Heads up!

Before we go into the process of application, there are a few things you might want to know beforehand.

Required Documents For Application

You need an ID (Residence Card, Insurance Card or My Number card). If you use the Residence Card or Insurance Card, you need supplementary documents (Certificate of Residency or paid electricity/water/gas bill) that have the same name, address and issued within 2 months. The Certificate of Residency cannot include your My Number on it, and the bills must show that they are paid (stamped). These documents are required for LINE mobile application.

Changing Carrier

If you are considering changing mobile carriers and keeping your original phone number, you need to obtain MNP number. You can get it from your current phone carrier. You can either call them or go onto their website and register for MNP number. There is a time limitation, and it is usually 15 days, you can only apply for LINE mobile within the first 5 days. So be careful! Don’t worry if you pass the MNP time period, all you have to do is re-apply.

Your device

If you are keeping your current phone, make sure it is SIM free. Meaning if you bought your phone through docomo, au or Softbank there are chances that the phone and SIM card is locked if so, all you have to do is go to your carrier and ask them to unlock it. If you are not sure, LINE mobile provided a list where you can look up your device and see if you need to unlock it or not.

Entry Package

LINE mobile provides an Entry Package, this entry package allows you to save some money. With the LINE mobile’s Entry Package, you don’t have to pay for the initial application fee (3,000 Yen). You can buy this on Amazon, Yodobashi, Biccamera, EDION, カメラのキタムラ (Camera no Kitamura), Joshin, Nojima (some stores might not sell them). The price is around 400 Yen.

There are risks to using entry package; you can only apply through the LINE mobile website, you can only apply to SMS included package, you might not be able to use the current campaign deals, your application might not work, and there is a time limitation on the entry package.

Unlimited free data

LINE mobile is open about the fact there are some fine prints of the SNS apps (LINE, Facebook, Twitter, and Instagram) unlimited free data usage. Most of the essential functions of these apps are data-free:


  • LINE > Phone calls + Messaging + Video/Image Sending + Timeline
  • Twitter > Timeline + Tweet + Tweet w/image + DM
  • Facebook > Timeline + Post w/image + Comment + Notification
  • Instagram > Timeline + Post + Activity + DM + Story Posting

On LINE mobile’s official website there is a list with pictures of what are considered data-free or not.
