I've spent several hours reading about the problems people have had with the switch to KitKat. My phone never shows the "no sim card" or anything of that nature. The triangle where the bars should be just goes completely empty. I'm just curious if this is known to be a software problem and not a hardware problem. I just came from a really really low end smartphone that would cut itself off on a daily basis. I need this phone to at least maintain normal functionality for a while. I don't have a phone to put the Straight Talk sim card in to check and see if it's the problem.
I don't really want to send the phone back, even though I've looked at the Nexus 5. It's a little bit out of my price range for a phone. Thanks in advance for your help.
