Enter your mobile number in the field, and choose to send your password reset link by email.
You will need to remember and have access to the email address with which you registered the SIM to.
You can also text NAME and PASS to 43430 (in two separate messages) for free. Wait a few minutes and the replies will contain:
- Your username
- Your registered email address
- A link to reset your password
The reply will be something like “The email address you used when you joined is …………………………... If you've forgotten your password click here to reset”
Once you are logged into your account, I recommend you simply setup your goodybag to automatically recur each month like a direct debit, so you don't have to worry.
