Yes. There are two ways to get your photos back: 1) Repair your phone and get all your photos via USB/Google Photos/whatever you prefer. 2) Find someone to recover your photos from the internal storage directly. Even if your phone is completely dead, chances are the eMMC/flash chip is still alive. This won’t work if you’ve enabled encryption.
I guess it might be the antenna, SIM slot or something severe, like damaged motherboard. Or it could be something with the SIM card itself. Try to remove SIM card from the phone and then put it back in. Does it go from “No SIM” to “No Service”? Can you also try a different SIM card?
