video call

I assume you have a Samsung, he has an iPhone?

they aren't compatible.  In order to video call you have to have Samsung devices with the feature, both on ATT service.   

If you have different brand phones, you can always use Skype to make video calls which is free to use (other than any data you may be using).

I made a video call or received one a few weeks ago different devices and it worked and since then it won't work any longer. I get the iphone and samsung ( don't like it but I get it) So my question is why not state that on the support site instead of everything else. Say you must have the same brand of devices or your devices may not be compatiable. If I am wrong in this please let me know.

Some devices, and protocols for video calls may not be compatible (there are standards, but I'm sure some vendors re-invent stuff, just for whatever...).

What is for sure, is that both apps (built-in or otherwise) MUST be using the same protocol (the handshake stuff that connects the calls, and the formats for the data transfer: your video/voice).

One sure-fire way to get around this mess, is to go with a third-party video calling app, such as Skype, Google Voice, Viber, and many, many others.

It's far easier to match these versions, so that protocols aren't an issue and everything "just works".

The downside is: You have to use your regular data, whereas I think if you use a carriers' built-in video calling app, they often count it as a regular call, and not against your data usage.

If you're on WiFi, well then it's most likely a non-issue, unless you're going to talk for many, many hours, you probably won't affect your wired internet plan threshold, much.

I just found out about Google Duo.  It's video calling across platform android and iOS.  As usual Windows is left out.  It works great on cellular, I'm using a non ATT phone.

Unlike the Samsung video calling you aren't limited to ATT Samsung phones.

Google has released a new version of its Duo video calling app for Android tablets and iPads. But I've an guide by which you can able to download Google Duo on PC.
