Two popular options for maintaining connectivity while traveling in Japan are eSIMS and Japanese pocket WiFi rentals. Both options have their own unique features and advantages, and understanding the differences between them is essential for making an informed decision. Here’s everything you need to know to make the best choice for your travel needs.

eSIM vs Pocket WiFi: What Exactly Are They?

If you’re not familiar with these devices, then let’s first define what they are and how they work. 

An eSIM is a term referring to “embedded SIM cards,” which are small, programmable chips that are integrated into mobile devices, unlike physical prepaid SIM cards where you have to insert and remove the SIM card whenever you need to making it one of the best Internet Options in Japan.

On the other hand, pocket WiFi is a portable WiFi router that connects to local cellular networks, providing internet access for multiple devices through a secure WiFi network. 

Both options offer distinct benefits and considerations, but comparing both devices and their features can help you decide which one will better impact the quality of your trip to Japan.

Comparing the Two: eSIM vs Pocket WiFi

The Cost and Price Range

The pricing structures for both options can vary based on factors such as data allowances, rental durations, and additional fees. Before figuring out which option is more cost-effective, it’s best to understand your traveling lifestyle such as how much WiFi you’ll be using, your duration in Japan, and how many devices need to be connected to the internet. 

Japanese pocket WiFi revolves around rental durations and data allowance. Meaning, it is not a one-time purchase so you’ll have to pay the rental fee again if you ever travel to Japan a second time around. Pocket WiFi rental companies typically offer daily, weekly, or monthly rental options, with discounted rates for longer rental periods. For daily rates, it can cost as around ¥600 (£3) for 3GB of data, while monthly rates can cost up to ¥6,600 (£33) for 5GB a day for 30 days. Take note that these prices do not include additional fees such as delivery charges, pickup fees, and security deposits. 

Meanwhile, eSIM providers typically offer a range of data plans tailored to different usage scenarios, such as internet browsing, social media usage, and heavy data consumption. Most Japan eSIM providers offer flexible pricing models, allowing travelers to top up their data plans as needed, thereby avoiding excessive charges for unused data. A weekly rate of an eSIM can cost as low as ¥800 (£4) or ¥1,400 (£7) depending on the plan. A monthly data plan can go as low as ¥2,500 (£12) for 30 days!

The Accessibility of Purchasing

One aspect to also consider when purchasing a device for travel WiFi is how accessible it is to find one and how easy it is to set it up. eSIMS and pocket WiFi rentals are very different when it comes to purchasing and setting them up making both of them one of the best Internet Options in Japan

Most pocket WiFi rentals in Japan can be purchased online, but since it is a physical device, it needs to be received through mail delivery or pickup at designated locations like an airport or the address of your hotel in Japan. After using it, you will need to deliver it back on a specific time and date to avoid extra fees. The setup process is straightforward with an instructions sheet usually provided in the box of the device or through the company’s website making it one of the best Internet Options in Japan.

Similarly, an eSIM can be bought online, but without the hassle of having it delivered or picked up. Once you’ve purchased an eSIM, you can already activate it on your phone by downloading a mobile app, selecting a data plan, and following the provider’s instructions to enable the eSIM on your mobile device. Since the eSIM is yours, there’s no need to worry about shipping it back to the provider.

  • Limited Device Connectivity
    • Although some eSIMs can provide hotspot networking for other devices to connect to, they cannot provide strong connectivity and coverage to multiple devices simultaneously. Therefore, eSIMs are not recommended for big traveling groups who need to connect to the same WiFi. 
  • Limited Device Compatibility
    • Since eSIMs are a new type of technology, not all devices are compatible with them. Not all smartphones and gadgets support eSIM functionality, so it’s important to check if your device is eSIM-compatible before buying one.

    • Since most pocket WiFi devices are rented, this means that there is an extra cost for rental fees and delivery charges. At the same time, pocket WiFi routers in general are more expensive. 
  • Extra Device 
    • Pocket WiFi is a physical router, which means that it is an extra device to your travel gear. It’s one more weight to carry, plus there is a risk of damaging or losing it, which may lead to more costs. 
  • Limited Battery Usage
    • Pocket WiFi devices need to be charged regularly, which means you need to bring a separate charging cord or batteries. This can be a hassle since it is an added responsibility keeping your pocket WiFi from running out of battery. 
  • Pick Up and Delivery Hassle
    • Upon purchasing or renting a pocket WiFi device, you cannot activate it immediately without the item itself, which must be picked up or delivered to your assigned address.
