“The internet worked perfectly everywhere – airports , even on road trips. No annoying "loading..." screens! Plus their customer chat is LEGIT. Messaged them at 1AM (jetlag lol) and replied in 2 minutes. She literally stayed on chat while I set it up, double-checked everything. Way cheaper than my phone plan back home. Never going back to regular SIM cards!”
“I used their unlimited 3-day plan and could use more than 20GB of data, so it seems to be indeed unlimited. However, the speed was capped at 10 Mbps the whole time.
Traffic was routed through Hong Kong, so the latency was not great but not too bad.
The issue with a Hong Kong IP is that I couldn't access some services like ChatGPT.”
iRoamly offers unlimited data eSIM plans for Japan with validity periods ranging from 1 day to 30 days. Prices start at $2.80 USD for a 1‑day plan and go up to $75.00 USD for a 30‑day plan, all of which operate on 5G and have a maximum speed of 20000kbps; speeds may be throttled after heavy use under a fair usage policy. If you need details on how much data remains at normal speed after a high‑usage period, please contact iRoamly directly.
iRoamly does not provide a Japan eSIM that includes a phone number SMS service. The provider offers only data‑only plans for Japan, so travelers cannot make or receive regular phone calls or text messages. However, call and messaging apps that operate over the internet, such as WhatsApp, Telegram, and iMessage, work over the data connection and can be used for voice, video, and text communication.
iRoamly offers 155 single‑country plans and 46 multi‑country plans for Japan. The available plans cover a price range from $0.00 to $257.00 and a data cap range from 500 MB to unlimited. Validity periods span from 1 to 365 days. Travelers can choose between fixed‑data plans that give a set amount of data for the entire validity period and daily‑cap plans that limit usage each day, allowing flexibility based on usage patterns.
