Customers applying for postpaid service must prepare the original address proof in advance (a copy of the address proof is required for applications to the online store, while the original is required for applications to a physical store). The address proof must be a document issued within the last three months of the application date, and must include the date of issuance and the name of the issuing organization. The recipient's name must also exactly match the name on your ID document.
