I only emphasize that because I only can answer definitively for the airspace I have actually flown in, which does not include the NOPAC fixed route structure. I can tell you for sure that you can file and fly without datalink on most of the Pacific track systems including the very busy fixed routes between Hawaii and the West Coast of the USA.
