Here's my take on how I see things: I think the 3G Plans are way too Vain, and perhaps out of sync with the realities we face.
Here's what I would have done differently:
IF 4G speeds were let's say, 51MB, I would cap at let's say 31MB, a Middle of the ground approach
Let's say, Prov-Wide+Global Txt+4GB under 3G was $57for 30 Days, and the LTE $80,
What IF Take that same plan, BUT under 4G, BUT no LTE, and 31 instead of 51MB, $55, LTE Version $75, would that be fair?
90 Days:
Let's say, Prov-Wide+Global Txt+6GB under 3G was $141
Take same version, just LTE, $180
Prov-Wide+Global Txt+6GB under 4G $140
Same version BUT LTE, $152
Can-Wide+Global Txt+6GB under 3G was $156
LTE Version $195
Can-Wide US+Global Txt+6GB under 3G was $171
LTE Version $210
Can-Wide US+Global Txt+6GB under 4G $170
LTE Version $185
4G version: $155
LTE Version $172
