It may take around 4 hours for your new VIVIFI SIM to be automatically activated upon SIM delivery/collection. You may contact VIVIFI at help@vivifi.me if your SIM is still not getting any signal after 4 hours.
If you are porting in your mobile number, please note that the temporary VIVIFI number will be activated first. This temporary number will become invalid once your number has been ported in successfully from the other Telco.
