Possible ThrottlingFrequently Asked Questions
Does eSIM Cards offer unlimited data eSIM for Japan?
eSIM Cards does not provide a truly unlimited highโspeed data plan for Japan. The plans that carry โUnlimitedโ in the name actually offer a fixed data allowance of 1,000GB, after which the network may throttle speed. For travelers who need a large but capped amount of data, fixedโdata options are available, for example the Japan 20GB Travel eSIM that lasts 30 days. Choosing a fixed data plan can be more costโeffective unless you are an extremely heavy data user.
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 dataโonly 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 singleโcountry data plans for Japan, with prices ranging from aboutโฏ$6.76 toโฏ$27.05.
