Welcome to the community,
It sounds like your SIMs are still waiting for activation. Have you tried to put your Optus SIM back in? You should be able to keep using your Optus SIMs until your TPG services are activated.
Could you please send me a PM (private message) with your Full Name, CID (customer identication number) and your mobile phone numbers you are porting, so I can take a look at your services?
