Mongolia eSIM Data Plans with Promo Codes

Best Overall eSIM for Mongolia

After testing BNESIM on our iPhones and Android smartphones, we instantly knew that it was the best option among others. We ultimately liked how easy it is to set up, which is important for first-time eSIM users. With just a few taps, we got instantly connected online and gathered signals from local carriers in Mongolia like Unitel. But more than the ease of installation and reliable connectivity, there are other features that you can access with BNESIM’s Mongolia eSIM. These include:

• Mobile hotspot (data tethering)
• Optional military-grade VPN (free for automatic plan renewals)
• Optional international phone number with cheap voice plans
• Cashback (for e-Wallet payments)
• Refer-a-friend program: Get 2 BNE Coins (worth €2) for every successful referral
• 24/7 customer support

Moreover, BNESIM offers the largest discount for new users. You can get up to 30% off on their data packs when you book below with our coupon code TRAVLISTS:

Mongolia eSIM with Unlimited Data

We all use data for several reasons: browsing, streaming, social media, communication, work, online bookings, navigation, translation, and more. It is for this reason that we always suggest getting an unlimited data eSIM. This removes the worry of losing data in the middle of the trip (ensuring nonstop connectivity) and having to top up the eSIM with another data plan (which may be more expensive).

Yesim and GigSky are the two top providers of Mongolia eSIMs with unlimited data. Use either one, and you can enjoy a smooth internet connection. However, if we can only pick one, we would go with Yesim. That’s because their embedded SIM also comes with a free VPN for iPhones, handsome cashback offers, and easy installation — you get more bang for your buck. Plus, they offer a $6 discount, which you can avail by using our Yesim coupon code TRAVLISTS2025.

Mongolia eSIMs with Phone Number, Calls, & Texts

Suppose you need a secondary line to contact local or overseas numbers, you can save money by getting aloSIM’s Mongolia eSIM. Their data eSIM comes with a free international phone number as well as voice and SMS credits. This is ideal if you need to dial family, friends, or colleagues back home, or make calls to businesses in Mongolia.

Another eSIM that you can consider is Roamless. While their Mongolia eSIM does NOT come with a phone number, you will be able to make calls to over 200+ destinations for as low as $0.01 per minute. (Plus, they offer a free trial.)

Regional eSIM for Mongolia by Ubigi

If Mongolia is just one of the countries that you will visit in Asia, you can get a single eSIM that works in various countries instead of buying multiple ones. This will save you money.

In this article, our team has listed all great and affordable options for Asia eSIMs. However, Ubigi’s Asia eSIM is what we would recommend for Mongolia-bound travelers. It starts at only $3, connects to the Unitel network in Mongolia, and works in 25 more countries, including China, South Korea, Nepal, Kyrgyzstan, and more.

Top Mongolia eSIM Providers with Reviews

When choosing an embedded SIM or digital SIM card for Mongolia, you’d want to get one that connects to any of these domestic carriers: Unitel, Mobicom, or Skytel. This will ensure that you get the same optimal internet experience that locals enjoy. Below, we have a shortlist of digital SIM card providers that connect to these networks, along with a description of their eSIMs’ key defining features.

1. BNESIM

I have been using BNESIM for quite some time now (around two years), so I could say I am quite familiar with this provider. As I mentioned earlier, I really like BNESIM for how easy it is to set up, how it connects to local networks (Unitel in Mongolia), and how it is capable of mobile data sharing. The data connection has always been so strong (based on my experience in Asia, North America, Oceania, and Europe). But the reason why I prefer BNESIM is that it’s so affordable yet packed with so many features. With BNESIM, I can run a VPN to add another layer of security when I go online. I can also activate my international phone number whenever I need to make local calls (paid add-on). Needless to say, if there is only one eSIM that I can recommend to friends and families, this would be it.

However, the main reason why my friend keeps recommending this provider is for their handsome cashback offers. The more you use Airalo, the higher the cashback you get for your purchase.

This is ideal if you plan to have a multi-country adventure and want to save money — instead of purchasing multiple eSIMs, you can purchase just one regional eSIM. The reason why we like Ubigi is that it works in 25+ countries including Mongolia, gathers signals from local networks, and starts at only $3.

They have great coverage not just in Mongolia and other countries, but also on water (with their innovative cruise plans) and up in the air (with their flight plans).
