T-Mobile's decision to offer a "data only" wireless plan, thereby eliminating charges for unusable voice minutes, also played a role in the device's dominance in the deaf community. Additionally, some local deaf non-profit groups in the U.S. will either pay all or part of the cost of the device/monthly service fees for the user to keep them "connected". Other groups have set up discount programs, where Deaf users receive a discount on the cost of the device and monthly service fee based on the number of members in the group.
