i think it's EVRC-N + not even proper pcs, it was on 800, (even though field test call the channel *PCS* as though it were 1900)
i went back to check, this time in signalcheck pro, calling the house again.. check this out.. -
then -
the nexus 5 is set to *lte only* in prefered network type
& *automatic* in system type (i think it helped with the phone app freezing on incoming calls related to e-csfb)..
but anyways, my former photos IS NOT proof of HD calling through the higher 1.9 channel.. but i'm not saying it's not happening based on that..
