There are many sites to do this. https://willmyphonework.net/ is very often linked but it seems your phone is not found by them (or I might've missed it). https://www.frequencycheck.com/search?s=+ASUS+ZENFONE+MAX+PRO+M1 seems to list ... all of them. This points out a different problem: a marketing name like this often tells you little and you need to know a lot more. This site lists eight different models. Your "about phone" screen and if that's still not enough, then xda forums are the best bet in figuring this out.
To add to the merriment, there are many LTE bands used by a carrier and if a frequency check says some but not all bands are supported then you will have no idea whether the place where you go to will have coverage or not because not all bands are used everywhere...
