Gave friend my iPhone, still comes up as me under caller ID ?

[SPNarwhal]

Long story short, one of the retired iPhone 5 that my parents had laying around got adopted by a family friend.
Today I was told that when the person makes a phone call to anyone it still shows up under my dad's name. ?

No iCloud was on it, no sim card, and I completely reset it to factory settings. I don't know what's going on with this unless the serial number is registered to AT&T for his account or something weird like that, but I've never heard of it happening.

On top of that, who has a caller ID anymore?

That seems very odd. Caller id is associated with phone numbers, not phones. Are you talking about the outgoing caller id number, or the caller id name that pops up?

That's what I said! But it's not our sim that's in there.

I believe it's outgoing but it could be incoming. I wasn't really given clear explanation. Just was told that the phone is coming up as my dad's name. Would you know why if it was incoming?

It almost makes sense if they're talking about outgoing caller id name (CNAM). CNAM uses a data base lookup - it is not transmitted directly. Usually this is based on the phone number, but possibly AT&T is cheating a little by using the IMEI of the phone. That would explain why a different SIM comes up with the old CNAM. This is a total guess on my part, to be clear.

If it is indeed outgoing CNAM that your family friend is talking about, the easiest thing is just to change it.
If they are an AT&T customer, this can be changed directly in OLAM or the MyAT&T app, by following the directions here:

If it's a different carrier, they can call CS and ask for a change of CNAM. (They can call AT&T CS, too, if they're not technically inclined.) The advantage of doing it yourself online, of course, is no misspelling. Another advantage - you can set the outgoing CNAM to anything you want (though there is probably an obscenity check.) CNAM for one of my wife's friends comes up as "Wonder Woman."
