Unlimited Japan 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 Japan 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

Troubleshooting Guide

eSIM not working? Don’t stress! Follow this guide to get you up and running.

  1. Disable VPN and any secondary SIM/eSIM lines (for dual SIM phones)
  2. Connect to Wi-Fi and disable airplane mode before scanning the eSIM
  3. Confirm mobile data is sourced from our eSIM (i.e. the correct eSIM profile is selected)
  4. Turn data roaming on (Android: select all network)
  5. Wait up to 10 minutes for activation to occur
  6. APN: cmhk | Username: [blank]  Password: [blank] (Android: select manually)

    I couldn’t access any data. The eSIM was selected and roaming was enabled and still nothing. I shut down and restarted the phone with the same configuration and was still unable to access any data

    This was such a great deal! The staff told me this product was brand new and I run out of data in the last 5 days of my trip. I was able to pay $19 for 5 days of unlimited data with no issues at all!

    Best of all, I got immediate responses from the customer service and got it set up pretty quickly. 100% recommend! 🙂
