Can I still use my current email address?

If you are using a free email service such as Gmail, you can continue to use it by logging in or setting up a new device.

Please note that if you are using an email address (domain) issued by some telecommunications companies, you will not be able to use it.

There are some services that allow you to continue using carrier mail even after canceling your carrier. Please refer here for details.

J:COM MOBILE does not issue email addresses, so we recommend that you switch to a free email such as G-mail in advance.
