Haven't installed it yet but it appears well made. Very detailed Easy Instruction sheet as well as a manual. Not cheap but if it works as advertised it will be worth it. Uses 12 AAA batteries. Had to first go to my.simhero.com to register the SIM. That worked fine. While I have ATT for my phone I don't get 4G service at my home. The camera fell back to 3G. I will try it at the location I plan to use it and see the reception I get there. I took one test photo and had setup the SMS under 4G-EMail with my phone @ MMS.ATT.NET but never received a photo via text, though the camera said it sent it. I need to look into that further. I will report back with my experience with that and the quality of photos.EDIT: 6/6/2020: After configuring the setup was able to get a test photo emailed to me. Couldn't get the photo texted to me following the instructions for my cell provider ATT though. Will look at that again later. Test Photos were pretty clear and the ones sent in the email were only 47kKB. I did not download any off of the included 32GB SD card. There is an iOS app Trail Camera that appears to allow taking photos remotely but only works with an ATT sim card. It requires a phone number and the one included with the SimHero doesn't work.
