Not all SMS campaigns advertised as FTEU may be available on the Thumb
Cellular's network, however where they are it is Thumb Cellular's intention
to ensure no charge or fee is raised for the service. For some pre-paid
services this may prove to be a challenge and users may find a charge is
indeed incurred. In such cases the user should contact Thumb's customer
service to request a refund. Contact customer service at 1-800-443-5057
