Mongolia eSIM for Travel – Instant 4G/LTE Data
Instant mobile data in Mongolia from £4.99. No roaming charges. Keep your UK number. Activates the moment you land.
Mongolia trips spend days off-grid in the Gobi or Khövsgöl – eSIM at base camp is often the only way to update family back home. TripSIM provides an instant Mongolia eSIM with coverage on Mobicom, Unitel, Skytel, so you can land at Ulaanbaatar Chinggis Khaan (UBN) and be online before you reach the taxi rank. MIAT operates seasonal connections; UK roaming is expensive and patchy outside Ulaanbaatar. No physical SIM swap, no airport kiosks, no surprises on your next UK phone bill.

Mongolia eSIM FAQs
Does an eSIM work in Mongolia?
Yes — TripSIM eSIMs work across Mongolia on local 4G/5G networks (Mobicom, Unitel, Skytel). You activate before you fly and it connects automatically when you land.
Can I keep my UK number while using a Mongolia eSIM?
Yes. Your physical UK SIM stays active for calls, texts and WhatsApp. The TripSIM eSIM runs alongside it as a data-only line.
Is hotspot / tethering included?
Yes, every TripSIM plan supports personal hotspot.
When should I install the eSIM?
Install before you leave the UK while on WiFi. Activation only starts when you connect to a local network in Mongolia.
Is TripSIM cheaper than UK carrier roaming in Mongolia?
Almost always. UK carriers typically charge £8–£14 per MB on UK carriers in Mongolia. Save up to 94% vs UK roaming.
Will a TripSIM eSIM work across Mongolia?
Yes. TripSIM connects to Mobicom, Unitel, Skytel, which together cover Ulaanbaatar, Erdenet, Darkhan and most Mongolia travel destinations. Coverage in remote regions may be more limited – check the coverage map before travelling off the main routes.
How much data do I need for 7 days in Mongolia?
For typical UK-tourist use (maps, messaging, social, occasional video calls), 0.3–0.7 GB per day is a comfortable allowance. We recommend our mid-tier plans for shorter trips and unlimited for two-week stays.
Is the TripSIM Mongolia eSIM faster than buying a SIM at Ulaanbaatar airport?
Buying a local SIM in Mongolia usually means queueing at an arrivals kiosk, showing your passport, topping up in Mongolian Tögrög and configuring APN settings. A TripSIM eSIM is QR-activated before you fly and online the moment your phone connects to a Mongolia network.
Can I make voice calls or send SMS with a TripSIM Mongolia eSIM?
TripSIM is a data-only eSIM. Voice and SMS are not supported – but you can call and message over WhatsApp, FaceTime, Telegram and other internet-based apps as normal. For UK emergency services, your physical SIM remains the appropriate route.
Does the TripSIM Mongolia eSIM work alongside my UK SIM?
Yes. Dual-SIM phones (iPhone XS and later, most modern Androids) can run your UK number for calls/SMS and your TripSIM data plan in parallel. We recommend turning off mobile data on your UK SIM to avoid roaming charges.
