IPhone 4s says "Invalid SIM" with IOS 7.1

-0001-11-30 | Default

I have an unlocked Iphone 4s for T-mobile which allowed me to use the iphone on a metropcs plan with a metro SIM card. I switched to metro on Sunday, today being Tuesday, and it worked perfectly, perfect 4g, perfect T-mobile carrier. Yesterday, Monday, I took a trip to publix and my phone read "No service" and I figured it was an itch and I had no service in publix. But this morning, Tuesday, it still read "no service" even at school, which worked fine on Monday. So I restarted my iphone and then it read "Invalid SIM" and I looked up how to fix that: restarted it by taking out sim and putting it back in, didn't work. Airplane mode on/off, didn't work. Then I read to update completely, to IOS 7.1, which I did and it still did not work. I cleaned my SIM card, didn't work. Reset all settings, didn't work. I read all over that the SIM card may be damaged due to the updates but my sim card wasn't working even before I updated. I'm currently about to restore my phone in hopes of fixing it sigh, but tomorrow, if still not working, I will take it to metro and request a new SIM. Any other ideas guys :---(

Hi,
I also noticed a SIM related problem iPhone 5 after upgrading to IOS 7.1.
It does not happen consistently, but I noticed that in certain times, iPhone "reception signal level" turns into "NO SIM" or "No SIGNAL" although SIM is perfectly fine and singal strength is high.
I have no idea why it happens, but it started only yesterday after I upgraded to IOS 7.0.1.
Apple engineers, please check this.
Thanks,
Daniel
