CoreESIM provides reliable 4G/LTE coverage in Pakistan's major urban centers like Lahore, Karachi, and Islamabad. However, users should manage expectations for the high-altitude northern areas, including Gilgit-Baltistan (Hunza, Skardu). While some connectivity exists in populated valleys, the mountainous terrain inherently limits network infrastructure. Coverage in these remote regions will be intermittent or non-existent, particularly in very isolated areas or high passes. Plan accordingly for offline access.
