Our take on the Unlimited Japan eSIM

A prepaid travel eSIM that gives unlimited 5G/4G data on SoftBank's network across Japan, activated by scanning a QR code with no ID registration. It runs up to 180 days and can be bought up to six months before a trip, so you can set it up in advance and switch it on when you land. Your home SIM stays in the phone, so your WhatsApp and usual number keep working. Against rival Japan eSIMs, the appeal is unlimited data and long validity rather than a fixed daily allowance; the trade-off is that it is data-only, with no local phone number for calls or texts.
