Call & text on other devices requires “Reset network settings” every other day

[Dan5678]

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+.

Any suggestions greatly appreciated.

Try this: Reset your phone then immediately turned the power off on your phone and leave it off for at least 15 minutes. Power phone back on and see how it is. Hope this helps.

Thanks for replying. When you say Reset the phone, do you mean Reset network settings?

Just hold your power button and three icons will come up, power off, restart and emergency off. Choose first the restart option your phone will turn off then turn back on I'll by itself. Next you will want to press and hold the power button again this time choose the power off option or icon and leave your phone off for at least 15 minutes. Then turn it back on manually you'll have to press and hold the power button until the phone comes back on then see how things are. Hope that works, let me know if you want.

I tried that and it didn't help. Any other suggestions?

Reboot your router do you know how?

[Dan5678]

I know how. I rebooted it a week ago and it didn't help.

Did you add a new phone or what changed when you first noticed the text messages glitch,

[Dan5678]

I think it has been doing this since I purchased the tablet.

For months.
