When a device is locked (or “simlocked”), it means that you can only use a SIM card/eSIM profile from the carrier from which you bought your device.
To know if your iPhone/iPad is locked/unlocked by your provider, go to : – Settings – General – Information – Carrier lock : you will see in this field “NO SIM restrictions” or “SIM restricted”
In case you have “SIM restricted”, you just need to contact your carrier (from which you bought your device) and request the device to be “unlocked” (you just need to provide its IMEI that you can find under the Settings or dial *#06# to display it on your screen).
After that, your device will be unlocked automatically, and you will be able to use any SIM card and any eSIM profile on it.
NB : Please note that some devices are equipped with an eSIM, but you will not be able to use it, whether your device is locked or unlocked, as this eSIM feature can be restricted for some markets/countries. In this case, we advise you to contact the device manufacturer for more information.

I couldn’t get connectivity for…
At the I couldn’t get connectivity for a while. I thought it was to connect as soon as I landed in Japan but I couldn’t . I waited about half a day before it worked. Today I read an email saying there was a service interruption .

Works pretty good
Working pretty well had just few times that it had some issues. But altogether so far have been quite smooth sailing with this internet service. Funny that it works so well when we stayed in Okinawa but the connection issues what I have experienced have been in Tokyo. Just short issue not anything major. So altogether great service.

Japan from Australia
Arrived in Japan from Australia and had no issues with internet connection for the 8 days. I visited Kyoto, Osaka and some outer regions ~2 hours from the cities. Thank you

Good Experience
I have had a wonderful experience by now (it's been almost 2 weeks), especially after I had no connection for some hours, but they understood/recognized/apologized about it, and sent a small gift in return.
I cannot know about future, but right now I go for 5 stars :)
