TL;DR
- If you’ll stay more than a few days, a local SIM is usually the best value.
- Buy at an official store/kiosk if possible (less confusion).
- Ask for a data-heavy plan; most visitors care about data, not minutes.
What to do (step-by-step)
- Decide: eSIM vs physical SIM (depends on your phone and what’s available locally).
- Go to an official shop/kiosk (airport or city).
- Ask for: “tourist SIM / data plan” and show your phone.
- Before leaving: confirm data works, not just signal bars.
What to ask for (simple phrases)
- “I want a SIM with data.”
- “How many GB?”
- “Can you activate it now?”
Common mistakes
- Leaving the shop before testing data.
- Buying from a random reseller with unclear pricing.
- Assuming you can rely on café Wi‑Fi everywhere.
Fact-check needed (Badrangui)
- [ ] Top 2–3 mobile providers foreigners most commonly buy (names)
- [ ] Typical tourist plan price range (rough: low/medium/high + MNT)
- [ ] Is eSIM realistically available for tourists in UB right now? (yes/no/depends)
