What is the CoreESIM signal coverage like in Sri Lanka's central highlands and safari parks?

CoreESIM leverages primary network operators in Sri Lanka to ensure robust 4G/LTE connectivity across key tourist regions. In the central highlands, strong signal is typically available in developed areas such as Ella and Nuwara Eliya, supporting navigation and communication. For safari zones like Yala National Park or Udawalawe National Park, reliable data access is generally present at park entrances and within designated administrative areas, though coverage may diminish in remote interior sections due to natural terrain and infrastructure limitations.
