Fi environment is required for activation, so let's proceed in a Wi-Fi environment from here.

Open the URL provided in the email.

Enter 'User ID', 'Date of Birth', and 'Transfer Phone Number' and 'Send'.
On the next screen, enter the one-time password sent to your email.

(User ID is stated in the email.)

Upon logging in, it was still 'Under review'.

After waiting a bit and checking, it became 'Waiting for activation request', so I tapped 'Activation Request'
(According to the screenshot time, around 16:18?)

It showed 'Activation request accepted.'.
I'll wait a bit longer.

eSIM Activation (Main Procedure)

From here, I'll proceed according to the steps on the official website.
Android users may find the official website more helpful.

eSIM Setup Method | Docomo-line Low-Cost SIM/Smartphone LIBMO

From here, if you are currently using a physical SIM, please remove the SIM card beforehand before proceeding.

If you are currently using eSIM, from iPhone's 'Settings > Mobile Data'

Please turn off your current line temporarily before proceeding.
You don't need to delete the eSIM yet. You will delete it later.

Well, I forgot to turn it off, but it was fine.

1-2 minutes after sending the activation request, a notification arrived on my iPhone, so I tapped it.

If you don't receive a notification, click here

The 'Activate eSIM' screen will appear, so tap 'Continue'

After 'Activating', it will show 'Done'.

In my case, I forgot to turn off eSIM beforehand, so I got a screen like this, but I just set it up temporarily.

Download Configuration Profile

You cannot communicate with this alone yet.

Now, we will download the configuration profile required for communication.

Select iOS or Android from the page below

eSIM Setup Method | Docomo-line Low-Cost SIM/Smartphone LIBMO

Tap 'Download Configuration Profile'.

I'll also put the links here

iOS: Download Configuration Profile

Android: APN Settings

For iOS, access the URL to download the configuration profile.

I'll also put the links here

iOS: https://www.libmo.jp/ios/

For Android, manual input is required, referring to the APN Settings page.

From here, it's for 'iOS' for a while. (Android users should have already completed APN manual input)

Allow the configuration profile download and download it.

Open Settings and tap 'Downloaded Profile'

Follow the on-screen instructions to install.

This completes the configuration profile installation.

As a test, turn off Wi-Fi and check if you can view websites.

If you were originally using eSIM, delete the eSIM from your previous carrier.
You can delete it from 'Settings > Mobile Data > (Previous Carrier) > Delete eSIM'.

After installing LIBMO's configuration profile, 4 shortcuts were added.
(I'd prefer if this didn't happen...)
