Planning a trip to this beautiful country for work or leisure? It’s important to stay connected during the entire trip, of course! And to enjoy all the advantages of local service, the best option is a local SIM that can be inserted into the phone to speak like a local, with no tricks or hidden charges.
Travelers’ and business visitors’ needs are now covered
No matter the kind of trip, obtaining online traffic is crucial, since this allows solving many practical tasks: look up geolocation, addresses, routes and transportation, order taxis and hotels, translate road signs, notices & names (which will be extremely useful if a person doesn’t know Japanese), as well as send and receive emails, including very important correspondence related to the trip.
Options available
For visitors in modern days, 3 options are accessible:
A common and convenient choice is a physical Mobal card, which can simply be inserted into the phone. If the phone supports more than one SIM at the same time, this will be the best ever choice.
What is a Japanese SIM?
It allows users to stay connected the entire time while in Japan: to the Internet, voice & texts.
Prepaid/postpaid options
For a short-term tourist (days/weeks/a month), the best choice is a prepaid plan that clearly specifies the number of gigabytes of Internet, SMS & voice minutes in local networks available. Postpaid plans may be the best option for those foreigners who come to Japan on a long-term work contract, for businesspeople, students & other categories of visitors who plan to stay in Japan for months/years. Such mobile plans require signing a contract, proof of a local residential address & sometimes a bank account.
Benefits of using a local number
With a Mobal offer, users will have no restrictions—they can use all mobile services like a resident, at the same price:
There will be a real (not virtual) number, which means any local resident can call & the user can enjoy the Internet in Japan at the standard rates of mobile operators. No more roaming!

Purchase online before arrival
It’s best to order the service before flying to Japan. To save time & for greater convenience, it’s feasible to order delivery of a physical card to one’s address in one’s home country (if this service is available in the given country).
Pick-up at the airport or get the delivery to the hotel
Another convenient option is the ability to pick up an ordered card at a pick-up point at the airport upon arrival in the country. Or, if a person is heading directly to their hotel, it can be delivered straight to their hotel room.
Japan Mobal options
A Japan SIM card gives options with data (up to 30 GB/month), without data (only 500 MB) & without voice, data-only. In addition, each of the data plans can have different data sizes, from 1 GB and up, depending on personal needs.

Data allowance and speed
To choose the best plan of the prepaid SIM Japan, check the statistics of data sent and received on the phone. Mobile traffic data is stored in the settings in the information section, where it’s possible to see statistics accumulated over the entire time the current device has been used. Also, if a user plans to use their phone to set up Wi-Fi sharing for other devices connected to it (laptop or tablet), then that traffic must be taken into account as well.
Validity period and top-ups
All travel SIM Japan options offered are contract-free and prepaid. At the same time, a user can top up their balance and keep using the card after the billing period (1 month) ends. When topping up, users don’t pay again for the card itself, since that payment is made only once.
Device compatibility
Before starting to use a Japanese phone card, one has to make sure their device supports it. For this, the device must be unlocked (that is, able to connect to other carriers and their cards, not locked to one provider). It must also support a physical SIM (some phone models only support eSIMs). And it must be ready to work in mobile data Japan 4G networks.
Troubleshooting common issues
A user may encounter a number of potential problems when connecting to a Japanese number. Here’s how to solve the most common ones:
Remove the card and reinsert it. Also, try restarting the phone.
Enable mobile service and check the APN settings on the phone (provided by the carrier). Make sure automatic network selection is enabled in the Mobal SIM Japan settings. Also, try restarting the phone.
Check if automatic network selection is enabled on the phone. The user may need to enable 4G support manually in the settings.
When in Japan, there’s no reason to go without mobile service and Internet if there are so many great options available, especially those offered by Mobal. Staying connected in Japan is easier than it seems. And it’s very cost-effective if using the high-quality, well-designed plans from Mobal.
