CoreESIM users in the UAE should be aware of local telecommunications regulations. The UAE government enforces specific restrictions on Voice over IP (VoIP) services, which includes blocking voice and video calls made through applications such as WhatsApp, FaceTime, Messenger, and Telegram. While text messaging and data services through these apps function normally, the call features are generally inaccessible. These restrictions apply regardless of the eSIM provider and are implemented at the national carrier level.
