Had this S20FE 5G less than 6 months and I am sick of constantly losing internet connection. I don't use WiFi so it's not a router problem it's the phone.
Tried everything ready to throw the phone in the bin
Have you tried network reset ?. From settings > General management > Reset > Reset Network Settings. Also any Bluetooth devices will be un installed, so after you will need to re install. Or contact your carrier for a replacement SIM card
