If you have recently dropped your phone on the ground (or other similar situations) and your iPhone can't use cellular data at this time, then you should consider that this could be the result of a loose SIM card.
Additionally, not cleaning the card slot for a long time may cause dust to accumulate inside, which in turn may affect the device to recognize the SIM card. This is when you need to open the card slot using the “SIM Ejector Pin” and check it. After cleaning the slot and double-checking that the SIM card is not damaged, reinsert the SIM card and make sure it is firmly inserted. Then turn on the iPhone and test if the cellular network is available.
