Not able to do the phone number authentication
When using an iPhone, you might not be able to receive SMS by default.
In that case, please follow the procedure below.
Open “Settings” on iPhone and then select “Messages” and turn off the “Filter unknown sender” setting.
Please try sending the message after changing the above setting to off.
In addition, even devices other than iPhone may not be set to receive SMS from overseas by default.
So please make sure to change the settings.
If you are not able to complete the authentication, you may try to authenticate by sending an SMS as stated in the URL below.
If you are not able to complete the authentication even using the above instructions, please contact us from the inquiry form.
