Monthly fees are something people look at often.
But “fees” other than the monthly charge are easy to overlook.
When you sign up, when you cancel, when you reissue a SIM, when you change the payment method. How much does each one cost?
I’ll summarize what was written on Rakuten Mobile’s official pages (checked on October 13, 2026).
Bottom line
- The contract processing fee is 0 yen up to the 4th cumulative line under the same name. From the 5th line on, it is 3,850 yen (tax included) per line (from November 19, 2025)
- This “cumulative” count is all lines contracted since April 8, 2020. It includes lines that have been canceled
- The cancellation processing fee is 0 yen after one year from the start. Within one year, it is up to 1,078 to 1,100 yen (tax included), depending on the plan
- Exchanging or reissuing an eSIM is 0 yen. Exchanging or reissuing a SIM card is 3,300 yen (tax included)
- Fees are not eligible for Rakuten Points
Contract processing fee
| Condition | Amount |
|---|---|
| Up to the 4th cumulative line under the same name | 0 yen |
| When contracting a cumulative 5th line or more under the same name | 3,500 yen per line (3,850 yen tax included) |
- Applies from: November 19, 2025
- The amount is finalized in the second month after activation
How “cumulative” is counted
This is the point most easily overlooked.
The official page says the following.
- The total of all lines contracted since April 8, 2020 (the date full-scale service began)
- Includes lines that have been canceled
In other words, it is not “how many lines you have now.” It is the cumulative total of lines contracted in the past.
If you add lines for family, or if there are lines you contracted long ago and canceled, the cumulative count may have gone up without you noticing.
What is not written
- The definition of “same name” and how it is determined (such as the handling after a name change)
- Differences in fees between shops and online
- The handling of fees when porting in via MNP, and the contract processing fee when changing plans
- Conditions for reductions or waivers
To find out what your own cumulative count is, checking the official guidance or the page for contract holders is the sure way.
Cancellation processing fee
| Condition | Amount |
|---|---|
| After one year from the start | 0 yen |
| Within one year (Rakuten Saikyo Plan series) | Up to 980 yen (1,078 yen tax included) |
| Within one year (Rakuten Saikyo U-NEXT) | 1,000 yen (1,100 yen tax included) |
- May differ depending on discounts or programs
- Cases with unavoidable circumstances, such as cancellation of the initial contract or transfer/succession, are excluded
- When you change plans, the one-year determination starts from the usage start date of the line before the change
It is enough to remember “if you cancel within one year, a fee applies.”
Costs related to SIM/eSIM, MNP and numbers
| Item | Amount |
|---|---|
| eSIM exchange/reissue | 0 yen |
| SIM card exchange/reissue | 3,000 yen (3,300 yen tax included) |
| MNP porting-out fee | 0 yen |
| Choose-your-number service | 1,000 yen (1,100 yen tax included) |
If you lose or break a SIM, a physical SIM costs 3,300 yen, while an eSIM is 0 yen. This is where a difference arises. For eSIM, there is the guide to eSIM on Android.
Costs related to name
| Item | Amount |
|---|---|
| Surname change | 0 yen |
| Transfer between family members or to a third party | 0 yen |
| Transfer between family members or to a third party (only when mailing documents) | 3,000 yen (3,300 yen tax included) |
| Succession | 3,000 yen (3,300 yen tax included) |
Costs for payment methods and delivery
| Item | Amount |
|---|---|
| Bank account transfer | 100 yen per month (110 yen tax included) |
| Barcode payment with Rakuten Pay | 110 / 220 / 440 yen tax included |
| Issuing a convenience store payment slip | 360 yen (396 yen tax included) |
| Shipping | 819 yen (900 yen tax included) |
| Document mailing service | 300 yen (330 yen tax included) |
- Bank account transfer costs 110 yen (tax included) per month. Easy to overlook compared with credit card payment
- Cash on delivery is 330 to 1,100 yen (tax included), depending on the total value of the goods. It cannot be used for amounts of 300,001 yen or more tax included
- The fee for issuing a convenience store payment slip applies only when an invoice for service suspension or contract termination notice is issued. It is added for each unpaid month
- Shipping applies only when you purchase accessories alone
How to sign up without a credit card is summarized in this article.
Fees are “not eligible for point earning”
The official page says the various fees are not eligible for Rakuten Points.
Please don’t expect “points on fees.” The mechanism of points is also sorted out in the article on conditions for paying with points.
