Frequently Asked Questions
Does Simfinity offer unlimited data eSIM for Japan?
Simfinity does not offer any truly unlimited‑data eSIM plans for Japan. All of the plans listed for Japan have a fixed data allowance, the largest of which is a 25GB plan with unlimited validity. For travelers who need more data, Simfinity provides fixed data plans such as the 10GB 30‑day “Japan” plan and the 25GB unlimited‑validity “Global eSIM” plan, both of which cover Japan and other destinations. Choosing a fixed data plan can be more cost‑effective unless a user requires very heavy data usage, in which case a larger data allowance may be more appropriate.
Does Simfinity offer Japan eSIM with phone number and SMS?
Simfinity does not provide a Japan eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only eSIMs for Japan. Travelers who need to make calls or send texts can instead use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.
