4G LTE Icon does not light up

[NOLA8DAT]

Hello, I have a DROID MAXX by Motorola.  2 weeks ago I started t received an error message no SIM card.  This started a few days after I did an update.

Call Tech support, they sent out a new SIM card, same issue, still same error message no SIM card.  Tech support said it's a hardware issue.  Sent me a new DROID MAXX, everything was working fine, but now my 4G LTE Icon will not light up.  I tried everything, got it to appear, but now it's not appearing again.  Hope this isn't a dumb question!  Please help, I'm sure it's a simple task.  Also, which text message am I suppose to use, since these updates.  Do I continue with Verizon square red with white icon inside or the new green one.

Thank you!!

I just fixed this issue.  Powered off my phone, pull my SIM card tray out.  Put it back in and turned on my phone and it's all there now.
