Possible ThrottlingFrequently Asked Questions
Does eSIM Cards offer unlimited data eSIM for Japan?
eSIM Cards does not sell a truly unlimited data eSIM for Japan.
All of its so‑called “Japan Unlimited eSIM” plans provide a fixed 1 000 GB high‑speed data allowance, after which the speed may be throttled. The plans are valid for 4, 7, 10 or 15 days, with pricing ranging from $10.91 to $27.27 USD.
For travelers who prefer a clear limit, eSIM Cards offers fixed‑data options such as the 20 GB travel eSIM for 30 days priced at $25.22 USD, which delivers 4 G and 5 G coverage throughout Japan. Because a fixed‑data plan can be more economical for heavy data use, it may be a better choice than a capped plan that carries the “Unlimited” name.
Does eSIM Cards offer Japan eSIM with phone number and SMS?
eSIM Cards does not provide Japan eSIM plans that include a phone number or SMS capability. The only Japan eSIM offerings from this provider are data‑only plans. Travelers who need voice or messaging can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.
How many data plans does eSIM Cards offer for Japan?
eSIM Cards lists eight single‑country data plans for Japan, with prices ranging from about $6.76 to $27.05. The associated data caps span from 3 GB to 1,000 GB and the validity period for these plans is between 4 and 30 days. Some of the offers allow tethering, while the speed may be throttled after a certain threshold.
