When planning your trip from Singapore or Malaysia to Japan, staying connected is key to a smooth and enjoyable travel experience. Whether you’re navigating public transport in Tokyo, sharing stunning photos of cherry blossoms, or searching for authentic local cuisine, having reliable mobile data brings your adventure to life.
Singapore stands as a global connectivity hub with one of the world’s most advanced telecommunications infrastructures. When departing from this ultra-modern city-state, travelers benefit from exceptional preparation options with high-speed internet available throughout Changi Airport. The Gardens by the Bay with its futuristic Supertrees and the iconic Marina Bay Sands should not be missed before your departure. While in Singapore, avoid littering or jaywalking as these actions carry strict fines. Additionally, refrain from eating or drinking on public transportation, as this is prohibited and can result in penalties that might put a damper on your travel plans.
Malaysia offers travelers a blend of cutting-edge infrastructure in cities like Kuala Lumpur alongside more rural experiences in regions like Borneo. Mobile coverage is excellent in urban centers but can become spotty in remote areas. Before heading to Japan, consider visiting the Petronas Twin Towers and the historical streets of Melaka, a UNESCO World Heritage site. When traveling through Malaysia, avoid displaying excessive public affection, particularly in more conservative areas, and never point with your index finger as this is considered rude in Malaysian culture. Be cautious about discussing sensitive political topics, which could lead to uncomfortable situations with locals.
Japan combines ancient traditions with cutting-edge technology, creating a unique travel environment. The country boasts excellent telecommunications infrastructure with high-speed internet and reliable mobile coverage in most areas. Mount Fuji, the historic temples of Kyoto, and the vibrant districts of Tokyo such as Shibuya and Akihabara should feature on every traveler’s itinerary. However, avoid speaking loudly on phones while using public transportation, as the Japanese value quiet in shared spaces. Never enter a traditional onsen (hot spring bath) without showering first or while wearing swimwear, as this violates important cultural norms. Additionally, tipping is considered unnecessary and can even be perceived as insulting in restaurants and taxis.
Global eSIM offers a user-friendly solution with instant activation as soon as you land. No more waiting in lines or hunting for physical SIM cards at the airport.
You can activate your eSIM instantly and start using data right away to access maps, book rides, or translate signs effortlessly.
This is particularly valuable when arriving at busy international airports such as Narita, Haneda, Kansai, or New Chitose, where language barriers might otherwise make obtaining local connectivity challenging.
Another major advantage is flexibility.
Global eSIM plans come in various sizes, perfect for short city breaks or longer journeys across multiple Japanese regions. If you plan to visit neighboring countries like South Korea or China during your trip, our regional eSIM automatically switches carriers when crossing borders, ensuring you stay connected throughout your itinerary without swapping SIM cards.
Your mobile data opens up a world of convenience:
Planning a trip isn’t only about logistics-being able to enhance your experience with mobile data can truly enrich your journey.
Before departing Singapore for Japan, don’t miss the spectacular Gardens by the Bay with its iconic Supertree Grove and immersive Cloud Forest dome. The cultural enclaves of Chinatown, Little India, and Kampong Glam offer authentic local experiences with stunning architecture and culinary delights. For a final panoramic view of the city, head to the Marina Bay Sands SkyPark or take a nighttime ride on the Singapore Flyer to appreciate the city’s impressive skyline illuminated against the night sky.
Malaysia offers diverse experiences worth exploring before your Japan journey. In Kuala Lumpur, the Batu Caves with their colorful Hindu shrine and towering golden statue create an unforgettable cultural experience. The historical streets of Georgetown in Penang showcase stunning street art alongside colonial architecture and mouth-watering street food. Nature lovers should consider a quick visit to the Cameron Highlands for stunning tea plantations set against misty mountains or explore the crystal-clear waters of the Perhentian Islands for world-class snorkeling.
Once in Japan, prioritize visits to Kyoto’s historic district with its perfectly preserved temples, traditional wooden machiya houses, and the chance to spot authentic geisha in the Gion district. Tokyo’s diverse neighborhoods offer something for everyone-from the cutting-edge fashion of Harajuku to the electronic wonderland of Akihabara and the serene gardens of the Imperial Palace. Nature enthusiasts should make time for the perfect symmetry of Mount Fuji, the stunning autumn colors of Nikko, or the peaceful spiritual atmosphere of Miyajima Island with its “floating” torii gate.
In Singapore, avoid littering or jaywalking as these carry strict fines. Never bring durian fruit into public transportation or hotels due to its strong odor.
In Malaysia, avoid public displays of affection, particularly in conservative areas. Don’t point with your index finger or touch someone’s head as these gestures are considered disrespectful. Refrain from discussing sensitive political topics or criticizing local customs.
In Japan, never enter an onsen (hot spring bath) without showering first or while wearing swimwear. Avoid talking loudly on phones while on public transportation, as silence is valued in shared spaces. Don’t tip at restaurants or taxis as this can be perceived as insulting. Never pour your own drink in social settings-instead, pour for others and let them reciprocate. Finally, avoid walking while eating on public streets, as this is considered impolite.
While traveling, keep these essential emergency numbers handy in case of urgent situations:

Will my eSIM work on Japanese bullet trains (Shinkansen)?

Singapore offers excellent connectivity with widespread free public WiFi (Wireless@SG) throughout the city. Most cafes, shopping malls, and public spaces provide reliable internet access. Note that Singapore uses the British-style power socket (Type G), so bring an appropriate adapter for charging your devices before departure. When using public WiFi, consider activating a VPN for additional security, especially when accessing sensitive information.
Malaysia uses Type G (British) socket outlets, similar to Singapore. Major cities offer good 4G coverage, but rural areas may have limited connectivity. Public WiFi is available in shopping malls and cafes but may not be as widespread or reliable as in Singapore. Be aware that Malaysia has strict laws regarding online content, so exercise caution when posting on social media platforms. For local calls within Malaysia before your departure, be aware that you need to dial the full number including the area code even for local calls
.
Japan primarily uses Type A and B power outlets (similar to North America but at 100V), so an adapter may be necessary depending on your device. Free WiFi can be limited compared to other countries, making your Global eSIM particularly valuable. Many restaurants and cafes require registration or a password to access their WiFi. Japan offers excellent 5G and 4G coverage in urban areas and good coverage even in many rural regions. Consider downloading useful apps before arrival, including a reliable Japanese translation app, train navigation tools like Japan Transit Planner, and emergency notification apps like Safety tips, which provides disaster alerts in multiple languages.
