There’s no reason to be stuck with unreliable service, dropped calls, and data that slows you down. Triangle Mobile is a local provider that knows good coverage is most important closest to home. That’s why we provide the best coverage—hands down—on Montana's Hi-Line, building towers where the big guys won’t. But that doesn’t mean you’ll be stuck when you travel: our national partnerships let us offer the same nationwide coverage you’ve come to expect. We offer the latest phones and local customer service from people who are true Montanans, just like you.
