Every time I reboot my M7 HTC One with Viperone 6.1.0 it shows a data connections for just a moment, then it drops out and a "Sim Card Inserted" notification pops up where you have to choose your carrier. I've tried full wipe and reinstall 3 times now, as well as removing the sim and rebooting and reinseting several times. I'm upgrading from Viperone 5.8 with the same sim card that has worked fine for a few months now. I'm also using DarkOne theme but I don't think it has anything to do with the issue. The issue is present whether or not I restore my account and apps. Does anyone out there have a suggestions for a fix?
