I'm not sure how accurate this site is, but it's claming that the MX4
hardware supports more US bands than Pro 5:

MX4: https://www.frequencycheck.com/compatibility/48v7ir8/meizu-mx4-m461u-td-lte-32gb/united-states

Pro 5: https://www.frequencycheck.com/compatibility/Ealeulv/meizu-pro-5-ubuntu-edition-m576-dual-sim-td-lte-32gb-meizu-niux/united-states

Namely, Pro 5 supports no US 3G bands and only single LTE band on
certain operators, while MX4 has some 3G coverage.
