  • Use it and then just throw it away.

    With this Japan SIM card we dare say you have by far the best data value for your travel to Japan compared to other SIM card options, MiFi rental and roaming. With MiFi rental, you need to pay a hefty deposit and return it once used. Not to mention the hassle of charging the MiFi unit with the limited powerpoints overseas. On the other hand, with this Japan Travel Prepaid Sim card, you can use it in your phone and throw it away after finished using it. Need not return it to us!

  • Use back your own social media accounts.

    Even though you are using a different Sim card, you can still have access to all your existing social media accounts like Whatsapp, Wechat and Line. Conveniently stay connected with your family members overseas at all times.

Typical Daily Data Usage Overseas

(Only for your reference. Different users will have different usage pattern)

My phone is region locked and can only accept South East Asia SIM cards. Can I still use this card in Japan?

The new Samsung phone models have a sticker showing “South East Asia SIM Cards only” in the packaging. The message simply means you need to use a South East Asia SIM card to activate the phone. After you made calls of at least 10 minutes with the phone, your phone will then be able to use any SIM cards worldwide.
