But with so many internet options available, it can be tricky to know whether Pocket Wi-Fi, a SIM card, or an eSIM is best for you. This guide breaks down the pros, cons, and real-world tips for each, so you can travel Japan with confidence—and a full signal.

📶 Option 1: Pocket Wi-Fi
A Pocket Wi-Fi is a small, portable device that lets you connect to the internet wherever you go in Japan. You can link multiple devices to it, making it popular with families, friend groups, or people traveling with laptops and tablets.
Read our dedicated blog on the best pocket wi-fi options.
✅ Why It’s Great
One of the best features of Pocket Wi-Fi is that it works for multiple people. If you’re traveling as a group or family, you can all share a single connection. Most services also offer unlimited or very high data limits, so you won’t have to worry about streaming videos, navigating Google Maps, or uploading photos. Another plus: you don’t have to swap out your phone’s SIM card or worry about phone compatibility—it works for any Wi-Fi-capable device.
❌ The Downsides
However, a Pocket Wi-Fi can be a bit inconvenient. First, it’s one more device to carry and charge throughout the day. If it runs out of battery, everyone relying on it loses access. Second, all users must stay within close range—typically 10 meters (around 30 feet). That means if someone in your group wanders off to a different shop or restroom, their connection may drop. Finally, you’ll need to pick it up (usually at the airport or via delivery) and return it before you leave Japan.
🔧 How to Make It Work Better
If you go with a Pocket Wi-Fi, be sure to bring a small power bank to keep it charged. Carrying it in a secure pouch or crossbody bag makes it easier to manage. Choose an airport pickup and drop-off plan for a smoother start and end to your trip. While it’s great for families, couples who tend to move independently throughout the day may want to consider separate SIMs or eSIMs.
📱 Option 2: Physical SIM Card
SIM cards are a familiar solution for many travelers. With a physical SIM card, you insert it into your unlocked phone, giving you access to a local mobile network while you’re in Japan.
✅ Why It’s Great
Using a SIM card is simple: insert it, restart your phone, and you’re good to go. You don’t need to carry any extra devices, and once set up, the connection is stable and fast. It’s ideal for solo travelers or anyone staying in Japan for a week or more. You’ll enjoy reliable coverage without having to worry about Wi-Fi hotspots or extra gadgets.
❌ The Downsides
There are a few catches. Your phone must be unlocked to accept a foreign SIM card. Some travelers—especially those from North America—may need to check with their carrier before departure. Also, the SIM will only work in one device. You won’t be able to share data with your partner or laptop unless you enable tethering, which some Japanese providers don’t support. Lastly, the setup may be confusing if you’re not comfortable with switching SIMs.
🔧 How to Make It Work Better
To avoid headaches, purchase your SIM from a trusted provider like Mobal, Sakura Mobile, or B-Mobile. These companies offer English support and clear instructions. Pack a SIM ejector tool or a small paperclip to help with the swap. If you’re unsure how it works, you can watch a short tutorial video before your trip. And always confirm that your phone is unlocked before you fly to Japan.
🌐 Option 3: eSIM
The newest and most seamless option for travelers is the eSIM—an embedded digital SIM that doesn’t require a physical card. With eSIM, you simply scan a QR code or activate a mobile plan through an app, and you’re connected.

✅ Why It’s Great
eSIMs are incredibly convenient. You don’t need to worry about finding a physical SIM card or waiting in line at the airport. Everything is done online—before or after you arrive. It’s also great for last-minute planners, people arriving late at night, or digital nomads who need a connection right away. Because there’s no extra device involved, it’s light, fast, and clean.
❌ The Downsides
The biggest limitation of eSIMs is that not all phones support them—especially older models. And while setup is usually easy, if something goes wrong, it can be difficult to troubleshoot without strong tech knowledge. Like physical SIMs, eSIMs typically only work for one device. Also, data packages for eSIMs may be slightly more expensive than physical SIMs if you need large amounts of data.
🔧 How to Make It Work Better
Before you buy, check that your phone is eSIM compatible (iPhones from XS onward usually are). Use reliable eSIM platforms like Airalo, Ubigi, or Nomad, which have strong user reviews and customer support. Make sure to download the app and QR code while you’re still on home Wi-Fi. If possible, activate the plan before you land so you can connect the moment you arrive.
📝 Which One Should You Choose? A Quick Comparison
To help you decide at a glance, here’s a breakdown comparing Pocket Wi-Fi, SIM cards, and eSIMs based on key travel concerns:
| Option | Best For | Shared Use | Extra Device? | Setup Difficulty | Airport Pickup Needed? | Average Cost |
|---|---|---|---|---|---|---|
| Pocket Wi-Fi | Families, small groups | ✅ Yes | ✅ Yes | ⭐ Easy | ✅ Usually | $4–8/day |
| SIM Card | Solo travelers | ❌ No | ❌ No | ⭐⭐ Moderate | ✅ Often | $15–40 total |
| eSIM | Tech-savvy users | ❌ No | ❌ No | ⭐⭐⭐ Easy (if compatible) | ❌ No | $5–25 total |
🧭 So, Which One Is Best for You?
Here’s a traveler-by-traveler recommendation based on typical needs and travel styles:
- 🧍 Solo travelers: A SIM or eSIM is the simplest, most convenient option.
- 👨👩👧👦 Families or small groups: Pocket Wi-Fi is best for shared data, but make sure you stay together and keep it charged. It will also be nice for parents to have their own SIM or eSIM. If they are all adults, SIM or eSIM would be definitely better options.
- 📵 Older devices or no eSIM support: Stick with a physical SIM—just be sure your phone is unlocked.
