EC25 - Not returning RDY?

Is it normal for the EC25-AF(D) device not to return RDY?

Firmware version: EC25AFFDR07A07M4G_01.003.01.003

Using the EC25-AF myself, I am not understanding, what you are asking for. Pls, elaborate.

When you are listening to UART or using QCOM, does it output ‘RDY’? My BG95 does but my EC25 doesnt.

Sorry, I do not know this functionality from my EC25-AF(s), because using them with openwrt+QMI. Not permanently listening on a port. I am checking readiness using AT+QINISTAT, after resetting modem.
