be used:

Please note that in this case the mobile does not finish its response with the OK string.
The response +CME ERROR: 13 (SIM failure) is returned after 10 unsuccessful PUK
presentations. The SIM card is then out of order and shall be replaced by a new one.
Example: 3 failed PIN validations + 1 successful PUK validation
