Two very different pictures
Connectivity in Mongolia depends heavily on where you are. In Ulaanbaatar and other towns, mobile service is generally good and many places offer wireless internet. In the countryside, coverage is uneven: a signal may be strong at one hilltop, weak in the next valley and absent for hours of driving. Because the country is so large and sparsely populated, there are many areas with no signal at all. Details change as networks expand, so treat this as a general picture and check current information.
Coverage in cities and towns
In the capital, expect fast enough mobile data for maps, messaging and video calls most of the time, along with wireless networks in hotels, guesthouses, cafes and some public places. Speeds and reliability vary, and heavy use at busy times can slow things down. In provincial centers, service is often available, but quality can differ from the capital. Hotels and guesthouses in small towns may offer internet that is slower or intermittent.
Coverage in remote areas
Outside towns, you will often lose signal on stretches of road, at ger camps and in national parks. Some camps have a little signal in a particular spot, such as the top of a nearby rise, and some have none. Herder families may have a phone and, occasionally, solar power for charging, so a ger without electricity does not necessarily mean no phone. Do not plan around being reachable. If someone at home needs to know you are safe, tell them in advance that you may be out of contact for several days at a time.
Local SIM cards or roaming
Visitors usually have three options:
- Use international roaming from your home provider. This is convenient but can be costly or restricted, so check your plan.
- Buy a local SIM card, which can be a good value for data. It generally requires an unlocked phone, and you may need to show a passport. Shops are available at the airport and in the capital, but details of what is sold and how to register change.
- Use an eSIM from a provider that supports Mongolia, if your phone is compatible.
Whichever you choose, set it up before you leave the city when you can still ask for help. Mongolian network operators and plans change over time, so rely on current local advice rather than fixed details.
A local SIM does not fix a lack of coverage in remote places. The network you pick may have somewhat better coverage in some regions than another, and it is worth asking your driver or guide, who may know which works best along your route.
Preparing to be offline
A little preparation makes remote travel smoother:
- Download offline maps of the areas you will visit, and confirm they work without a connection.
- Save key documents, such as passport copies, insurance details, bookings and emergency numbers, on your phone and on paper.
- Download translation tools and a language pack. Learning some Mongolian phrases and the basics of the Mongolian language helps when the phone cannot.
- Pre-load music, books or podcasts for long drives.
- Share your route and expected dates with someone at home.
Power and charging
Charging can be an issue outside towns. Ger camps may run generators or solar panels for limited hours, and families may have little spare power. A power bank is a very practical item, and a car charger can help during long drives. Bring the right plug adapter, and check the voltage of your devices. The packing list article covers other equipment.
Emergencies and safety
If you plan hiking or horse trekking in remote areas, a satellite communicator or similar device can add a measure of safety, but it is not a substitute for planning, a competent guide and appropriate insurance. Do not assume you can call for help from anywhere. Learn the emergency numbers and ask your guide what the plan is in an emergency, and read about travel insurance and emergency planning.
Etiquette with phones
Photography and phone use should be respectful. Ask before photographing people or the inside of a ger, and put the phone away during meals and conversations with hosts. Drone rules, where applicable, vary, so check them before bringing one. A quieter, less connected stretch can be one of the pleasures of the trip, and many visitors come to value it.
