Planning a trip to Japan and worried about staying connected and accessing the internet anywhere, anytime? How should you handle internet access in Japan? Should you choose a portable WiFi device, or go with the increasingly popular eSIM and Japan SIM cards? How do you select the right internet solution for your needs? This article will help you find the best internet solution. Whether it's your first time planning a trip abroad or you're a seasoned traveler, you'll find options here to meet your needs.
Why are more people choosing eSIM and Japan SIM cards when traveling to Japan?
With technological advancements, more travelers are ditching traditional portable WiFi devices in favor of more convenient and efficient eSIMs and SIM cards.
Here are the main reasons for choosing eSIMs and SIM cards:
Convenience
With an eSIM, simply purchase it online before departure and download it to your phone upon arrival in Japan; a SIM card can be purchased in advance and inserted into your phone upon arrival to access the internet.
When using an eSIM, you can even keep your home country's SIM card, making it easy to receive calls or reply to messages without losing any contacts.
Stability and Speed
eSIMs and SIM cards typically provide single-user access to local network services, ensuring stable signal and fast internet speed, unaffected by multiple users.
Transparent Costs
Compared to the rental fees of portable WiFi devices, the prices of eSIMs and SIM cards are more transparent, with no deposits or hidden fees.
Generally, Japan's eSIMs and SIM cards are sold, not rented, which means no returns are necessary and there are no worries about equipment loss or damage fees.
No Extra Equipment Needed
Using an eSIM or a Japan SIM card means you don't need to carry and charge a portable WiFi device; you can just use your phone to access the internet.
This lightens your luggage and reduces the burden during your trip.
