Unlimited Japan KDDI Ultra 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 KDDI Ultra plan truly means unlimited data with no daily data caps!
- Ranked #1 by Opensignal in October 2024, KDDI leads Japan’s telecom market, surpassing NTT Docomo and Softbank. Known for its extensive coverage in both urban and rural areas, KDDI offers unmatched network performance, ensuring seamless connectivity across Japan’s diverse landscapes.
