Non-digits in +CCID response

IoT Modules GSM Module
1

hello!

M66_Series_AT_Commands_Manual says that CCID may contain non-digits:

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

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!
