For anyone interested I am running both Verizon and AT&T simultaneously on this phone. I have had it a couple of days now. Verizon works only in Sim 1. I tried it alone this morning and without wireless downloaded a scanned 40 page pdf in seconds. WhatsApp appears to work as well on both lines. I am also using the Xiaomi Mi5 for the same thing. The Axon 7 is superfast and strong compared to the Xiaomi but the Xiaomi seems to use the two cards a little easier. It may just be my imagination, but the bottom line is that both phones seem to work fine with one sim card from each carrier. I took my sim card from a Nexus 5x and the AT&T card from a Windows Lumia 950, popped them both in and there you go - two networks on one phone.
Are you able to switch to using only your AT&T data (4G/LTE) when you are running on both AT&T and Verizon?
