My usual SMS app is QKSMS, but I’ve also tried Simple SMS Messenger and the default Messages app. QKSMS gives the same error message as I’d get with no reception. Other apps mention airplane mode specifically as the reason why the message can’t be sent.
My current provider is ASDA mobile, which uses the Vodafone network.
Any idea what’s going on here? Is this an issue with the Vodafone network, something in android, a limitation in the Fairphone 3 hardware, or an oversight in the design of WiFi calling?
This is excellent. All signs point to Vodafone. I’m actually planning to switch to Honest Mobile, which uses the THREE network, so we’ll see if that fixes it.
I have no idea. I only just discovered that WiFi calling was possible on Fairphone 3/all the networks.
Mine says “No data used”. Interesting, but I’m not sure what that tells us. “Background data” is enabled, and it has all the permissions. Mmm installed via F-Droid, not Play store. Does that matter?
That was my reason to get a new phone as I have no mobile signal
No data used confirms the phone agrees with you and as for install I did the same from F-Droid
See if you can borrow another SIM before you make the change.
I also remember I had to find a network signal to enable full working of the Wi-Fi calling etc.
Switching from ASDA mobile (Vodafone) to Honest Mobile (THREE) fixed it. It’s possible something was misconfigured by me with ASDA mobile (APN maybe?) and it could have been fixed, but I’ll never know now.
