Recently my smart phone has been doing strange things. I'll look down, and I'll get an error message saying "SIM card removed -- Unable to detect your SIM card. Your device will restart to check for your SIM card.", or something along those lines. No, I didn't open up my phone to actually remove my SIM card. It just does this magically on its own. Unfortunately, this means people can be trying to call or text me and I won't get any notice of it because my phone is in this "SIM card removed" state. Rebooting fixes the problem temporarily, but I wanted to try to fix this problem before I consider buying a new phone.
These are the times I ask that all-important question: "Hmm, what would MacGyver do?"
So here's a solution I found on-line, and worked on tonight:

You'll need scissors, a micro screwdriver, and a foam earplug. Of course, MacGyver would just use his Swiss Army Knife for the first two.
So far, so good. We'll see over the next few days if this really worked.
