My Wi-Fi only S7+ will send and receive SMS text messages for a day or two. Then, when I send a message, it spins for a while and eventually gives the error: Couldn't send message.
The only fix is to perform a "Reset network settings" on my S20 FE 5G cellphone.
Is there an easier or permanent fix? Resetting network settings causes me to lose my Wi-Fi settings, and my Bluetooth connections to my watch and my car.
I have tried all of the following when the error occurs. None of them worked.
Wipe entire cache partition on S7+.
Turn "Call & text on other devices" off and back on for both S20 and S7+.
Reset Network Settings on S7+.
Restart S20 and S7+.
Wipe cache and data on S7+ Messages app.
Turn off Battery Optimization for "Call & text on other devices" and "Messages" for both.
Clear the cache on the Samsung Messages app on S20 and S7+.
I have similar issue with Call and text app. I have 2 devices Samsung A52 and TabA7 both about 6 months old. Iv'e set everything up and my tablet will RECEIVE the text messages, but will not send them. I've tried EVERYTHING in this thread with no results. HELP
I gave up on Call and Text many months ago. I have installed the Google Messages app on both my Galaxy phone and tablet. Once I paired them together it works great.
