Nothing kills the start of a trip like landing with no data — no maps, no ride app, no way to reach your hotel. 3JN Travel OS bundles a travel eSIM into your trip so you land connected, with no roaming bill and no SIM-kiosk queue.
Part of the same package
Add the eSIM when you plan the trip — it's provisioned for your destination and ready to activate before you fly. One package, one price, payable monthly.
Everywhere you're going
Data plans cover the destinations travellers actually head to — city breaks and long-haul alike.

How 3JN Travel OS handles your trip
Instead of juggling a dozen tabs, you describe your trip in one sentence and the AI turns it into a complete, bookable package — flights, hotel, airport transfers, a visa check and an eSIM — with every fee shown before you pay, never a surprise at checkout.
One protected ticket, not a risky gamble. Where your route connects, we book it as a single protected itinerary: your bags are checked through and, if a delay breaks a connection, the airline rebooks you at no extra fare. That is the real difference between us and the rock-bottom "self-transfer" fares elsewhere, where a missed leg means buying another ticket.
Pay your way. Pay in full, or put down a deposit and spread the rest over monthly instalments — a real airline e-ticket is issued the moment it is paid, and your price is locked from day one. A 24/7 price guard keeps watching your fare after you book and passes any saving back.
Sorted before you fly. Need a visa? VisaOS checks your eligibility and prepares the real, cancellable flight & hotel reservations an embassy asks for — the embassy makes the decision. Landing somewhere new? Your eSIM works the moment you arrive. Browse ready-to-book deals or start from the destination marketplace, and see how it all works.
What's included when you book your trip
- Real airline e-tickets — issued with a booking reference (PNR), valid at check-in; never a dead-end "book on the supplier's site" link.
- One transparent price — flights, hotel, baggage, transfers and taxes shown before you pay; you only ever pay a confirmed, bookable amount, not an estimate.
- Pay in full or monthly — a deposit holds it, instalments cover the rest, and your price is locked from day one.
- Protected connections — one ticket, bags checked through, free rebooking if a delay breaks a leg.
- Secure payments — cards handled by Stripe; 3JN never stores your card details.
The fastest way to see how it compares is to try it: describe your trip in one sentence and get a live, all-in quote in about a minute — then decide.

FAQ
What is a travel eSIM?
A digital SIM you activate on your phone to get local mobile data abroad — no physical SIM, no roaming charges. 3JN provisions one for your destination as part of your trip.
Do I need to buy the eSIM separately?
No — add it to your 3JN trip and it's part of the same package and the same pay-monthly plan.
