App My050
The lowest calling rates in the market

App for VoIP calls to regular phone numbers in Japan and worldwide

  • Never miss a call, even when you have no internet connection! Have the calls to your 050 number forwarded to a mobile or fixed phone in Japan or anywhere in the world.
  • Make calls from your My 050 app at a reasonable domestic rate, even while traveling abroad. Also, when someone in Japan calls you, they just dial your 050 number without any international prefix or country code and pay the domestic rate.
  • Make and receive calls by obtaining a 050 number, even if you are using a data-only SIM.
  • Register for a 050 number in addition to your current mobile line and separate your work calls from your private calls received on the same smartphone.
  • Before using, top up your My 050 account at any time online or at a convenience store.

※ When calling a 0120/0800 Free Dial number, your 050 number is not going to be displayed due to a technical specification. Therefore, the call cannot be connected if a called party is set to reject anonymous numbers.
※※ The My 050 Number service does not support SMS.
※※※ We do not accept applications that are sent from the same email address (with the exception of minors) or applications that use disposable domain email addresses.

application and maintenance fees!

Only for users with a My 050 number

Fees (non-refundable, tax included):
Application fee: ¥550.
Maintenance fee: ¥550 every six months.

After we validate your application, we will issue you a My 050 number. You will receive the contract details by email. We will also give you 5 free minutes and 8 days to test incoming and outgoing calls with your terminal and internet environment.

The application fee together with the first maintenance fee will be deducted from the customer's Brastel account balance on the 9th day after the application is validated and a 050 number is obtained. Each subsequent maintenance fee will be deducted from the customer's Brastel account balance at the end of every billing period of 6 months.

Important! If there is no sufficient balance in your account, your 050 number will be temporarily deactivated, and you will not be able to make or receive incoming calls. Once you top up your Brastel account with enough credit to cover the maintenance fee, your account will be automatically reactivated. If your 050 number remains deactivated for six months, it will expire permanently. Once your 050 number expires, you will need to apply for a new Brastel account to get a new 050 number. However, if there is any outstanding balance associated with your previous number, no application for a new number will be accepted until this balance is cleared.
※When recharging your account by means of credit transfer after your My 050 number has been deactivated, the application and the maintenance fees cannot be automatically withdrawn, so please contact customer service to help to activate your account.
