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.
The 5G technology will allow data transmissions much faster than the current fourth-generation telecommunications, an advantage that can be used in a wide range of fields, including security and telemedicine.
The communications ministers from Japan, China and South Korea last met in 2011. Monday’s meeting was chaired by Noda.
