About the operator
MobiCom is Mongolia's first and largest mobile operator, founded in 1996 as a Mongolian–Japanese joint venture of Newcom, Sumitomo Corporation and KDDI. KDDI took a majority stake in March 2016 and has run MobiCom as a consolidated subsidiary since, with Sumitomo as partner. It launched the country's first mobile service and today runs 4G LTE in Ulaanbaatar, the provincial capitals and along the main roads, with a dealer network that reaches the countryside.
For visitors MobiCom sells a Tourist package — data-only, as an eSIM or a physical SIM, bought on mobicom.mn with an email address and a card. AviaeSIM's Mongolia eSIM is another online route, with plans on MobiCom or Skytel as each plan card shows, bought before the flight and installed by QR code.

How to get the official MobiCom eSIM: price, QR code, registration
MobiCom sells its own Tourist package, and its support page says the package can be bought on the MobiCom website as an eSIM or a physical SIM. On 26 September 2026 the page listed three data-only packs: 15 GB for 7 days at 20,000₮ (about $5.80), 25 GB for 15 days at 30,000₮ and 50 GB for 30 days at 60,000₮. To buy, choose a pack, pick eSIM (a list of compatible phones appears) or physical SIM (you enter the number printed on a blank MobiCom SIM), confirm your email with a one-time code and pay by card — the only payment option — after which the eSIM details arrive by email. The validity starts when the pack is activated, and a pack bought online is cancelled if it is not activated within 30 days. The Tourist number cannot make or receive calls except to customer service on 2222, and MobiCom's branch at New Ulaanbaatar International Airport gives arrivals a free SIM with a 1 GB bonus.
AviaeSIM's Mongolia eSIM is the alternative: plans on MobiCom or Skytel, as each plan card shows, paid by card, delivered as a QR code in minutes and installed before the flight.
MobiCom local SIM vs AviaeSIM
| MobiCom Tourist package (eSIM or SIM) | AviaeSIM travel eSIM (Mongolia) | |
|---|---|---|
| Price per GB | About $0.35–0.40 per GB on the Tourist packs (15 GB for 20,000₮, 50 GB for 60,000₮) | Plans for Mongolia from $3.67; the price per GB is on each plan card |
| Activation | Bought on mobicom.mn with an email code and a card; the eSIM details arrive by email and the pack runs from activation | QR code by email; installed in the phone's settings in about two minutes |
| Passport registration | Not asked for in MobiCom's online Tourist purchase (email and card); guides say a SIM bought in a store is registered to a passport | None; only an email address at checkout |
| Validity | 7, 15 or 30-day packs; an online purchase not activated within 30 days is cancelled | Fixed validity per plan, counted from the first connection in Mongolia |
| Support | MobiCom customer service on 2222 (press 2 for English), branches and the app | AviaeSIM support by email, before and during the trip |
| Best for | Long stays and heavy data use on a budget, with no need for calls | Short visits, or unlimited data on the Skytel plans |
Checked 26 September 2026 on MobiCom's Tourist service page (support.mobicom.mn: packs and prices, online eSIM purchase, data-only number, airport SIM offer); the passport rule for store SIMs comes from an August 2026 Mongolia SIM guide — confirm in the store.
Network & technology
MobiCom runs 4G LTE across Ulaanbaatar, in the aimag centres such as Darkhan, Erdenet, Khovd and Mörön, at the new Chinggis Khaan international airport and along the paved roads between them; 3G and 2G fill in the towns beyond. On the steppe between settlements and in the Gobi the signal disappears for long stretches on any network, so a trip to the countryside needs offline maps. AviaeSIM's Mongolia eSIMs connect to local networks — the fixed-data plans list MobiCom, the unlimited-data plans Skytel — and each plan card names the network, so check it if MobiCom's footprint matters for your route.
Reputation & market position
MobiCom is the incumbent with the widest footprint and the airport branch most arrivals see first; Unitel is its main rival, with Skytel and G-Mobile smaller. Its tourist packs are cheap per gigabyte by any standard. The friction points for visitors are that the Tourist number is data-only — it cannot make or receive calls except to MobiCom's customer service on 2222 — and that the app, the top-up vouchers and much of the website are in Mongolian first.
Pros
- Official Tourist eSIM sold on mobicom.mn — no store visit needed
- Cheap tourist data: 15 GB for 20,000₮ over 7 days, 50 GB for 60,000₮ over 30 days
- Free SIM with a 1 GB bonus at the MobiCom branch at New Ulaanbaatar International Airport
Cons
- The Tourist number is data-only — no calls except to MobiCom customer service on 2222
- A pack bought online is cancelled if it is not activated within 30 days
- No signal on most of the steppe and in the Gobi between settlements

Frequently asked questions
Does MobiCom have an eSIM for tourists?
Yes. MobiCom's Tourist package can be bought on the MobiCom website as an eSIM or a physical SIM: pick a data pack, confirm your email with a one-time code, pay by card, and the eSIM details arrive by email. The Tourist number is data-only — it cannot call anyone except customer service on 2222.
How much does a MobiCom tourist eSIM cost?
MobiCom's Tourist page lists three data-only packs: 15 GB for 7 days at 20,000₮ (about $5.80), 25 GB for 15 days at 30,000₮ and 50 GB for 30 days at 60,000₮, whether you choose the eSIM or the physical SIM. An eSIM for Mongolia from AviaeSIM is priced per plan on the cards.
Can I buy a MobiCom eSIM online before I land in Mongolia?
Yes — MobiCom sells the Tourist eSIM on its website with an email address and a card, and a pack bought online must be activated within 30 days or it is cancelled. AviaeSIM's Mongolia eSIM is another online option, with plans on MobiCom or Skytel as each plan card shows, delivered as a QR code and installed before the flight.
Does a MobiCom eSIM work outside Ulaanbaatar?
Wherever MobiCom has signal: the provincial capitals, the airport and the paved roads have 4G, the smaller towns 3G, and the open steppe and the Gobi have nothing between settlements on any network. Download offline maps for a countryside trip; the eSIM reconnects when you reach the next town.
MobiCom tourist eSIM or a travel eSIM — which is better for Mongolia?
MobiCom's Tourist packs are cheaper per gigabyte and sold online, so for weeks of heavy data use they are hard to beat, as long as you do not need calls — the Tourist number cannot make them. A travel eSIM such as AviaeSIM's suits a short visit, or unlimited data on its Skytel plans.
