Frequently Asked Questions
Does thirr.com offer unlimited data eSIM for Japan?
thirr.com does not provide an unlimited data eSIM plan for Japan. All eSIM offerings are restricted to a defined data cap.
Travelers can choose from fixed‑data plans such as JP 50GB 365D, which offers 50 GB with a 1‑year validity, or the JP 30GB 30D plan that gives 30 GB for 30 days. These options give sizeable data limits and may be more cost‑effective for most users, although very heavy data consumers might prefer a larger or lower‑price plan.
Does thirr.com offer Japan eSIM with phone number and SMS?
thirr.com does not offer a Japan eSIM that includes a phone number and SMS. Only data‑only eSIM plans are available for Japan.
Travelers who need to send messages or make voice calls can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging without a phone number or SMS capability.
