cell phone service in N.W Wyoming

We have service with Verizon Wireless. When we were there in 2013, we had cell service in the Tetons (Colter Bay) which was good for voice, but marginal for data. At Yellowstone, we had no cell service except at Old Faithful. Again, voice OK, but data marginal. I understand that there is now a new tower in the Fishing Bridge area, and things have likely changed if true. I suspect you'd have better service if staying at West Yellowstone. Hopefully there's someone else on this board that has more recent experiences that mine.

Verizon added a new tower at Fishing Bridge in Yellowstone in September 2014

We had great service there

As Ichin says, it is patchy at best in the YS park. That was in 2014. I don't remember what was in Grand Teton. At Fishing Bridge, I was lucky to pull 1X (do you even remember 1X?)and that was not reilable. We spent a day in Mammoth. We had solid 4g there. Like you, I had a lot of business to conduct and it was a PITA, but without a towed it was not worth being outside YS.

If you really want to be in the park and you really need data, investigate renting a satphone that has data capability but test it before you go. I had one that was good. A friend got one that was worthless.

No, there is not decent cell service; 95 percent of the area you will not get cell service. I have no problem with that.

I take my work with me and have to be on the phone and computer to close and broker deals. I got Verizon and AT&T providers. will there be signal or am i OFF the GRID?

Cell phone coverage is spotty, yet reliable depending on the spot.

Old Faithful -- yes, you have coverage within about a mile of the Visitor Center

Lake and Canyon -- again, depends on where you are

Grand Teton -- yes and no, depending on where you are.

So, if you are looking at Verizon, if you find the Verizon cell phone coverage map online, it is reasonable at letting you know about where the coverage is.

I'm able to schedule my trips so that I can work from where I'm camping but not as much while seeing the sites.
