I have a Huawei - Honor 9 Dual Sim, SFT L09 with a SIM card from Swisscom, Switzerland
I'm in Vermont during the summer.
The phone does not work here with ATT 3 G and 4 G, it works with T Mobile 2G. What's the problem?

It should work on 3G, change sim slots. (One sim slot is probably 2G only)
ATT has no 2G network (T mobile won’t much longer either).
The specs list 3G bands 850 and 1900, you need BOTH in the USA to get 3G talk and text.
You don’t have enough LTE bands in common with US carriers to get LTE.
ATT uses 2,4,5,12/17,30 and 66
