I have ATT as my carrier and I checked 4G coverage on their website for the location I wanted to use this camera which was several states away from me. I ordered a universal SIM card selecting the option that I was going to use it in a tablet. ATT mailed me the sim card and added it to my account. I put the camera together and verified that the sim card worked. I fully charged the camera with the included cable and then took it to my location and mounted it by screwing the bases into a tree. I had the solar panel kit and connected that. The camera showed 4 out of 5 bars of 4G at this location.The app software is pretty good, a little more complicated than I think it needs to be. I have a hard time getting to the sections of the app I use the most, like looking for the battery charge indication, any captured movement film clips, etc. To get email notifications, the app wants your email address and your email account password. I use Gmail and Gmail does not like the app and blocks any attempt by the app to get into Gmail, so I can't use this function.Connection and quality is a little inconsistent, though this is most likely network related and my setting the camera for the highest quality picture. Sometimes I get the best results when using my WiFi only tablet to connect to the camera. It pans the camera almost instantly even from several states and thousands of miles away. Using my cell phone with 5G to connect to the camera with the app I will get a clear picture, but the panning has several seconds of delay and lags. Sometimes, no matter what device I am using, it takes almost a minute for the camera image to come up, I will get an updated, yet frozen image, with "loading stream" and "connecting" messages for up to 30 seconds to over a minute. With panning, the camera will have a current signal because the time stamp will update but it just won't pan no matter how long you direct it too. Switching to the app on a laptop during all of these issues, I was able to connect quickly and pan with some minor delay after directing the panning, but I have had times when the tablet has trouble loading and then switching to PC it also takes some time. Once again, I think this is all network depending on time of day and what is going on. I do think I prefer the PC app better than the mobile version for navigation, function and the panning control (not a fan of the app panning control "buttons").The battery with the solar panel so far is awesome. After a week of February cloudy days, rain, wind, and a solar panel location that only gets half day sun filtered through trees, I have not gone under 98% battery and have gone back up to 100% several times. This is with checking the camera for a few seconds several times a day and doing some panning. The microphone picks up sound pretty good (though where my camera is, I all hear is the wind and grass rustling). I haven't tried talking to the woods and forest animals with the speaker function.Night vision is pretty good. I had some moisture or water drops on the lens which the IR caught and illuminated so it gives off glowing round reflection on parts of the picture at night.Overall, very impressed with the picture/video quality especially during the day. Very cool how I can be thousands of miles away and watch my plot of land that has no power or internet.
