MrsIHN and I both have Pixel 7a phones and have recently switched to Spusu SIMs. Spusu uses the EE network.
The phone signal where we live is poor, EE is the best of a bad bunch, so we rely on WiFi calling when we're in the house. However, we consistently have an issue where, when we make a call, it's fine for about a minute or two and then the person at the other end will suddenly not be able to hear us. We can hear them perfectly (saying "hello, hello, can you hear me...?"). At that point we just have to hang up and try again.
It seems worse on outgoing calls than incoming.
We had similar issues previously where the phone would move off WiFi calling to the phone network mid-call if it got a sniff of signal, but the Spusu SIMs allow WiFi calling to be set as the default, which it is. I've even tried it on Airplane mode with the WiFi turned on manually, so it's definitely not using the phone network, but the same issue persists
I suspect it's something related to the mesh network we have (TP-Link Deco, needed due to the thickness of the walls...) and the phone being handed off between nodes maybe, but any other ideas?
No QoS on the handoff perhaps. Is there a setting to enable QoS? Try unplugging all the other nodes and standing near the one left working and test??
