Urgent | No Smarty service nor previous provider after porting

Bought a new Smarty SIM in order to port over the services/contract and number from another provider. My current provider has advised me that my service with them will terminate today once the porting completes. However, after activating the Smarty SIM via your app, the SIM appears inoperative (I've tried multiple unlocked phones) and therefore I never received your activation txt/sms. Despite the above , Smarty is proceeding with the porting I had requested at the contract start, and as a result, I will loose all connectivity within the next few hours (current and future Smarty) and I need to always have connectivity. Please resolve this a matter of urgency. Connectivity for vulnerable people applies. Thank you.
