Frequently Asked Questions

Does ZenSim offer unlimited data eSIM for Japan?

ZenSim does not provide a true unlimited highโ€‘speed data eSIM for Japan. The plans marketed as โ€œJapan Unlimited STANDARDโ€ supply a daily limit of 3GB and therefore are not unlimited; after that limit is reached, the connection speed is throttled, though the exact reduced speed is not listed.

If a traveler needs a larger data allowance, ZenSim offers fixedโ€‘data plans such as the Japanโ€ฏ20GB plan, available for 10 days or 30 days, and the Japanโ€ฏ10GB plan valid for 30 days. These plans give a fixed amount of highโ€‘speed data and can be more cost effective for moderate to heavy data use. ZenSim does not currently offer a truly unlimited data eSIM covering Japan.

Does ZenSim offer Japan eSIM with phone number and SMS?

ZenSim does not provide any eSIM plans for Japan that include a phone number or SMS capability. Only dataโ€‘only eSIMs are offered. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection instead.

How many data plans does ZenSim offer for Japan?

ZenSim provides 8 singleโ€‘country plans specifically for Japan, along with 8 multiโ€‘country plans that include Japan as part of a broader regional offering. The plans span a price range of $13.00 to $70.00 and offer data caps from 3โ€ฏGB up to 20โ€ฏGB. Among these, 4 plans feature a daily data cap that resets each day, while 12 plans provide a fixed data amount for the full validity period. Tethering is allowed on the relevant plans.
