Using a code, using 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.
