1. What should I do when I lost my sim card / my sim card is damaged?
2. I will return to my country for a few months. Could you temporarily deactivate my sim card within this period and reactivate it when I come back to Japan?
3. How to cancel my contract?
4. I forgot to make payments for a few months, and my service has been terminated. Can you reactivate it after I complete all the pending payments?
