"Create a visually striking Facebook ad poster for a mobile company, emphasizing their affordable call rates. Use orange as the primary brand color, blending it with white and light black tones for a sleek and professional appearance. Feature a bold headline that reads, 'Stay Connected for Less!' in large, modern typography at the top center. The design should include an abstract wave pattern in shades of orange as a background, symbolizing seamless connectivity. Incorporate an image of a modern smartphone displaying a call screen, surrounded by glowing connection lines or signal icons to represent communication. Include a smiling person in the foreground, appearing engaged in a phone conversation, to convey trust and satisfaction. The CTA, 'Switch to Low-Cost Calls Now,' should be placed prominently in an orange button with rounded edges near the bottom, paired with a subtle arrow icon to encourage action. Allocate a small area for the company logo in the top-right corner and a footer section for disclaimers or additional details. Optimize the poster for Facebook’s 1200x1200 pixel format, ensuring sharp visuals and proper alignment of all elements for maximum impact."
