HTC ONE X: The process "com.android.phone" has stopped?
Ok, so after some extensive troubleshooting I found the issue,

Long story short, you need to have the Snapper application installed.


  
  Snapper Application 


The issue was confirmed to be the combination of the snapper sim and no application when the SIM was switched with a different network, non-snapper SIM, the phone started working correctly.

Next the SIM was put in a different network, vanilla HTC ONE X, the exact same symptoms occurred.

Leading me to the conclusion that it was the difference in the SIM crashing the process.
After installing the Snapper application the process instantly stopped crashing.
