Each plan connects to the networks listed on its page, so you choose your carrier before you buy. Coverage varies by area: a listed network does not guarantee signal everywhere.
Frequently Asked Questions
Should I buy my Osaka eSIM before I fly or at Kansai Airport?
Buy it online before you fly, so you can install it at home over Wi-Fi and have data the moment you land. Kansai International Airport has counters and vending machines selling SIM cards and renting pocket WiFi before security, but an eSIM installed in advance saves queueing on arrival. The same Japan plan works on day trips to Kyoto, Nara and Kobe.

"This is the second time I've purchased an e-sim through this app. I was very satisfied the first time, so I continued using it. This time, I encountered a problem on my end and had trouble connecting. I submitted a support request by uploading my screenshots through the app. I received an email within seconds. We were able to resolve my issue very quickly. I sent screenshots via email one after another, and each time I received prompt responses within a few minutes. I was very pleased with the support lines. I recommend it!! ⭐️⭐️⭐️⭐️⭐️"

I love using it. The internet is a lifesaver for all of us everywhere, but it's especially necessary abroad, and having a reliable connection is fantastic. Even during my overseas vacations when I changed countries, I never experienced any internet disconnections or delays; the connection was excellent.
