Having issues with SIM reading

I've always had this issue with my FE that I got 4+ years ago and it's not all the time but it's fairly often that it'll randomly tell my I don't have a SIM inserted and I just don't have data, the fix to this is usually taking out and re-inserting the sim or restarting the phone multiple times. It definitely is a physical problem with the phone rather than the SIM card since it looks perfect and everything looks fine. I don't wanna get a whole new phone because of this since this phone hasn't slowed down at all since I got it but it's extremely annoying. Does anyone else have this or have heard of this issue?
