Simply log on to www.tescomobile.ie and click the My Tesco Mobile tab.
This will bring you to the login page. As a new customer, you should click on "Register now".
You'll be asked for your mobile number, and some details such as name, address and mother's maiden name. When you submit these details, we will text a secure password to your phone so you can complete registration and log in.
We suggest you change this password to something easy for you to remember once you have completed registration.
Changing Your Password
Once logged in, go to the 'Details' tab on the left hand menu. From here, choose the option to Change Password.
Just enter your current password, your new password, and confirm your new password. Click on Change Password at the bottom to complete.
If you have forgotten or need to reset your password, go to the My Tesco Mobile tab. This will bring you to the login screen, where you click on the “forgot your password” link.
You will be asked for your mobile number and your mother’s maiden name (in the case sensitive format you entered on registration).
You will then be sent a text with a new password.
