Japanese, Chinese and South Korean communications ministers agreed Monday to reduce international roaming fees.
High fees are an obstacle to increased use of such services, communications minister Seiko Noda said.
International roaming enables people to use their mobile phones outside their countries.
The three ministers, meeting in Tokyo, agreed to ask mobile phone carriers in their countries to lower international roaming fees.
They also agreed to cooperate on technology development and standardize frequency bands to launch fifth-generation, or 5G, mobile communications service as soon as possible.
