@mleach - if you past the payment section, then try your sim into your phone, restart it, do you have any services?
Are you able to log into your My Account that should have been created during the activation process?
If you ported over a number, then you will need to reinsert the old SIM card back into the phone to accept the SMS text for approval.
If you did not get charged or past the payment section, you may try the activation again through a tab in incognito mode.
This link is available for activations if you are inclined to use it: Public Mobile Online Activation Assistance
