KDDI announces 3G network shutdown

Japanese phone carrier KDDI says it will cease offering its 3G network service at the end of March next year. The service is used primarily for its feature phones, which are the predecessors of smartphones.

The carrier released a statement on Monday explaining that the reason for the move is a continual decline in the number of network users. KDDI added that it will invest resources in improving its 4G network and its new ultra-high speed 5G network.

KDDI said it will allow 3G network users to upgrade to 4G- or 5G network-compatible phones free of charge. Six models of feature phones and smartphones are available.

The carrier is asking 3G users to upgrade their phones no later than March 31, 2022, as the network’s call and other services will be cancelled automatically as of April 1.

KDDI’s rivals have already decided to discontinue offering 3G communication. Softbank will end its service in January 2024 and NTT Docomo in March 2026. NHK
