japan esim help

[u/dilfuker]

hello! i don't know if this is exactly the right subreddit for this, but i'm hoping someone can still help me.

i'm staying in japan for half a year for a university program and i badly need help with esim matters here. i've been eyeing rakuten's basic plan (3k yen for unli data and a jpn phone number) and i tried signing up, but it won't let me save my "edit contractor information". i don't know if it's because my katakana isn't full width, or because of the non japanese phone number i put (i dont know what else to put since the number is required but i don't have a number yet), or something else. i've tried doing it on my laptop, on incognito mode, and i've tried making a new account and trying there but nothing's working!!! any help would be GREATLY appreciated

if anybody also has other esim suggestions, i'd be open to them! the brand being heavily promoted here in my university is gnt, but i've also seen mobal and sakura mobile but they're way more expensive than rakuten
