Travel guides

Vilnius, the beautiful capital of Lithuania, sits near the geographical centre of Europe, where nature blends seamlessly with modern life. The city welcomes adventurous travellers with colourful neighbourhoods and quiet, winding streets. It is famous for its churches and museums and for authentic Lithuanian cuisine.

Bali is Indonesia's most-loved island — clifftop temples, emerald rice terraces and world-class surf — and with a Bali eSIM installed before departure you are online the moment your plane touches down at Ngurah Rai. The island packs wildly different worlds into a small space: bohemian Canggu, spiritual Ubud, polished Seminyak and the raw limestone cliffs of Uluwatu. Add warung meals for a couple of dollars, a scooter-first way of life and one of the warmest cultures in Asia, and it is easy to see why so many travellers and digital nomads never quite manage to leave. If Bangkok is also on your route, see our [Bangkok travel guide](/travel-guide/bangkok).

Bangkok is Southeast Asia's most electric capital — golden temples beside glass towers, boat-filled canals and arguably the world's best street food — and with a Thailand eSIM installed before you fly, you are online the second you land. Give the City of Angels three days and it will still leave you wanting more: sunrise temple visits in the Old City, rooftop sunsets over the Chao Phraya and midnight noodles in Chinatown. If Singapore is also on your route, see our [Singapore travel guide](/travel-guide/singapore).

Barcelona, the sun-drenched capital of Catalonia, is a city best explored connected — with a Barcelona eSIM installed before you fly, you step off the plane ready to navigate Gaudí's fantastical facades, medieval lanes and beachside promenades without hunting for Wi-Fi. Few cities pack so much into so walkable a space: world-famous Modernista architecture, a Gothic core more than two thousand years old, Mediterranean beaches inside the city limits, and one of Europe's greatest food scenes, from market counters to old vermouth bars. If Paris is also on your route, see our [Paris travel guide](/travel-guide/paris).

Dubai is a city built on superlatives — and one where a working eSIM matters from the first minute, because everything from taxis to restaurant menus runs through apps. The city stacks the world's tallest tower, artificial islands and century-old gold souks alongside a food scene fed by two hundred nationalities. Between the air-conditioned mega-malls and the old creekside quarters, Dubai rewards travellers who plan around the heat, ride the metro and keep their phone online. If Istanbul is also on your route, see our [Istanbul travel guide](/travel-guide/istanbul).

Istanbul is the only megacity that spans two continents, and with an eSIM installed before you land you are online the moment you cross between Europe and Asia. Byzantine domes, Ottoman palaces, ferry horns on the Bosphorus and some of the world's best street food make this a city you can visit ten times and never finish. This guide covers the sights, neighbourhoods, fares and connectivity tips you need for a smooth first trip. If Dubai is also on your route, see our [Dubai travel guide](/travel-guide/dubai).

New York never slows down, and neither should your connection — install a New York eSIM before you fly, and your maps, subway app and ride-hailing work the second you land at JFK. The city packs world-class museums, Broadway theatres, skyline icons and five boroughs of food into a street grid that is surprisingly easy to navigate. Give it at least four or five days: between Central Park mornings, Brooklyn afternoons and Midtown nights, every extra hour here pays off. If Tokyo is also on your route, see our [Tokyo travel guide](/travel-guide/tokyo).

Paris rewards travellers who land prepared — timed museum tickets booked, a métro app ready and a Paris eSIM already installed, so data works the moment you step off the plane at CDG or Orly. The City of Light squeezes world-class museums, village-like hilltop quarters and legendary food into a compact core stitched together by one of Europe's densest metro networks. Give it four days at the very least; you will still leave planning the return trip. If Rome is also on your route, see our [Rome travel guide](/travel-guide/rome).

Rome, the Eternal City, layers close to three thousand years of history into one walkable capital — and with a Rome eSIM installed before you land, you can navigate its cobbled lanes, book Colosseum tickets and hop over to the Vatican without hunting for Wi-Fi. Ancient ruins sit beside Baroque fountains, trattorias spill onto piazzas, and every district rewards slow, curious wandering. If Paris is also on your route, see our [Paris travel guide](/travel-guide/paris).

Singapore squeezes futuristic gardens, heritage shophouse streets and arguably the world's best street food onto one compact island — and with a Singapore eSIM installed before departure, you're online the second your plane touches down at Changi. English is spoken everywhere, transport is spotless and everything runs on time, which makes this the easiest city in Asia for a first visit. Give it three or four days and it will still surprise you on the last one. If Bangkok is also on your route, see our [Bangkok travel guide](/travel-guide/bangkok).

Tokyo is the world's largest metropolis, and a Tokyo eSIM keeps you online from the moment you land — for live maps in the metro maze, translation apps at menu-only ramen counters, and finding that tiny bar hidden down an unmarked alley. The city layers neon canyons over Edo-period temples, and every neighbourhood feels like a separate city: electric Shibuya, old-town Asakusa, polished Ginza. Trains run to the second, dinner ranges from a ¥300 onigiri to one of the world's densest clusters of Michelin stars, and it all works with a calm, quiet order that surprises first-time visitors.
