nazywam sie vs na imie mi - the difference

Hi there,
What is the difference between:

nazywan sie
and
na imie mi

?
Many thanks
Kelvin

Nazywam się (not "nazywan") :-)
You give you whole name like James Bond

Na imię mi (you can also say "mam na imię")
You give your first name only like James

Its not true that after nazywam się you give your whole name... you can as well give your first name only (most people use nazywam się)

Na imię mi (is rarely used) and yes after this you give your first name only

Merged: Nazywam się vs Jestem

On several occasions I have heard/read the word "Jestem" used when someone is saying their name instead of the usual Nazywam się / Mam na imię.

When is it ok to do this? If it's a nickname etc... or a positive affirmation/correction of your name?

nazywam się "I'm called ...." (my name is but usually first and last name are given)

mam ni imię "My first name is ....." imię is 'first name, personal name"

Jestem "I'm ......." in the phone context, it's a little like saying "This is (name)"

"jestem ..." is more unofficial - you say it when you shakehands with someone on barbecue.

Ok, thanks guys. I'd only heard it on movies/cartoons featuring superheroes so I wasn't sure of the more general usage.

Jestem wspanialy. Jestem James Bond ;)

Interesting example, in films he normally says "The name's Bond, James Bond"
I was wondering whether sometimes the use of "Jestem" was the subtitlers being lazy/economical with words.

Czy pan jest Polakiem? - Tak, jestem. (or: Nie, jestem Niemcem.) = Are you Polish? - Yes, I am (No, I'm German). In English, chances are we'd be as likely to ask "Are you from Poland?", rather than "Are you Polish?", much the same in the response "I'm from Poland."/"I'm from Germany." etc. It's more of a cultural point, I suppose.

Nazywam się błąd. Wielbłąd.
Would jestem look better? Who is this camel anyway? Maybe it's not even a camel.
