Unlimited South Korea Max Product Line

  • At TravelKon, we believe in clear and honest communication. Some sellers advertise ‘unlimited data‘ loosely. If you encounter ambiguous language about potential data slowdowns due to factors beyond their control and assurances that speeds will normalise the next day, it indicates undisclosed daily usage caps. Reducing the speed to 128Kbps without disclosure is misleading and barely enough for basic messaging!
  • Our Unlimited South Korea Max plan truly means unlimited at 20Mbps – sufficient for Google maps, fast browsing, email, social media and 4K video streaming.
