FAQ
What is the practical speed difference between sub-brands and MVNOs?
Sub-brands use their parent MNO's network directly, bypassing the capacity rental bottleneck that affects MVNOs. Speeds remain more stable during peak hours. For users who want low pricing without compromising on speed, sub-brands hold a clear advantage.
How do I choose between ahamo, povo, LINEMO, UQ mobile, and Y!mobile?
Ahamo, povo, and LINEMO are fully online services for tech-comfortable users. UQ mobile and Y!mobile maintain partial physical store support, better for users who want in-person help. UQ and Y!mobile also offer family and home bundle discounts.
Can I keep my existing smartphone when switching to a sub-brand?
In most cases, yes. Unlocked phones or phones from the same carrier group work without modification. Devices purchased in Japan after 2021 are sold SIM-unlocked by default, so this is rarely an obstacle.
