Can I make phone calls on an Apple hacked machine?

Check to see if it is locked. If not, you can make a call.

For hacking machines, there are two types of hacking modes:

One is the more common card-based hacking method, which uses the leaked ICCID to deceive the Apple server through the card sticker. It issues a lock-free certificate, and then you can remove the card sticker and use it as a lock-free machine.

The second method is the genuine black solution which is quite popular now, that is, the first method of unlocking can be achieved without card stickers.

However, both methods may be discovered by Apple servers. When discovered, your unlocked phone will be re-locked, and you will no longer be able to use SIM cards from non-designated operators, that is, you will not be able to make calls or send text messages. This is commonly known as anti-locking.
