I am visiting Asia (Japan) and my prepaid SIM card will not register with any network. I have credit. I have reset everything on my phone. I have tried my SIM in another mobile phone. It does not register.
Is that usual that a prepaid SIM will not register in Japan?
MOST IMPORTANT: How do I ensure that my account is not closed or my SIM is not deactivated before I return to the Netherlands next week?Â
