2 out of 5 stars
Japan

“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 for Japan FAQ

Does Roamless offer unlimited data eSIM for Japan?

Roamless does not offer a truly unlimited high‑speed data plan for Japan. The plans labeled “Japan Unlimited” give 3 GB per day at full speed; after that 3 GB the data is throttled to 1 Mbps and can be returned to full speed by switching to Roamless Credits or a Data Plan.

Travelers who need more data without throttling can consider Roamless’s fixed 50 GB 30‑day plan, or the pay‑as‑you‑go options that provide 100–200 GB of full‑speed data at the current Japan rate. These alternatives allow for larger data allowances than the 3 GB daily limit without the 1 Mbps reduction.

Does Roamless offer Japan eSIM with phone number and SMS?

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.

How many data plans does Roamless offer for Japan?

Roamless offers 20 single‑country data plans for Japan and 41 multi‑country plans that include Japan. The non‑Pay‑as‑you‑go options span a price range from free to about $490 and provide data from roughly 500 MB up to 200 GB. Among these, 22 plans have a fixed data cap and 39 provide a daily data cap. Pay‑as‑you‑go credits are available in 22 top‑up sizes, with the credit value expressed as the amount of data that would be worth at Japan’s rates; unused credit does not expire.
