About the new account creation authentication system (after April 2022)

We wanted to focus on improving the safety and security of our service, and this can be improved by verifying the identity of our users. In order to do that, we now require mobile phone number verification of new accounts.

If you are a user who registered before April 26, 2022 and need help with the mobile phone authentication, please contact the help desk (support@ezsms.biz)

EZSMS aims to improve security while simplifying the authentication process by introducing an external authentication service.

For users who want to create a new account after April 26, 2022, please complete the authenticatication for the following:

- E-mail address

Please register again.

By default we have set the phone numbers to numbers in Japan.
