Most CoreESIM profiles for Bangkok are primarily engineered for mobile data provision. They typically do not include native local voice call or SMS allowances. However, users can seamlessly utilize VoIP (Voice over Internet Protocol) applications such as WhatsApp, Line, or Messenger for both voice calls and text messaging. These applications leverage the CoreESIM's robust data connection, providing a cost-effective and functionally equivalent communication solution.
