The answer to the question of WHY Verizon chose to turn off a feature intrinsic to Samsung phones was asked in a previous thread. In that thread, Verizon customer service adroitly avoided answering WHY the "call and text on other devices" feature was turned off for Samsung devices. Instead, of answering the question as asked they used their rather annoying customer service skills to offer their app Messages+ as a "solution" to their self created "problem" of not being able to call and text on other other Samsung devices such as my TabS7 and S22 phone.
The entire reason that I just upgraded to a S22 from my perfectly fine S8 phone is so that I could have this feature. I was previously using the most recent upgrade of the Verizon Messages+ app when it started to randomly not send texts to people with Iphones. The texts would appear as sent in the Messages+ app on my device but never appear on the Iphones. I thought I was being ghosted but in reality it was bugs in Verizon's app. This was never a problem prior to the Message+ app being updated. Of course, I uninstalled and reinstalled. I called 311 to report the problem. I used the Message+ app to send a trouble report to the developers. No response was ever given and the problem still exists right now.
Verizon forced us to use their Messages+ app and that app is bug ridden. I still can't get phone calls on my tablet reliably with it. Further, no one can hear me when using their app to place or receive calls. It randomly mutes my side of the conversation as well as randomly ends calls. My microphone works perfectly for other apps such as Zoom and What's App so it is definitely a Verizon Messages+ problem. After 3 months of dealing with the Message+ developers trying to resolve the problem (it got raised to a higher priority twice during this time), the problems still exist.
Bottom line is that in my experience Verizon ignores complaints, avoids answering direct questions, forces us to use their app and then doesn't maintain that app. If they force us to use an app it should be the best in the market place. In my experience it isn't and it can never be because they refuse to fix problems when brought forth by users. I recommend that you get another service. I will be getting one for sure.
