I tried to transfer to a new network and needed my account number and PIN. I called customer support, and they said to get my account number I needed to verify by giving them two numbers I call often. This is a very uncommon and strange verification process. I gave them the only two numbers I ever call and they said they were unable to verify. This is a scam company that tries to lock its customers and does not let them transfer out of their network with their original phone number. Do not sign up with them.
