My girlfriend’s Moto G1 (no Sim card) on the 1.0 has started getting “No Sim Card - Emergency Calls Only” messages. The first time it happened, I looked here and it seemed that Facebook and Messenger were problems. I went through the uninstall procedure suggested, then reinstalled Facebook and everything seemed to work ok…for a while. Her phone started scrambling her contacts, so I uninstalled Facebook again. After restarting, the “No Sim Card…” message reappeared in the notification area for a while, then went away.
Just a little while ago, there was nothing on her phone, just the background image. Again, I cycled power and the icons came back, but again the “No Sim Card…” message appeared for awhile (3 or 4 minutes).
Any suggestions? She’s a heavy Facebook user but doesn’t have many other apps installed. If this can’t get resolved, she’ll probably be going elsewhere. She’s showing amazing restraint.
