“I tried ordering the FREE plan and set it up on my iPhone SE2.
At first, the eSIM activation stayed in “processing on the server” status for about 10 minutes without any response, so I just left it for a while until it finally completed.
After that, the phone stayed out of service and couldn’t connect to the network for over an hour. I had almost given up, but eventually, it just started working on its own.
In terms of speed, there were no issues.
While using the service, I kept checking the data usage on the website, but after reaching 0.01GB, the connection stopped working completely. I thought maybe the usage display was just delayed, but even the next day, it hadn’t updated. It felt like I had used more data than what was shown, so the website’s usage display doesn’t seem very reliable.”
Roamless does not provide an unlimited data eSIM for Japan. The largest fixed‑data plan available is 50GB for 30 days, and the largest Pay‑as‑you‑go credit is 200GB, which can be used indefinitely as long as the balance is topped up.
For travelers who need a large amount of data, the 200GB Pay‑as‑you‑go plan offers the most generous allowance, while the 50GB 30‑day plan is a more economical option for shorter stays. Fixed‑data plans may be more cost‑effective for most users, whereas Pay‑as‑you‑go plans give the flexibility to add credit as needed.
Roamless does not offer a Japan eSIM plan that includes a phone number or SMS capability. All of Roamless’s Japan offerings are data‑only, so travelers will receive a high‑speed internet connection without a local calling or texting feature.
Travelers who need to make calls or send messages can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, they should verify that these services are accessible in Japan before purchasing, as some destinations may impose restrictions on particular apps or VoIP services.
Roamless provides 6 single‑country data plans and 13 multi‑country data plans for Japan, excluding the Pay‑as‑you‑go offerings. The available plans cover roughly 0.5 GB to 200 GB of data and are priced between about $0.00 and $490.00, offering a broad range of options for travelers.
