FAQ
Will speeds drop when switching from a major carrier?
For everyday use — social media, streaming, web — the difference is rarely noticeable. However, MVNO carriers can slow down during peak hours. Consider sub-brands like ahamo, povo, or LINEMO for consistent speed at ¥2,000–¥3,000/month.
How long does the MNP transfer process take?
eSIM transfers can complete the same or next day. Physical SIM orders take 2–5 business days. The MNP transfer code is valid for 15 days. Your old SIM deactivates automatically once the new line activates.
Can I keep using LINE after switching to a budget SIM?
Yes, if you transfer your number via MNP, LINE continues working with phone number verification. Back up your chat history before switching. If you register a new number, you'll need to follow LINE's account transfer process.
