Triangle is working to bring our customers the best mobile service, in Montana’s beautiful wide open spaces.

What our customers say

We switched to Triangle after seeing that there was service all the way up to the Canadian border. We love the coverage we now have with Triangle. Dead spots are fewer and fewer! And they have everything all the other competitors have. We would never go back.
