CoreESIM provides a significantly more efficient method for obtaining mobile data compared to purchasing a physical local SIM card at Sarajevo International Airport (SJJ). Local providers such as BH Telecom or HT Eronet typically require an in-person visit to a sales point, potential wait times, and a mandatory passport registration for prepaid SIM activation. CoreESIM is a fully digital solution, eliminating the need for physical interaction, queues, or any ID verification, ensuring immediate data access upon arrival.
