Utilizzando un codice, utilizzando Google Voice
"This wikiHow teaches you how to prevent someone whom you're calling from seeing your phone number. You can do this on virtually any phone using a code prefix before dialing the other person's number. If you just want to call using a different number than your own, consider using Google Voice instead of blocking your number.
