This is an excellant point. Att has terrible service in many remote areas, verizen is better, Sprint etc are in my experience urban and interstate phones. When do you need GPS help? In the city they phone gps works great unless your wife is using it to call the kids. In the bush of Alaska or colorado, not so much. My Garmin works anywhere except hi rise buildings and tunnels. It gets it signal for the sats and does not rely on cell service to work.
Don't over think this. Listen to people you know and go with what they suggest. Basic GPS units are not expensive anymore. You can get a unit with great features for less than $200. Get one and work with it or better yet borrow a unit from a family member or friend who has upgraded. You'll be better prepared for your 2nd purchase based on your first experience.
Just get started.
