I have a Nexus 5 and I'm on the Sprint network. I've had the phone since the first day it was available at Best Buy and within the last week I've been getting this error, "Sim card removed. Must restart phone to connect to the network." Or something along those lines. I'll hit restart and get the error 3 or 4 times. It's been happening randomly, but frequently. I've never removed the sim card and haven't added any new apps. I've had almost all the same apps from the beginning.
Suggestions? Thoughts? If nothing else I guess I'll see if I can't get it exchanged.
