CoreESIM users in Saudi Arabia will find that major Voice over IP (VoIP) applications, including WhatsApp and FaceTime, now largely perform reliably over mobile data. Historically, there were significant restrictions on these services; however, these have been substantially eased. While minor, localized intermittent issues might occur, general usage for voice and video calls is permitted. CoreESIM leverages the robust 4G/LTE and 5G networks of carriers like STC, Mobily, and Zain Saudi Arabia, providing the necessary bandwidth for these applications in cities such as Riyadh, Jeddah, and Dammam.
