Will CoreESIM provide internet coverage on Tonga's outer island groups, such as Vava'u or Ha'apai?

CoreESIM leverages established local network infrastructure, typically connecting to carriers like Digicel or TCC, to offer coverage across Tonga. On the outer islands, users can expect robust 4G signal presence in main administrative centers, such as Neiafu (Vava'u) and the principal villages within the Ha'apai group. However, connectivity diminishes significantly when venturing into remote marine areas or less populated islets, where mobile network base stations are not deployed. For critical offshore activities, satellite communication remains the most reliable option.
