I’m considering to buy a Fairphone (probably will wait for the FP4). But I would like to know how if VoLTE works with T-Mobile NL. There is no mentioning of FP support on their website. But they did seem to sell them in the past.
I also wonder how the call quality is. I saw a few complaints on this forum. But that could be incidents. I hope the quality is better than my current Pixel 3. Which sometimes is unusable because the person on the other end of the connection is unable to hear me sometimes. More Pixel owners experience this.
