Looking for a cheap SIM card in Japan? For a long time, one of the biggest troubles one would have when coming to Japan was to get a Japanese mobile phone number. To get a bank account you would need a phone number, and to get a phone number you would need a bank account. It was a puzzle to be solved. Thankfully, times are changing.

It’s easy to get a Japanese mobile number in Japan with this cheap SIM card

DXHUB has just started a new service, JP SMART CALL, a SIM card that works in any SIM-free smartphone, and that can be purchased by credit card or by cash at a convenience store with only one required document: a valid Residence Card. That’s right. No need for a bank account and personal stamp. Everything can be done online, for your best convenience!

This service is offered by DXHUB, a low-cost, foreign-friendly mobile services provider. We are fans of them here at Guidable. You can find our previous articles about them here.

Today I will be reviewing their newest service, JP SMART CALL.

International phone calls and VoIP – trouble in Japan






Japan has been welcoming expats for a while already. There are many people from overseas living in Japan, that means many are missing their families that stayed in their home countries. Until the mid 00’s everyone would use international phone calls to talk to their loved ones at home. These phone calls were very expensive, and for those that didn’t have a phone at their places, the only option was to use public phones that were available for international phone calls. Unfortunately, they weren’t very common.

A group of friends from Brazil already living here at the beginning of 90’s told us that there were huge lines to use public phones on pay-day. With the advance of technology, internet connections became cheaper, and Skype was launched in 2003. This has made it easier for expats and international students from all over the world to communicate with their homes.

When VoIP became a standard tool, we could see people saying that they won’t have phone numbers anymore, that they would only use VoIP. Well, not in Japan.

The importance of having a phone number in Japan

A mobile phone number is important in Japan as it is necessary for opening a bank account, renting a place to live, purchasing tickets to events online, making phone calls to toll-free numbers, and this is just to list a few.

Recently, web services that request personal authenticity ask for a phone number so they can send you access codes by SMS.

As you can see, since a mobile phone number must be registered to an individual, it has become a powerful tool for identity identification.

Getting a mobile phone number in Japan

Our best advice is that you get a phone number as soon as you arrive in Japan.

Until recently, there were only 3 options of mobile communication providers, and all of them had, and still have, a contract period of 2 years.

That means if you purchase a SIM card from one of these companies, and want to cancel it before 2 years have passed, you have to pay a fee for breaking the contract.

Fortunately, the government created a law that authorized the utilization of MVNO in Japan. Thanks to this law we now have other options for mobile cellphone providers.

Even with other options, it is still common for foreigners to have trouble trying to get a phone or a SIM Card. First, most companies still have a contract period, which can be inconvenient for those who are not going to stay that long in Japan. Also, many will not accept your residence card as a proof of your residence in Japan, or will ask you to present a bank account, or will ask you a personal stamp. Getting a phone number in Japan can be really stressful.

But it is too fast to give up.
