Your validity window starts when the eSIM first connects to a network in Mongolia, not when you buy it — so you can install it before you fly and it only begins on arrival.
Will my phone work in Mongolia?⌄
You need an eSIM-capable, carrier-unlocked phone (iPhone XR+, Pixel 3+, recent Samsung Galaxy). Check the compatibility page before you buy — and if it turns out your phone can’t use it, you get a full refund since nothing was installed.
Can I keep my number and WhatsApp in Mongolia?⌄
Yes. Your vigxo plan is data-only, so your primary SIM stays active for calls, texts and your usual number. WhatsApp, iMessage and all your apps keep working over the eSIM data.
What if I run out of data in Mongolia?⌄
If your plan supports it, you can top up an active eSIM in seconds from your dashboard — no reinstall needed. Otherwise just buy another plan; it stacks onto your eSIM.
How do refunds work?⌄
Full refund any time before installation, up to 120 days from purchase. Once an eSIM is installed the data is released to you, so it can’t be refunded after that.
Setup
Land in Mongolia already connected
Set up your eSIM before you travel — it takes about a minute. Scan once, switch it on when you arrive, and you’re online.
On iPhone (iOS)
1After purchase, open the confirmation email and tap the install link — the eSIM adds itself (iOS 17.4+). Older iPhone: Settings → Cellular → Add eSIM → scan the QR from the same email.
2Label the plan (e.g. “vigxo travel”) and set your home line to keep calls/SMS.
3Turn on Data Roaming for the vigxo line — this uses the local partner network, not your home carrier.
On Android
1Tap the Android install link in your email (recent Android) — or Settings → Network & internet → SIMs → Add eSIM and scan the QR.
2Download the profile and set vigxo as your Mobile data line.

How eSIMs work in Mongolia
A travel eSIM for Mongolia is a digital SIM your phone downloads — no plastic card, no airport pickup counter. You buy online, tap the install link we email you (a QR code is included too), and it installs a second line alongside your existing SIM. It stays dormant until you arrive in Mongolia, then connects automatically to Mobicom on 5G where available and LTE everywhere else. Your home number keeps working for calls and texts; the eSIM simply carries your data.
How much data do you need in Mongolia?
Maps, messaging and rideshare apps are light — roughly 300–500 MB a day. Add photos, social and the occasional video and you’re closer to 1 GB a day. For a one-week trip a 5 GB plan is comfortable; for two weeks, sharing, or heavy use, choose 10 GB or more, or a reloadable plan you can top up on the go. Mongolia plans start at $16.99 across 8 sizes, with the per-GB price shown on every one so the right choice is obvious.
Will you pay roaming charges in Mongolia?
No. A travel eSIM for Mongolia is a local data plan, not international roaming — you pay the price you see up front, with no per-megabyte bill from your home carrier. Set the eSIM as your data line and switch data roaming off on your home SIM, and there are no surprises when you get home. Full refund any time before you install, so there’s no risk in buying ahead.
