Frequently Asked Questions About Mongolia eSIMs
Q1. Will my eSIM Mongolia work in the Gobi Desert?
Mobicom boasts the most extensive network in Mongolia, but coverage in the Gobi Desert mainly focuses on town centers, tourist camps, and major roads. In very remote areas of the desert, you may experience signal loss. Your eSIM will automatically reconnect once you return to a covered area, ensuring you can upload your adventure photos later.
Q2. Can I use my eSIM Mongolia to book a ride in Mongolia?
Yes, your eSIM lets you use apps like UBCab or local taxi services as soon as you arrive at Chinggis Khaan International Airport. With active data, you can book rides, check routes, and manage transport without relying on airport Wi-Fi, making your arrival smoother and more convenient.
Q3. How do I top up my eSIM Mongolia if I stay longer than 16 days?
If your adventure in Mongolia lasts longer than 16 days, staying connected is easy. You can quickly purchase a top-up plan through the SimCorner app, and the additional data will be credited to your account instantly without the hassle of installing a new eSIM. For those on unlimited plans, remember that your high-speed data resets every 24 hours, so a top-up is a great way to extend your overall duration.
Q4. Is the Mobicom network reliable for digital nomads in Mongolia?
Yes, Mobicom offers strong 4G coverage across Ulaanbaatar, with limited 5G available in select central areas. It supports everyday tasks like navigation, bookings, and video calls. Speeds may vary indoors or outside major cities, but overall performance is reliable for short-term remote work and travel needs.
Q5. Do I need a physical SIM card for Mongolia if I have an eSIM?
No, the eSIM Mongolia replaces the need for a physical plastic card. As long as your device is eSIM-compatible and unlocked, you can download the Mobicom network profile digitally. This is especially helpful in Mongolia, as it saves you from searching for a mobile shop in the city and dealing with local registration paperwork or language barriers.
Q6. Will the eSIM work on the Trans-Mongolian Railway?
Yes. Your Mongolian eSIM will work near major towns and stations along the Trans-Mongolian Railway, such as Ulaanbaatar and Sainshand. However, long stretches of the steppe have no coverage, so temporary disconnections are expected. Your device will automatically reconnect once you enter a covered area.
Q7. Is hotspot sharing allowed on the Mongolia unlimited plan?
Yes, hotspot sharing is supported. You can use your daily 3GB of high-speed data for tethering across devices. After reaching this limit, your connection continues at speeds of up to 128kbps. Your high-speed allowance resets every 24 hours, or you can purchase an additional plan if you need more full-speed data sooner.
Q8. Can I use translation apps in rural Mongolian markets?
Yes, translation apps like Google Translate work well in areas with coverage, helping you read menus or communicate with locals. For rural markets or remote regions, it’s best to download offline language packs in advance, as connectivity may be limited outside towns and populated areas.
Q9. What should I do if my eSIM Mongolia doesn't connect upon arrival?
If you don't see a 5G/4G signal after landing at Chinggis Khaan International Airport, first, ensure Data Roaming is turned ON and your eSIM is selected for mobile data. If there’s still no connection, restart your device to refresh the network. Installing your eSIM before departure helps ensure it activates instantly once you land.
Q10. Will my WhatsApp work while travelling in Mongolia?
Yes, your WhatsApp will function exactly as it does at home. Because the SimCorner eSIM for Mongolia provides a dedicated data connection that works alongside your primary SIM, your account remains tethered to your original phone number. You can message, call, and share media seamlessly without losing your chat history or needing to re-verify your account.
Q11. Is my phone compatible with the eSIM Mongolia?
Yes, most modern flagship smartphones from Apple (iPhone XS and later), Samsung (Galaxy S20 and later), and Google (Pixel 3 and later) support eSIM technology. To be certain, your device must be network-unlocked.
Pro-Tip: Dial *#06# on your keypad; if you see an EID number listed, your phone is eSIM-compatible.
Pro-Tip: Dial *#06# on your keypad; if you see an EID number listed, your phone is eSIM-compatible.
Q12. When is the best time to install my eSIM Mongolia data plan?
We recommend installing your eSIM Mongolia before your departure while you have a stable home Wi-Fi connection. While the Data Roaming toggle should stay OFF until you land, pre-installing the profile ensures you have an immediate 5G/4G connection the moment your plane touches down and you switch Data Roaming ON. It helps you bypass the need to connect to unreliable airport Wi-Fi for your eSIM setup.
Q13. Does the eSIM Mongolia come with a local phone number?
This is a data-only travel eSIM and does not include a local Mongolian (+976) phone number for traditional voice calls or SMS. However, you can maintain full voice and text connectivity by using data-based apps like WhatsApp, FaceTime, Viber, and Messenger. This allows you to stay connected with high-speed data without the privacy risks, mandatory passport uploads, or long retail queues associated with local SIM registrations.
Q14. What is covered by the SimCorner 100% money-back guarantee?
We stand behind our connectivity. Our 100% money-back guarantee covers you if your device is confirmed to be eSIM-compatible and unlocked, yet you experience a verified network failure that our 24/7 technical support team cannot resolve. Simply reach out via the
SimCorner App
or email so our experts can assist with real-time troubleshooting or process a prompt refund.
