Sim card locked

I am getting a "Sim card Locked" message on my samsung galaxy s7 phone.  I have tried multiple things already. I have contacted my phone carrier and nothing seems to be helping.  I am looking for some new ideas to try.

What did the ISP tell you?

Do you fave a decent backup? So then could you do a factory reset

After X number of incorrect pin entries the sim is disabled.  This is a security feature, you have to replace the sim card

Agree and your ISP should have told you this.

You need your PUK

Contact your carrier again.
PUK = Personal Unlocking Key (usually 8 digits).
PUK code is a second security code for your SIM card
It relates to the SIM card - not the phone

If you go to the website of your mobile provider, there is usually a "PUK" link.
You will have to login to get your PUK code.
You may need the SIM card number. (Use a magnifying glass on the SIM)

When you get your PUK, just enter the code when the phone requests it.
If you enter the wrong 4 digit PIN of the SIM too many times,
you will need your long PUK to unlock your SIM.
(The PUK will allow you to set a new PIN for the SIM).

Repeated incorrect attempts (usuallly 10) in entering a PUK, will totally lock the SIM card.
You would then have to get a new SIM card.
