[MENTION=10045355]boardsports[/MENTION] - Yup, Sim2Fly eSIM reseller was mentioned by [MENTION=320827]beep88[/MENTION] on the Japan Forum https://www.flyertalk.com/forum/30832359-post482.html The physical sim cards purchased from resellers are registered to someone else (not the purchaser) and prevents some of the functions of app working when Line Pay used to be available to US Line holders. MobileTopup checkout uses Verified By Visa 3DS and Chase CC's are a bit fiddly with that Always stuck in the Verified by Visa when purchase ticket....Any solution?? though I'd probably pre-load some more credit on an eSIM than physical as I lend out physical sims.
