SIM is from an unknown source when using a non-VZW sim has started happening since flashing 4.4 on my X. It happens on my Galaxy S4 too. I haven't tried on my GS5.
I no of know way around it.
For Metro PCS, at one time they were a CDMA carrier like Verizon. Do they use CDMA in your area still, or are they now GSM only? If they use GSM only, your APN settings must be EXACTLY correct for them to work. If they still use CDMA, then there are some underlying CDMA/EVDO settings on your phone that will likely need to be changed. I know I saw some threads about using QPST and other tools to make edits for other CDMA carriers, but I've not seen it for MPCS.
