I'm sorry to hear that you lost your phone and your old Fizz number. It can be frustrating not being able to keep your old phone number, but you can try a few things to activate your new SIM card with your old number.
Ensure you have blocked your old SIM card and reported your lost phone to Fizz. It will prevent anyone from using your old number without your permission.
In the meantime, consider using a UK temp number service. These services provide you with a temporary phone number that you can use to receive calls and texts until you can activate your old number on your new SIM card.
