Mongolia eSIM questions
How much is an eSIM for Mongolia?
OurByt plans in Mongolia start at $23.99 for 1 GB valid for 7 days. The most picked plan is 3 GB for 15 days at $64.99. Prices are in US dollars, and the app shows the final price before you pay.
How much data do I need in Mongolia?
For a week of maps, messaging, ride-hailing and social media, 3 to 5 GB is usually plenty. If you will stream video, make lots of video calls or work online, choose 10 GB or more. Running low? Add another plan in the app at any time.
When does a Mongolia plan start?
When your phone first connects to a network in Mongolia, not when you buy it. So you can buy before you fly, and the days only start counting once you arrive.
Do I need a new eSIM for Mongolia?
No. You install the OurByt eSIM once. A Mongolia plan, and every plan you buy after it, is added to that same eSIM, so there is nothing new to scan next time.
Does the Mongolia eSIM include a phone number?
No, data plans are data only. WhatsApp, FaceTime and other apps work over the data, your home SIM can stay on for calls and texts, and OurByt calling credit lets you call any phone from the app. You can also add a real US, UK or Canadian number.
Will the eSIM work on my phone?
Most iPhones from the XS onward, Google Pixel 3 and later, and recent Samsung Galaxy phones support eSIM, as long as the phone is not locked to a carrier. The app checks your phone before you pay.
