The U.S Nationwide camera will work with AT&T, SPRINT, T-MOBILE & US Cellular provider.
The V or VZN at the end of a camera’s name means Verizon and will ONLY connect with Verizon towers.
The provider that you choose depends entirely on where you are planning to place the camera.
The best way to know is to look at the coverage maps from Verizon and AT&T and identify which provider will give you the best coverage at the location you want to deploy the camera. The coverage maps come directly from the cellular provider and give a good idea of the cellular network in different areas.
