SIM CARD PIN reset after backup from itunes?

Hello community!

I have the following problem:

my iphone was stolen on new years eve:

I blocked my number then and ordered a new one.

As soon as i got the new iphone i transferref my number.

Once transferred - i got home from work - connected the phone to my itunes

and it asked me if i wanted to restore from the back up.

So i did that but silly me forgot that i would have to UNLOCK the simcard again

once the phone started.

I forgot my new SIM PIN at the office but i thought i had

remembered it. So i gave it a try - two failed attempts.

Now before i wanted to risk the 3rd one.

Here is my question:

Did the backup also reset my SIM PIN of my SIM CARD?

Because this simcard was stolen together with my old phone.

Or is the new pin valid, that i got with the new sim card?

Id really appreciated the help!
