I built Lantravel. I'm an engineer, and the product is simple: every order comes with two native Japanese carrier eSIMs (KDDI + SoftBank) so you have a main line and a backup. If the connection fails, you switch on your phone instead of contacting support.
Not positioned as the cheapest. We stacked the two most reliable cards, so it costs more. If stability matters more than price: https://lantravel.net
