For more information about the Japan Travel SIM:

In the communication package you get two products: the Japan Travel SIM and the Brastel Card.
With the SIM card you get the data service to use your smartphone or tablet, and the Brastel Card allows you to place calls by using the My 050 app.
As an option you can also get a phone number in Japan allowing you to receive incoming calls, and you may even continue using it after returning to your home country, with other SIM cards or Wi-Fi.
In addition, you can add extra data on the Japan Travel SIM card with credits from the Brastel Card in case you run out of the initial 6GB or 15GB of data.

Setup your phone

After activating the SIM card, please follow these instructions.

On the App Store/ Play Store, search for My 050 and install it.

Scratch off your Brastel Card.
On the setup screen enter your card’s user ID and password, and tap on Save.
You may disable the app’s GSM button to place calls easier.
Go to Settings > Preferences > Controls, disable Show GSM button and press Done.

Top up the Brastel Card

Recharge the SIM card

You can recharge (top up) the SIM with more data without having to purchase a new SIM card.
First, recharge the Brastel Card enclosed in the package, and then recharge the SIM with credits from the Brastel Card.

To recharge the Brastel Card online, in the My 050 app tap the globe icon (My Account) Payments, or sign in to My Account (online payments) on your PC; or use the enclosed coupons to pay at convenience stores.

To recharge the SIM, in the My 050 app tap the globe icon (My Account) SIM RECHARGE, or sign in to My Account (SIM recharge) on your PC.

To sign in to My Account you will need the access code (user ID and PIN) printed on the back of your Brastel Card.

Available recharge plans

The SIM will initially expire 30 days from the usage start date. Each data recharge will extend the SIM's validity until the end of the third month after the recharge. Upon the first recharge, the initial data provided will be extended to the end of the second month after the start of use. Additionally, any remaining data from your previous top-up (excluding the initial SIM card data) will be extended upon a subsequent recharge, remaining valid until the end of the fifth month after adding this new data. The SIM becomes invalid if no additional recharge is made before the final expiration date. Click here to see an example.

SIM validity extension example

6 GB (usage start)ExpirationExpiration
Jan 01Jan 30Mar 31
2 GB (recharge)ExpirationExpiration
Jan 20Apr 30Jun 30
5 GB (recharge)Expiration
Apr 10Jul 31

The example above illustrates how the validity of the SIM is extended when the SIM is recharged. For the sake of this example, we will assume no data is consumed.

  • A 6 GB SIM starts being used from January 1. The 6 GB will at first expire on January 30.
  • A recharge of 2 GB is made on January 20. The added 2 GB will expire on April 30. The expiration date for the initially granted 6 GB is extended to March 31.
  • If a recharge of 5 GB is made on April 10, the added 5 GB will expire on July 31. The expiration date of the 2 GB from the first recharge will be pushed back only until June 30 (the fifth month after January, the month when they were added to the SIM).
  • If no further recharges are made until July 31, the SIM becomes invalid after this date.

    The remaining data can be checked by accessing https://tr.iijmio.jp/login/ or right after recharging the SIM card via My Account.

    You can add extra data using the Brastel Card (enclosed in the package).
    Please see the Recharge the SIM card section above.
  3. Why can’t I recharge the SIM card?
