How to sign the certificate of 5230GBA simulator?
I'm sorry to tell you that Saipan can't get a visa and a certificate. The direct signing tool should not be able to sign the simulator. If you must play the simulator, you'll have to ask someone else to teach you how to crack the phone. After cracking the phone, all software does not need a visa. You must find someone who can crack the phone. Don't try indiscriminately. If you don't do it, you will become a brick machine.
