In addition, Verizon:
- Controls tethering ("Tethering requires you to have a usage-based data plan specifically for tethering".
See "Verizon's UBB Starts July 7; Tethering Surcharge: $20"- here.
- Deploys data and video optimization technologies ("Verizon Wireless is implementing optimization and transcoding technologies in its network to transmit data files in a more efficient manner to allow available network capacity to benefit the greatest number of users, and although unlikely, the process may minimally impact the appearance of the file as displayed on the mobile device").
See "Verizon Wireless Optimizes Web & Video using Transcoding, Caching and Buffer Tuning - here.
