*67 will cause various messages to appear depending on the phone and carrier the call is going to you may get unknown caller, number unavailable, private If the caller id is not blocked then the calling number is displayed on a cell phone and the name appears if in the phone contacts. Land line caller id will normally display the name of the caller or wireless caller depending on what is in there data base for the callers name. Do not know of a way to have only private caller show up with any reliability Some one else may have a way
I remember that conversation too. It was either through a "rooted" phone or a number that was blocked. I am such an idiot with this stuff, it's frustrating. Common sense tells me that if it came up as "N" the receiving caller couldn't call it back like you could an identified number- i.e., by touching the number to return the call??? Does that make sense?
Here's how Caller ID works. Sprint, like all carriers, only sends your phone number to the other party. If you add Caller ID restriction on your account, they do not.
The name that shows up on the recipient's end is dependent on the receiving party's phone or carrier. When Sprint updates your Caller ID name, it just sends that information along with your number to all of the landline carriers. They then update a database with that information. Whenever your name shows up, their switches access the database and send the name along with the number. If the number is blocked, the receiving carrier will send the recipient a set "name" such as "Unknown", "Private", or "Restricted".
Unlike landline companies, cell phone companies only pass the number through. They do not maintain a names database. It is up to the recipient of the call to add the number to their contacts so that a name shows up on the phone along with the number on future calls.
