If you want to make a mobile phone contract in Japan, but you are wondering where to go, LINE MOBILE is one of the most recommended. LINE MOBILE is a communication service of cheap SIM and smartphone provided by communication app "LINE". Registration is completed online, so even foreigners who are not good at speaking Japanese can easily contract with it.

We recommend LINE MOBILE's data + SMS plan or data + SMS + voice-call plan because those plans do not set a minimum contract period. In the case of data + SMS + voice-call plan, you can cancell anytime as paying the cancellation fee of 1,000 yen, unlike major telecommunications carrirs: SoftBank, au, NTT docomo. It does not renew the contract automatically. You can save on comunication charges by subscribing to LINE MOBILE.

This feature article focuses on LINE Mobile, which allows foreigners to contract. It explains how to contract, the point of identify verification, documents required when making a contract, and the flow of the contract. In addition, we will introduce features, price plans, campaign information, and cancellation methods.

LINE MOBILE that Foreigners Can Contract

LINE MOBILEThe new contract has been discontinued on 31st, March

LINE MOBILE can be used anywhere in Japan as it uses the communication line of NTT DoCoMo, the largest telecommunications carrier in Japan. The biggest benefit is that you can use LINE, Facebook, Instagram, and Twitter without data limitation. The price plan is available from ¥ 660 a month that is the most reasonable plan called a data communication plan. There is no restriction on the contract period so it is especially recommended for foreigners.
Most common Japanese cheap SIMs and cheap smartphones are required to register for a credit card issued in Japan when making a contract. However, LINE MOBILE is available not only a credit card but also LINE Pay and LINE Pay cards. Therefore, even foreigners who do not have a credit card issued in Japan can contract.
