Dear Messrs. Hesse, Humm, Mead and Stephenson:

Images of the devastation and suffering in Japan have touched Americans nationwide, leading to an outpouring of financial support as the scope of this humanitarian disaster has become clear.

Advances in mobile technology have made it possible for Americans to contribute to relief efforts using their cell phones. Unfortunately, while those who have donated are likely under the impression that making a mobile donation means funds are being rushed to the affected area, the reality is it takes quite a bit longer.

In fact, according to mGive, one of the leading mobile donation platforms, it can take 30 to 90 days for mobile contributions to be distributed to relief organizations. This is because wireless carriers first register the donation from a customer, add that amount to the customer’s next bill, then wait until the bill is paid to transmit the donation.

In past global humanitarian crises, American mobile phone companies have remitted donations immediately to nonprofit organizations. In light of the scale of destruction in Japan, American wireless carriers should again immediately remit mobile donations to organizations conducting relief efforts on the ground.

Guaranteeing a speedy transmission of funds will not only match customers’ expectation that their donations are having an immediate impact but will also ensure that donations are rushed to those most in need.

I thank you for your contributions to the relief efforts thus far and I appreciate your swift attention to this matter.

Sincerely,

Barbara Boxer

United States Senator
