T-Mobile users who have an active T-mobile cell phone plan also have an e-mail address that is accessible online. This allows people to send e-mails to your phone and also to your T-mobile online account. By default the e-mail address is your 10 digit cell phone number followed by @tmobile.net.
Open your web browser on your computer and visit the T-Mobile main website. The link is available in the Resources section of this article.
Enter your cell phone number and your T-Mobile online account password in the log-in box located at the upper right of the screen and click "Log In."
Click on the "Connect and Share" tab in the upper section of the main account section page. Under "Connect and Share" select "E-mail" or "Configure E-Mail."
Click on the e-mail account that is your 10-digit T-mobile cell phone number followed by @tmobile.net. You will be able to access any e-mails sent to this e-mail address.
