It is important to manage expectations regarding CoreESIM connectivity in certain Himalayan regions of India. Due to specific government regulations, prepaid roaming SIMs, including CoreESIM, typically do not function in the Union Territories of Jammu & Kashmir (J&K) and Ladakh. While CoreESIM offers extensive coverage across approximately 99% of India, including major regions like Delhi, Goa, and the South, these particular areas are exceptions. Travelers to Ladakh or Kashmir should anticipate limited or no data service and plan accordingly.
