CoreESIM plans are predominantly engineered as data-centric packages, providing robust internet connectivity. They typically do not include a dedicated local phone number for traditional circuit-switched voice calls or SMS messaging. However, the high-speed data provided by CoreESIM perfectly supports VoIP (Voice over IP) applications such as WhatsApp, FaceTime, Zoom, or Skype. These platforms enable you to make voice and video calls, and send instant messages, leveraging your data allowance effectively.
