I don't know what the modern commands look like, but I hope that at least they abolished the in-band signalling so you don't have to do <wait 1 second> +++ <wait 1 second> .
For newest Quectel BG95 LTE Cat M1 you can either use buffer access mode (AT+QIRD for receiving data) or still use that in-band signalling (direct push mode) with +++. You could also use external pin for exiting from that direct mode, but +++ is still available and useable when you don't have any more free pins on your MCU.
