Frequently Asked Questions
Does Giga.Tel offer unlimited data eSIM for Japan?
Giga.Tel does not offer a truly unlimited data eSIM for Japan. The plans that carry the label “Unlimited” in their name—such as Global Unlimited 7 Days, 10 Days, and 15 Days—actually provide 14GB, 20GB, or 30GB of high‑speed data, after which speed is throttled to 512kbps.
Fixed‑data plans are available instead. For example, a 90GB plan valid for 365 days costs $143.49 USD, and a 50GB plan for 30 days costs $25.49 USD. The 50GB plan also reduces speed to 128kbps once the limit is reached. Choosing a fixed‑data plan can be more cost effective unless an extremely heavy data consumer requires unlimited throughput.
Does Giga.Tel offer Japan eSIM with phone number and SMS?
Giga.Tel provides only data‑only eSIM plans for Japan, so there is no phone number or SMS capability included with its offerings. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging needs.
How many data plans does Giga.Tel offer for Japan?
Giga.Tel offers 24 single‑country and 30 multi‑country data plans for Japan, with prices ranging from $4.49 to $199.49 and data caps between 500 MB and 90 GB. Within those plans there are 12 daily data‑cap options and 42 fixed data‑cap options.
