FAQ
How slow does an MVNO connection get during peak hours?
This varies by provider, but during weekday lunch hours (12–1pm), download speeds on many plans can drop to 1–5Mbps. Regular voice calls, messaging, and social media remain functional, but high-definition video may buffer. Major MVNOs like IIJmio and mineo publish regular speed test data.
Is APN configuration difficult when setting up an MVNO SIM?
Most MVNOs provide step-by-step guides for both iOS and Android. On iOS, installing a carrier profile typically completes the configuration. On Android, entering a few fields in network settings is all that is needed. Choosing eSIM often eliminates manual APN setup entirely.
Which carrier networks do MVNOs use in Japan?
Japanese MVNOs lease capacity from Docomo, au (KDDI), and/or SoftBank. IIJmio offers both Docomo and au options. Mineo supports all three networks. Choosing an MVNO on the same network as your current carrier simplifies device compatibility.
