1. Who is your SIM card provider? When the SIM card connects to the TL-MR105, what's the Internet IP address on the router?

  2. What's the model number of your camera? Does it store the video recordings on the Reolink NVR, which is also connected to the router?

I use a RLN8-410 nvr with 8 camera connected behind the NVR. the NVR has local LAN static IP and use a reolink UID procedure to send data flow on cloud. No port redirection, no UPNP.  using MR105 I cannot connected or control my NVR using app ( on remote connection ) .  there is no connection from reolink NVR and reolink app. Other app using the same technology ( without port redirection ) are right.

  3. How do you stream your camera remotely on your phone, such as via the camera's app to view its live feed, or stream the video recordings stored on the Reolink NVR via the Reolink app?

with reolink app I can view live stream or storage data stream.  the stream flows only through nvr.

  4. It's suggested to contact your camera or Reolink NVR's technical support to check if any settings need to be configured on the router for remote access, such as port forwarding.
