What makes Mobal so special?

Having a Japanese SIM card makes staying in touch with friends and family—not to mention navigating Japan—a breeze. But how do you choose the card for you? Mobal makes it simple with both short-term and long-term SIM cards plans. With an easy ordering process, native English-speaking customer support, no contracts, and profits that go to charity, why would you pick anything else?

Renting a cell phone can be a hassle and trying to get a Japanese SIM card can also be a trial. If you don’t have a Japanese credit card or residence visa, most companies won’t even give you a chance. Even if they do, then you have long forms to fill out in Japanese, which can be a headache. That's where Mobal comes in to save the day. With their Japan Unlimited SIM Card plans, the obstacles between you and connectivity are gone – simply buy the card, activate it, and cancel when you're done.

Whether you’re on a short vacation or something a bit longer, Mobal has you covered with their variety of plans. The best part? You can get your SIM card shipped to you before you even leave for the airport—or you can pick it up from one of their easy-to-find pick-up points. Their multi-size SIM card takes the challenge and guesswork out of finding the right fit. Mobal’s SIM cards will work in any unlocked phone. With excellent coverage from Japan’s top networks—Softbank and Docomo—you’re sure to enjoy reliable service, great call quality, and ultra-fast data speeds.

Plan Overview

Speed, speed, speed! Mobal makes sure you get it. With Softbank’s reputation for fast speed and reliability, you’ll be cruising with the top tier. You could get speeds up to 187.5Mbps if you have a phone that supports 4G LTE. And with Mobal, you won’t be caught without data. If you go over your monthly allowance, your data speed is simply reduced to 128Kbps. That might not be enough to stream music or videos, but it’ll keep you connected to the internet for browsing, emailing, posting, and messaging.

Keep in mind that Mobal SIM cards work in any unlocked phone that supports 3G or 4G Band 1 frequency (2100MHz). An unlocked phone is one which works with a SIM card from any network. If your phone is locked, it’s restricted to work only with your carrier’s network. In this case, you may have to ask your provider about unlocking your phone, so that it can work with Mobal SIM cards.

Delivery or Pick Up

There are numerous options for receiving your SIM card once you’ve ordered. If you want to get the card in advance, enjoy free shipping to most major countries. This ensures that you have everything set up and ready before you even leave home. You can also pick your SIM card up in Japan at Mobal’s convenient pick-up points in airports and cities all around Japan. From Kyushu to Tokyo to Hokkaido and plenty more, the location options are numerous. The best part is that no matter what you choose, it’s free and easy.

New charges show up on the 1st of each month and it’s all itemized, so that you know exactly what you’re paying for. Mobal makes sure there are no hidden fees when you pay, and if it isn’t convenient for you to pay by debit/credit card or PayPal, you can even set up your account to pay in cash at any of the thousands of convenience stores around Japan.
