Unlimited 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 Max plan truly means unlimited at 10Mbps – sufficient for Google maps, browsing, email, social media and video streaming.
    • For example, downloading files for one hour at 10Mbps uses approximately 4.4GB of data

Fantastic

Although it took me a few attempts to make the network connection when entering South Korea, I had it sorted by the time I left the airport. As a first time eSIM user I loved the comprehensive instructions with the use of screenshots. A great experience all round

Easy setup, had quite a number of drop outs while in Seoul but worked again once I turned it off and on. Great connection when it works.
