2.3 Change your email
According to connection mode, email address may not be an essential data. However, it is always better to have it on your SMS user profile. Since connection mode may be changed later to mode 0 or 3, those SMS users without email address will not be able to login to the SMS server anymore. To input or change your email address, click on 'Email' on main menu, screen like figure 2.3.1 will be displayed, put your email address on the email input field, and press the 'Save' button to save it.
