China Unicom said it activated an emergency base station 1.2 km from the Jilong
border crossing at 13:30 on Aug. 30. The new site fills a frontier
communications blind spot and is intended to provide stable connectivity for
on-site rescue, road clearance, supply transport and frontline personnel. China
Unicom enabled full-network emergency mode and 5G cross-network roaming to raise
coverage, stability and resilience in the border area. The operator said mobile
base stations will remain on standby, it will monitor road-clearance and
disaster progress, and will continue optimizing border network quality to shore
up emergency communications.
