Frequently Asked Questions
Does Spark Roam offer unlimited data eSIM for Japan?
Spark Roam does not provide an unlimited‑data eSIM plan for Japan. The plans it offers for Japanese travelers have fixed data allowances.
For example, a 50 GB plan is available for 30 days at $21.25 USD and a 20 GB plan for 30 days costs $10.24 USD. These fixed‑data plans can be more cost effective unless a user is an extremely heavy data consumer who would otherwise need an unlimited plan.
Does Spark Roam offer Japan eSIM with phone number and SMS?
Spark Roam does not provide eSIM plans with a phone number or SMS capability for Japan. All of Spark Roam’s Japan eSIM offerings are data‑only, so travelers cannot receive or send SMS or make traditional voice calls through a local number. However, popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and can be used for calls and messaging without a phone number or SMS functionality.
How many data plans does Spark Roam offer for Japan?
Spark Roam offers seven single‑country plans specifically for Japan and, in addition, nineteen multi‑country plans that include Japan among their coverage. The plans range in price from roughly $1.33 to $111, with data capacities spanning 1 GB to 50 GB and validity periods between 7 and 365 days. The single‑country options are limited to use only in Japan, whereas the multi‑country plans allow usage in Japan along with other destinations within the same subscription.
