Exactly! I had to get a new SIM because my old one was a micro and my new phone needs a nano.
Also, you might want to try a different SIM card altogether to see if the problem is with your SIM or the phone itself. It’s a good troubleshooting step!
That’s a smart move! I’d also recommend updating your phone software, as outdated versions can cause issues with SIM recognition.

I have Android 10 and haven’t faced such issues. Just curious, is your device generally performing well?

I’m curious, did you recently change carriers? Sometimes, carrier settings need to be adjusted after a change. Just a thought!
That’s a valid question! It seems like a lot of problems stem from carrier settings.
Am I the only one who thinks that inserting a SIM card should come with an instruction manual? 
It’s like a game of Tetris!
Haha! Right? Sometimes I feel like I need a degree in engineering just to swap SIM cards!
I faced the same issue last month! I removed the SIM card and cleaned the metal contacts. That fixed it quickly.
Thanks for the tip, Margaret! I’ll try that. It sounds simple enough.
In my case, the SIM card was just misaligned. I popped it back into place and everything worked smoothly again.
I recommend checking if your phone’s software is up-to-date. Sometimes, an outdated OS can trigger such errors.
Elainesnyder, that’s a good point! I often forget updates can cause issues like this.

If cleaning and realigning don’t work, you might need a new SIM card. It happened to me, and it solved the problem instantly.
That’s true! I wasn’t sure if it was a card issue or just my phone being difficult.
Sometimes it’s the SIM tray itself that’s faulty. I had to replace mine too at one point to get rid of the error.
Great advice here! Just remember to check your phone’s warranty; you could save some cash with repairs.
Has anyone also had experiences where restarting the phone resolved this? It worked for my friend once!
Yes, restarting helped for me too! But I did feel silly after trying so many fixes before that.
