Welcome to Vodafone Community
I have poor reception in my house from pretty much all the networks, so rely on WiFi Calling hugely but recently it's become very unreliable and hardly ever works when I make or take a call which makes it my Samsung s10 useless as a phone in my house on Vodafone. Often when I reboot the phone the wifi calling function returns but then it will go again and having to reboot all the time is not a good solution especially when you don't know when you're going to receive a call. I've contacted Vodafone using IM and they said they said they rest the wifi calling function which worked for a bit but then it started dropping out again. Very frustrating.
Is it because your phone is switching it’s connection to you broadband router between 2.4 and 5ghz frequencies? I think it needs to lock in one this maybe issue but you would need to check with your broadband provider. I’m no techie but this was issue for me.
Hi @PixelBadger This isssue is known to Samsung, users are experiencing unexpected data loss, or voice issues on Samsung Galaxy S10, S10+ or S10e phones. A software upgrade will be released soon. When it is, you can update your phone by opening Apps > Settings > System updates > Download and install.
