ANRAN 4g Security Camera

Has anyone ever been able to add this device to the ANRAN app and use it with a T-Mobile Sim card? I have a T-Mobile 500mb data plan and Sim card for security cameras, and have been able to connect to devices from three other manufacturers. But I like the loud siren and some of the other features for this ANRAN camera, and would like to use it. I have verified the MMC, MNC, and APN settings with T-Mobile, but I still can’t not get the camera to connect to the net work. The Arlo camera sold by T-Mobile is too limited and its functionality, and has some terrible reviews. I won’t even bother to demo this camera. Any help would be appreciated.
