Non-digits in +CCID response


M66_Series_AT_Commands_Manual says that CCID may contain non-digits:

AT+CCID // Query CCID of the SIM card
+CCID: “898600220909A0206023”

It is a real example? As far I know, ICCID should be treated as decimal number.

Same ICCID used in +QCCID example.

Dear Alex,
Yes, it is just an example. You can use the command to check the CCID of your SIM card. Thanks!

It is slightly not correct example.

Thanks, i will be know.
