T-Mobile Relief Efforts for Hurricane Sandy

November 20, 2012

Bellevue, Wash. — Nov. 21, 2012

Many T-Mobile customers have been directly impacted by Hurricane Sandy, and our thoughts are with them, their families and loved ones. The size, scope, and impact of hurricane Sandy are unprecedented in the U.S. in terms of geographic area, location, and population density. In recognition of this, T-Mobile has taken many steps to assist our customers, as well as to assist with the overall relief efforts.

T-Mobile customers on postpaid plans in New Jersey, Delaware, Connecticut, Rhode Island, and parts of New York will receive a credit to their bills for overages incurred during the storm for domestic voice, text message, and data usage for one monthly bill cycle. Customers will still be responsible for paying their monthly recurring rate plan charges and associated taxes as well as charges for international usage, domestic roaming, and one-time charges. Credits will be issued to customers depending on their billing cycles.

Customers whose primary place of use is in the following areas will receive the benefits described above, and can learn more by reading this FAQ document (http://support.t-mobile.com/docs/DOC-5174):

  • New York: Bronx, Kings, Nassau, New York, Orange, Putnam, Queens, Richmond, Rockland, Suffolk, Sullivan and Westchester counties.
  • New Jersey: Middlesex, Hudson, Essex, Morris, Bergen, Passaic, Union, Somerset, Sussex, Monmouth, Warren, Hunterdon, Ocean, Salem, Camden, Burlington, Gloucester, Atlantic, Cape May, Cumberland and Mercer counties.
  • Delaware: New Castle, Kent and Sussex counties.
  • Connecticut: Hartford, Litchfield, Tolland, Windham, New London, New Haven, Fairfield and Middlesex counties.
  • Rhode Island: Providence, Kent, Bristol, Washington and Newport counties

In addition to these efforts to help our customers who were most impacted by the storm, T-Mobile provided assistance to the American Red Cross with cash donations and in-kind products and services that were used to provide calling capabilities for those utilizing Red Cross shelters throughout the state of New Jersey. The company also continues to make text-to-donate opportunities available to all of our customers and employees who wish to contribute to the Red Cross relief efforts. T-Mobile customer donations to the American Red Cross, combined with T-Mobile’s donations, matching gifts and in-kind products and services, now total more than $850,000.

T-Mobile has also provided emergency relief via mobile charging solutions in particularly hard-hit areas, including the Rockaways and in Staten Island. Additional charging and free calling and emailing services were provided to anyone who needed these services, from all of T-Mobile stores in impacted areas as soon as they were re-opened after the storm.
