The subject of cell phones on the trail seems to always take on an almost religious fervour on the internet, with rather entrenched positions on both sides of the issue. Personally, I’ve done long hikes with no phone, with a dumb phone, and with a smart phone and there are clear advantages and disadvantages to carrying one.
The weight and the reliability of phones are probably the biggest disadvantage. Personally, I would never trust one to fulfill a mission-critical role, such as navigation, on the trail. I love having the built-in GPS capability and the zoomable maps on a micro-SD chip, but there’s no way that I’d go out on a dubiously marked trail without paper maps and a proper compass. Similarly, while it’s nice to have a copy of a databook or guide on your micro-SD card I would never rely solely on a phone to store that key information as you could end up being unaware of where your next water sources are simply because your phone died.
Setting aside the mission-critical function of navigation, I have found that a smartphone can be very convenient in town, but less useful on the actual trail. Telephone service in town is the biggest attraction because it’s getting really difficult to find pay-phones in the United States, and I’ve found that many cheap motels no longer have land-lines in their rooms (understandably, this is no longer much of a revenue generator). On the trail, I’ve found that phone service is so spotty that it is hardly worth the effort to turn it on. However, it is nice to be able to send a quick text from a location where you are able to get one-bar reception. Other than that, the internet browsing function is a really nice feature to have when you’re in town. Most motels and many restaurants/bars seem to have free wifi, so it’s really handy to keep up with your e-mail and read the news from back home every week.
Overall, I’m a convert. I find that my four-ounce Android phone, its one-once spare battery, and the three-ounce wall charger provide excellent value for their weight. On my next thru-hike, I’ll probably also carry my Kobo Mini to save the weight of a paper book. It uses the same mini-USB charger as my phone, so it’ll be about 3 or 4 ounces but it’ll save me the 12 or 14 ounces that a novel weighs (but again, a novel is not mission-critical).
