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.

The following chart shows some of the long-term plans that each service offers. As you can see, all the plans for each service are slightly different because all services offer different plans (what’s comparable on this chart is pretty much only the price per GB).

SIM vs eSIM

If you’re traveling abroad and need internet connectivity, a regular SIM is a physical card you insert into your device. It’s tied to a specific carrier and phone number. In contrast, an eSIM is a digital version that’s already built into some devices. With an eSIM, you can switch carriers remotely without changing physical cards, making it more convenient when traveling as you can easily switch to a local carrier in the country you’re visiting without the hassle of finding and inserting a new SIM card.
