My VZW Moto X spits out a "This SIM is from an unknown source" error, followed by "Restricted Access Changed" scrolling across my notification bar when inserting my MetroPCS SIM. I've tried manually selecting the network, and it refuses to connect. I've also tried entering my APN setting manually, but to no avail. So, you guys have any ideas?
I'd post a screenshot in-line, but XDA is being a pain because of my low post count, so check the attachments.
