SK Telecom will launch a priority transmission service from June 10 to help firefighters respond quickly at disaster sites with stable communications. The service is designed to minimise delays in firefighters’ voice and data connections when network traffic surges in a specific area due to earthquakes, fires, large crowds or multiple accidents. It grants top access rights to pre-certified National Fire Agency corporate lines and will operate alongside the government-led PS-LTE network.

LG Uplus said on Tuesday it launched a priority network access service for firefighters to reduce disruptions caused by network congestion during disaster response. The service is designed to keep firefighters\' calls and data use more stable when mobile traffic spikes during major fires or accidents. The company said it follows an agreement signed with the National Fire Agency in October and a joint build-out by the three mobile carriers. It has begun replacing SIM cards starting in Changwon.
