    Sometimes, finding free WiFi on your Japan trip can be tough. I think most of us have been in a similar situation before, arriving at the airport only to find we can’t access important travel docs by email or order an Uber because there's no internet.

    And this often means that we’re forced to pay roaming charges. Although many Australian telco providers only charge up to AUD 5 per day for this service, the cost can quickly add up if you’re in Japan for a two-week period, as this works out at AUD 70 per device.
    Imagine if you are bringing a family of four with a mobile each, that’s almost AUD 300 just for internet access!
    So, what should you do?

    Which one is better, a SIM card or a pocket WiFi?

    Opting for a pocket WiFi or a SIM card during your stay makes your travel experience in Japan easier. It basically simplifies everything, from exploring the best local sushi spots to booking tours and attractions or just finding your way back to the hotel hassle-free.
    Not only are pocket WiFi and SIM cards more budget-friendly than expensive roaming charges, but they also help you connect your Klook app without any buffering! This means you can explore and discover activities across Japan effortlessly.

    Individuals aged 18 and above visiting Japan have the option to purchase a local Japanese SIM card. However, there are specific limitations. Foreign visitors entering Japan are limited to using data-only SIM cards, and they are required to register their passports in accordance with Japan's SIM card registration regulations.

    2. What are the options for SIM cards in Japan?

    Since Japan is one of the top tourist destinations in the world every year, there are plenty of SIM card options available for tourists. The most widely used are Mobal and SoftBank, as they are easily accessible to travellers, and offer English support services for foreigners. This is the most important thing to consider when travelling in a non-English-speaking country.
    For detailed information on registration requirements, you can refer to the respective carrier's website.

    3. Where can I easily purchase data for the Japan travel SIM card?

    If you prefer a SIM card over a pocket WiFi, you can get one on Klook. These SIM cards offer fast and efficient service from Japan's primary mobile operator, enabling internet connectivity across Japan upon your arrival.
    You can choose from prepaid SIM card packages with unlimited data valid for 8 to 31 days.

    However, it's important to note that these SIM cards are specifically for data and do not include call or text services. If you need to use a voice-calling service, you are advised to get your 4G SIM card at the airport and register it manually with the help of the staff at the counter.
    Please note that these apps require a live local number to work: PayPay, Mobile Suica, Uber Eats, Wolt, Mercari, and Yahoo! Japan.

    The best part is? An eSIM card lets you access the Internet without removing your old SIM card. So, you don't have to worry about missing your local SIM card!

    A Portable WiFi in Japan

    1. How to get portable WiFi in Japan?

    Other than a 4G SIM card, you can opt for a portable wifi device (also known as pocket wifi) instead. You can use the Internet during your trip to Japan using this device which allows you to pay per day basis for WiFi rental. You’ll find the Portable 4G WiFi Plan convenient as it’s packed with unlimited data and can connect 5 devices max.

    Simply present your voucher at the Airport Service Counter in your airport of choice to receive your device (depending on the option you choose, some devices will require a refundable deposit to be paid).

    Which one is the best choice for my travel to Japan?

    Well, it depends on your usage, preferences, your stay location, and duration.

    4G SIM Card

    Portable WiFi Device

    Advantages

    Convenient: Easily fits into your phone.

    Portable: No additional device to carry.

    Flexible: Can add-on voice-calling or additional data.

    Shareable: Connect multiple devices.

    Extended Battery Life: Doesn't drain your phone's battery.

    Wide Coverage: Generally has good signal strength.

    Considerations

    Limited to your phone's connectivity.

    May not be shareable with other devices.

    Need to carry the pocket WiFi device.

    May have a rental fee or need to place a deposit.

    In other words, if you are travelling in a group and are concerned about your phone's battery, the packet wifi should be the nice pick. You can share the data with up to 5 people, but it also means that all of your friends need to stick together!
    If you are traveling solo and require a voice-calling, a 4G SIM card is the way to go.
