A request to provision a trial service to a user device is received, and the trial service relates to offering a service to the user device during a trial time period. The request is confirmed as originating from the user device by forwarding a confirmation code to the user device, and receiving the confirmation code from the user device. Data regarding the user device is obtained and used to determine whether the user device is eligible to receive the trial service. For example, eligibility of the user device to receive the trial service may be determined based on a service provided to the user device before the request is received, and based on whether the user device has previously received the trial service during a particular time period. When the user device is eligible to receive the trial service, the trial service is provisioned to the user device.
