I'm using moultrie XV-7000i. The V stands for verizon, they also sell an XA-7000i (AT&T)
I'm in it for about $105 after rebate, cellular plans vary on how many photos you need to receive per monthly billing cycle. I am currently paying $14.99 per month for 1500 pics. Adjustments to camera settings can be made from your PC or smart phone. My camera is set up in terrible cell service area, my modem signal strength reads 0%, yet it somehow gets the photos out to me.
I've been using mine for one month, so far I am happy. I feel it is a decent value.
