I have an 821 error code and was directed to submit a ticket. When I go through the process of submitting a ticket it asks me to verify my identity with public mobile number and account number etc all info I dont have yet
Do not try to activate again! Check your payment card to see if your plan amount has been charged.
Try SIM in some other phone. That will determine if it is your phone hardware issue.
Usually 821 is missing/incorrect porting information. Your SIM card will need provisioning to your incomplete account activation. Send a private message to customer support with "incomplete activation" in the subject line and explain in detail your issue. Once the CSA sets it up correctly you will be able to finish your self serve account set up.
@SJEcrawley - if this is related to porting over a phone number from another provider and you experienced issues during the activation, and you got back the payment section and were charged, then you can also use this direct link for porting issues to submit a ticket with Public Mobile representatives (CSA) for help; click this link: to request the transfer of your number over to Public Mobile.
