End of AT command responses

Hello
I have Quectel EC25 modem, and I want to know is there a static structure for the end of the at-commands response? For example does at-commands response always end with OK or other words?

static const char * s_finalResponsesError[] = {
“ERROR”,
“+CMS ERROR:”,
“+CME ERROR:”,
“NO CARRIER”, /* sometimes! */
“NO ANSWER”,
“NO DIALTONE”,
};

static const char * s_finalResponsesSuccess[] = {
“OK”,
“CONNECT” /* some stacks start up data on another channel */
};

Thank you very much WizIO, Is there another final answer?
