I considered Cuddelink because I wanted to put out a bunch of cameras around the property with only one data plan. ...but based on bad reviews of the app / interface, etc., I went with Tacacam Reveals.
The cheapest tacacam data plan is $55/year per camera. That cheap plan doesn't give you live view, on demand pictures, or provide videos. you can upgrade for those features including unlimited pictures, but the app features and usability are great, and getting a near instant notification when a camera sense motion and takes a pic is great. ..can share with my sons so they can see all pics in the app on their phones too... and i just adjust the delay between pictures / turn off "burst" so i don't go over the cheap data plan in any given month, which would result in either no more pics that month or agreeing to $5 overage charges to keep taking pictures that month. and tactacam and accessories (rechargable batteries, solar chargers, t-post mounts, etc.) are sold everywhere - academy, bass pro, buc-ee's, etc. ...then again, I have nothing to compare to.
