SIM card for phone calls

Hi, I'm staying in Osaka, Kyoto and Tokyo for like 20 days and i just found out yesterday that the debit card I rely on for cash extraction was deactivated.
I tried using other cards but: debit cards ask me for a PIN at an ATM and I cant configure them, I also tried setting no PIN at a 7 eleven and didn't work; and credit cards do work with PIN BUT the issuer set a limit of roughly 10 usd of extraction in my country's currency.

So basically, I need to call the card issuing company (VISA) with an actual phone number so I'm looking for a prepaid SIM card that would let me do that so that I can expand that limit

I'm also open to ideas since my phone company does not have roaming in japan, so I'm disconnected from the phone line
