関連FAQ	After "Omatome Seikyu Service (combined billing method)" starts, can I check my call history and detailed charges of my phone calls on "Web Billing"? While using "Denwa Bango Hokan" (Service to have NTT docomo keep your phone number for up to three years and reactivating it again after you come back to Japan.), can I apply for "Omatome Seikyu Service (combined billing method)"?
