There is a way to check which format your phone has.You go into "MY Device"and have to wade around thru it, but it is there. Too complicated for me to explain,buy I did it. My Samsung is the Verizon format. I learned a lot on this thread. .
Now I think it doesn't matter which one you have if you travel around much. Some areas must have the Verizon towers, some must have AT&T. Up in northern Colorado they must have more AT&T because I can't get s cell service where I hunt. Down in South central Colorado , I get it great as long as I am in LOS. LG phones might have AT&T format as my buddy gets signal up north were we hunt. You might have to figure out a way to check the phone before you buy it or buy one of each
Along major corridors like I-70 and I -25, they must have both because in never have trouble.
