“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 currently provide a plan with an unlimited data cap for Japan. Their largest fixed‑data options for Japan offer 200GB, 150GB, or 100GB of high‑speed data with an unlimited validity period. Additional choices include a 50GB plan valid for 30 days. These fixed data plans can be more cost‑effective, especially for travelers who anticipate a high but finite data usage, whereas plans with unlimited data caps are not available from Roamless at this time.
Does Roamless offer Japan eSIM with phone number and SMS?
Roamless does not offer any Japan eSIM plans that include a phone number or SMS capability. The provider supplies only data‑only eSIMs for Japan, so travelers cannot receive or make calls through a local phone number or send traditional SMS messages. Instead, users typically rely on data‑based messaging and voice services such as WhatsApp, Telegram, or iMessage to communicate while abroad.
How many data plans does Roamless offer for Japan?
Roamless currently offers 28 single-country data plans specifically for Japan, alongside 12 plans that include Japan as part of a wider multi-country coverage area. These plans range in price from $0.00 to $490.00 and offer data allowances between 525MB and 200GB. Some plans feature a pay-as-you-go option, while others provide a fixed data amount or a validity period ranging up to 30 days. Certain offers may be exclusively for new users, and tethering is generally allowed.
