after calling palco they agreed to replace the mainboard as i was apparently still in warranty. i noticed calls made in my call log and when i talked to them they said they were able to successfully make calls and were unable to replicate the problem with both a tmobile sim and att. now i have a new main board and sim problem is gone but now it randomly reboots cat /proc/bootreason says sw_rst. reflashed firmware and emmc and issue doesnt go away
