Major wireless providers give customers an option to view current and past bills online. The wireless account needs to be registered online before online bills can be accessed.
Verizon wireless gives customers access to their current bill and past bills from the last 18 months. T-Mobile retains bills from the past 12 months online, and older bills can be obtained through T-Mobile customer service. Sprint provides access to 24 months of bills for individual accounts and 13 months of bills for business accounts. Online paperless billing is becoming more common, but even if you still receive paper billing, you can view current and past bills when the account is registered online.
