In case of an emergency, dial 911. Cellular service is extremely limited in Yellowstone. Cell towers at Mammoth Hot Springs, West Yellowstone, Old Faithful, Grant Village, Lake Village, and Mount Washburn provide service to most developed areas and to the North and West entrances. Check with your provider to verify coverage. During summer the number of users can overwhelm cellular circuits resulting in an inability to send or receive calls, text, or use cellular data. Texting is usually the most effective means of communication in the park. Cellular service is available in most nearby communities and along some of the major highways leading to the park, however, areas without coverage exist throughout the region. Free public Wi-Fi is available at the following visitor centers: Albright Visitor Center, Old Faithful Visitor Education Center, and West Yellowstone Visitor Information Center. It's also available at some of the hotels and lodges around the park for registered guests of Yellowstone National Park Lodges. Gas stations can be found at Canyon Village, Fishing Bridge, Grant Village, Mammoth Hot Springs, Old Faithful, and Tower Junction. All service stations offer 24-hour, year-round credit card fueling. View the operating dates for additional information. Electric vehicle (EV) charging stations are extremely limited inside Yellowstone. If you choose to drive an EV into the park, plan accordingly.
There are 9 lodges and 12 campgrounds within Yellowstone National Park, as well as additional lodging options in the communities outside of the park. 
Nothing compares to sleeping under the stars! Most park campgrounds are reserved and full far in advance—plan ahead for a successful visit!
