Is DataESIM coverage reliable within the historic Old City of Jerusalem?

DataESIM offers generally strong outdoor coverage throughout the historic Old City of Jerusalem, including key sites like the Dome of the Rock and the Church of the Holy Sepulchre. However, due to the ancient, thick stone architecture prevalent in the Jewish Quarter, Christian Quarter, and subterranean areas, indoor signal penetration can be challenging. For optimal performance, users may find better reception closer to windows or in open-air sections of the Old City.
