Charges of LINEMO

In this section, we will look at the following items regarding LINEMO‘s charges.

Administration Fee¥0
Cancellation Fee¥0
Plans3GB:¥990 or 20GB:¥2,728/mo
Extra Gigas¥550/GB
Domestic Calls¥22/30 seconds
Unlimited Calls¥550* or ¥1,650/mo*unlimited 5-minute calls
Promotions990 yen worth of PayPay points for 6 months etc.

Let’s look at them in order.

Administration Fee

LINEMO offers no administrative fee; many services charge between 3,000 yen and nearly 4,000 yen, but LINEMO’s no fee makes it easy to sign up.

Cancellation Fee

LINEMO also has zero cancellation fees. There is no minimum usage period.


LINEMO offers the following two plans.

Monthly BilGB/moSpeed after Bandwidth Limit

Even if you run out of gigs, you can still use the internet at low speed. I was limited to 300 kbps, but I managed to watch YouTube.

Also, with both plans, you can use LINE text messages, voice calls, and video calls as much as you want at high speed.

So it is quite possible to get through a month with the 3GB/990yen plan.

Extra Gigas

If you run out of LINEMO gigs, you have the option of buying additional gigs, in addition to continuing to use it at a lower speed.

The cost is 550 yen for 1 gigabyte. It can be conveniently purchased online.

Domestic Calls

LINEMO’s domestic call charge is 22 yen/30 seconds. As mentioned earlier, both voice and video calls on LINE are completely free.

Unlimited Calls

LINEMO’s two unlimited calling options are as follows.

OptionMonthly Bill
5-minute unlimited calling¥550
Completely unlimited calls¥1,650

If you sign up for the 5-minute unlimited call plan, you can save money on calls by hanging up before the 5 minutes is up and calling back.


LINEMO is actively running promotions. The campaign that led me to sign up for LINEMO was a plan that offered 990 yen worth of PayPay points for 6 months, which can be used for shopping, dining, and paying LINEMO bills, making it a very good deal.

Additional information about the promotion
  • Not applicable for smartphone plans(20GB/¥2,728).
  • Not applicable if you are transferring from SoftBank, Y-Mobile, or LINE Mobile.
  • Cannot be used together with campaigns in which PayPay points are eligible.

LINEMO uses its own lines, so you can enjoy high speed internet anytime, anywhere. 5G has given me nearly 300Mbps at times. I was surprised that it was faster than WiFi at home.


LINEMO supports eSIM and there is no charge for eSIM issuance. I have a contract with eSIM.


LINEMO is already 5G compatible; if you are in a 5G compatible area with a 5G compatible phone, you can use high speed internet.


LINEMO bills can be paid in the following ways.

It helps that they support a variety of methods.

Change of Plan

LINEMO plan changes can be made online. By completing the procedure by 9:00 p.m. on the last day of each month, the plan switch will take effect the following month.


There is an app for the procedure to start using eSIM.

International Roaming

LINEMO can be used overseas for internet, calls, and SMS.
