I just purchased the Galaxy S21 Plus, and I'm having trouble receiving text messages from my wife's android cell phone while I'm at work. The only way I can receive her messages is if I turn on data. My old Galaxy Grand Prime could send and receive text messages with the data turned off while I was at work. Any suggestions? I'm a 65 year old that doesn't know too much about these gadgets and could sure use some help.
Thanks so much!...Peter
