Best eSIM Services in Japan

Getting an internet connection when traveling abroad is one of the first things you will worry about when making travel plans. Nowadays, there are various ways you can get an internet connection. Some options are free but not so convenient while other options may be really convenient while also being expensive.

One of the most recent ways of getting a good internet connection is to use an eSIM service. In this article, I will introduce to you our picks for the 5 best eSIM services in Japan. Hopefully, this will help you to consider getting one of these on your next trip to Japan.


What is eSIM?

Before going right into the list of the best eSIM services, some of you might be thinking “what is eSIM?” and that would be a fair thing to ask since this is a relatively new thing that’s becoming more talked about.

The word eSIM stands for “Embedded SIM”. This has been a thing since 2016 and most mobile phones nowadays will have this feature. The eSIM replaces the need for a physical SIM card. Compared to the traditional SIM card, it is cheaper since it doesn’t require a physical card and is easier to install; you only need to scan a QR code or install an app on your mobile phone.

Although this technology has been available for a few years, it didn’t catch that much attention until Apple announced that iPhone 14 will go completely eSIM. This means if there are companies that haven’t supported eSIM, they are also going to start supporting it. eSIM is going to replace the regular SIM. Although for the foreseeable future, providers will still provide physical SIM cards, the eSIM will definitely become the standard.

Ok, now that we know what eSIM is, let me introduce to you 5 of the best eSIM services in Japan.

*Note: As I previously mentioned, most mobile phones nowadays will be compatible with eSIM. But still, be sure to check first before making any purchases.
