Thank you for your understanding.

We are pleased to announce that the IMEI Network Status Checker feature has been newly added to RE:FON, our B2B platform for pre-owned smartphones and tablets.

With this feature, users can simply enter an IMEI number to instantly check
the network usage status (○ / ▲ / × / –) of major mobile carriers directly on RE:FON.
This helps reduce risks during purchasing and selling, while improving transaction transparency.

In addition, this feature is available free of charge for all users, including the general public.
No account registration is required, and the tool offers a clean and easy-to-use interface for anyone to use comfortably.

We will continue to enhance RE:FON with functions that support safer and more efficient device transactions.
