Just visit the US Mobile website and click on "Sign in" in the top right corner. Use your registered email ID to log in. It'll be the same one that you used while creating your US Mobile account.
I forgot my password
If you don't remember your password, click on ‘Forget your password?’
Next, enter your registered US Mobile email account and click "SEND NEW PASSWORD," An email with a randomly generated password should land in your inbox within a minute or two. If it's not there, check your spam/junk folder.
Use this password to log in, and don't forget to update your password by clicking on "Settings" in the left-hand column from your dashboard. A good password should be easy for you to remember but hard for others to guess. A combination of letters and numbers is usually a good way to go. We firmly recommend NOT using the same password across multiple websites/services.
If you are still having issues signing in, please refer to this guide. For further assistance, feel free to get in touch with support via chat, call (1-878-205-0088), or email help@usmobile.com.
