By using blackberry phone caller id can block..that means my phone number cant displyed others mobile who am calling..only shows PRIVATE NUMBER CALLING ,.. like it possible on android mobile or not
That's carrier-centric, not phone-centric. Most carriers use *67 to block an individual call - just dial *671234567890 (or whatever the phone number you're calling is). Most carriers also can permanently block your caller ID - then *67 allows the caller to see your ID for one call.
