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.
