Can I receive SMS in airplane mode?

I can't. Mobile phones can't receive short messages in airplane mode. In flight mode, the GSM or GPRS module of the mobile phone is turned off, so that the mobile phone will not actively send paging signals to the base station, that is, it will not try to contact the base station, so it cannot answer calls or send and receive short messages. However, you can make an emergency call, because in this mode, the principle of making an emergency call with a mobile phone is similar to that without a SIM card.
