Do you have to have ATT
Love my Spartan. AT&T SIM card. Takes some time to get all of the settings dialed in. Now that mine is dialed in just how I want it, battery life is great and I receive photos within 2 minutes of motion detected. $399 for the camera and $25 for 3 months of data.
I do have an AT&T Spartan Camera. My cell phone is also AT&T but that's irrelevant. The SIM card in the camera is a seperate account.
Like previously stated, I have 2 bars of service on my Spartan and it works perfectly.
There are booster antennas for Spartan cameras. I have one but haven't tried it yet. I have a friend that swears by his booster antenna.
