Text messages wont download of 'both' WiFi and Cellular data on

[Android Central Question]

I have the Nokia 6.1 Android One phone on AT&T. When I have both WiFi and cellular on it buffers text messages and has the text 'Downloading'. When I turn WiFi off, the text messages load (this is both text only and pictures and text) I have version 8.1.0

Try going into the phone's main settings, then to About Phone, then into Software Info. Tap the build number box repeatedly until it tells you developer options are enabled (about 7 times).

Now back out to the main settings screen and you'll see the new Developer Options menu selection. Go into it and look for the option "Cellular Data Always Active." Turn this on and see if that lets your texts come through even with Wi-Fi connected.
