When I use two sim cards I get strange effects depending on how they are configured affecting MESSAGING and WIFI CALLING:
In MESSAGING the "group message" option is missing altogether. I turn off the second sim card and the option reappears and is set as I had it (i.e. turned "on"). I then re-enable the second card and it continues to work for a while. When it fails, I repeat the process to fix it.
In WIFI CALLING: with both sim cards on and with the options "Messages" and "Mobile data" both set to the first card, wifi calling does not work. If I set "Mobile data" to the second card, wifi calling works fine using the account associated with the first sim card.
And if that isn't complicated enough, when "mobile data" is set to the second chip, the multimedia messages don't automatically download, even though the option is set. When I change "mobile data" back to the first sim card, auto-downloading works fine.
The first card is the one from t-mobile in the US. The second card is set to a local carrier here in Costa Rica.
