In cell phone industry, locked and unlocked refer to whether a cell phone will work with SIM cards from different carriers. For example, if a GSM phone or camera is unlocked, it will work if you put an active T-Mobile or AT&T SIM card in it. If it is locked to AT&T, you can only use an AT&T SIM card; likewise, if it is locked to T-Mobile, you can only use it with T-Mobile.
In the wireless scouting camera industry, unless specified, cameras are unlocked. This means that you can take your wireless scouting camera to any compatible carrier to activate your camera if the carriers you are going to use are willing to do it for you. Activating your camera means:
- Activating a SIM card (AT&T or T-mobile) when you have a UMTS/W-CDMA 3G camera.
- Activating your actual device, when you have a CDMA2000 camera (Verizon, Sprint or US Cellular).
