UBR LTE - video chat and number of internet connections

Hello Peplink community,

I’m looking at getting the UBR LTE for improving video conferencing quality via applications like Webex and Teams while travelling in South America. I have two questions. First, the marketing email introducing the product in this forum did not recommend the product for video streaming. Why is that? I see the specs at 120 Mbps/50 Mbps, which should be more than enough. Second, how many simultaneous internet connections will this device support for use with bandwidth bonding and WAN smoothing? I understand it will combine two cellular connections, but will it also combine with those, the wired WAN connection and the wifi WAN connection, for a total of four internet connections? Also, does enabling the wifi WAN connection disable the wifi client function, as one message on this forum has noted?

Thanks for any advice.
