What is the coverage profile for CoreESIM data outside Port Moresby in PNG?

When evaluating CoreESIM connectivity in Papua New Guinea beyond Port Moresby, it is crucial to understand the network topology. Reliable 4G/LTE service is predominantly concentrated in urban centers like Port Moresby and Lae. Areas such as the Kokoda Trail or the remote Highlands experience significantly diminished or entirely absent cellular coverage due to challenging geographical conditions and sparse infrastructure. CoreESIM leverages carrier networks where signal penetration is viable, but users venturing into deeply rural or mountainous regions should anticipate intermittent or no data service.
