8 things that everyone is curious about

What is SIM lock?

This is a system that restricts the use of SIM cards other than those of the mobile phone company you have a contract with.

  • There are two types of smartphones: SIM-free smartphones, which can be used with any SIM company, and SIM-locked smartphones, which are locked so that they can only be used with the SIM company from which they were purchased.
  • If you want to use a SIM card from another company on a locked smartphone, you will need to go through the "SIM unlock" process with the company you purchased the smartphone from.

How to unlock the SIM

Can I transfer my SNS data?

You can continue to use social media such as Instagram, Twitter, and LINE!

Is there a warranty if my phone breaks?

We offer a guarantee to give you peace of mind in the unlikely event of an emergency.

  • If your SIM-free smartphone is damaged or malfunctions, we offer the "Fault Protection Pack Premium" (880 yen per month). You can rest assured in case of an emergency.

Designated models and fees

Can I still use my phone number?

You can keep your current phone number.

  • We support MNP (Mobile Number Portability), so you can keep your current phone number.
