「[Warning] HiData SIM from Amazon Japan is a scam – PUK locked, no support, email bounces」
I purchased a HiData SIM card from Amazon Japan, but it is unusable – it's PUK locked.
I reached out multiple times via their official LINE support, but got zero response. Emails bounced back as undeliverable.
The service doesn't work, and the seller refuses to respond. This is highly unprofessional.
