Question about Lexar Pexar 11" Digital Picture Frame 2K resolution WiFi enabled 32GB

This is possible without any problems. The picture frame must be connected via WLAN. You can then connect to the app and send files from any location.

Yes you can, as already answered, you can then send pictures to the frame via the app if it is connected to your parents' Wi-Fi. You will hear a sound when new pictures are available. We don't have a plan: It's a shame that you can only see which pictures I have sent in the app. You can't see which pictures are actually on the frame (if several people send pictures), and I can't delete/replace sent pictures from the frame in the app. You have to sort pictures (you can create albums) and delete them in the frame itself.

Yes, you can easily send pictures to the frame via a WLAN connection. The free app allows videos of up to 30 seconds; a plan is required for longer videos. I am very happy with this frame.

Yes, you can easily send pictures to the device from anywhere using the corresponding app. A plan is only necessary if you want to manage the photo frame via the app.
