FAQ
Can I cancel a no-contract plan at any time? Are there any fees?
Yes, no-contract plans allow cancellation at any time without an early termination fee. Japan's 2019 telecom law prohibits cancellation fees exceeding ¥1,000. Some carriers still charge a small MNP transfer fee. Check exact terms on the carrier's website.
How often do budget SIM plans change?
The Japanese MVNO market is competitive, with major carriers revising plans roughly every six to twelve months. Being on a no-contract plan means you can immediately switch to a better deal as one appears.
Is the MNP number transfer process complicated?
MNP has been simplified significantly. Obtain a transfer code from your current carrier, then enter it during the new sign-up. The process takes 30–60 minutes. With eSIM, no physical mailing is required.
