Are applications such as WhatsApp, FaceTime, or social media platforms like Facebook and Instagram subject to blocking in Pakistan with CoreESIM?

No, CoreESIM users in Pakistan will find that common communication and social media applications, including WhatsApp (voice and video calls), FaceTime, Google Maps, and Facebook/Instagram, are generally accessible. Unlike certain other countries, Pakistan does not implement a pervasive 'Great Firewall.' However, it's important to note that the government has historically exercised the ability to temporarily suspend mobile data services across specific regions during times of civil unrest or national security concerns.
