Public Mobile is completely online, they have nothing resembling a bill or invoice that I can attach to a port request. There is one page that shows some account information, another that has estimated billing for the next cycle (but no account info).
What do I need to provide a signed copy of to initiate a port of the number?
Hello @sequalsoft,
I would suggest submitting a ticket to the support team. They will be able to answer you very quickly. (Then you can come back with the answer! 
)
Kind regards,
Alexandre
Probably resolved already (contacting an agent solves most problems), but you can see your acct # on PM website (screen capture here 05.05.2024-14.51.32 )
You can also download a payment history (not exactly an invoice), here’s what the link looks like 05.05.2024-14.56.31 and this is what the payment history looks like 05.05.2024-14.54.08
I did open a ticket and was told I could include screen shots with my port request.
I haven’t got around to it yet (I missed the rollover date).
