I get faster download speeds on 3G than 4G (19mbps on 3G vs 10mbps on 4G) but upload speeds on 3G are a lot slower at 2.98mbps vs nearly 20mbps on 4G. The slower upload on 3G may be the issue here but I would have thought for voice data nearly 3mbps should be plenty. I did try with 4G disabled and it did not seem to make much difference when I tested calling my brother.
I did a test calling Three's answerphone and recording my voice a few times and although it sounded a bit digital in nature I had no real issues understanding what was being said on playback. I tend to believe it may be somewhat more complex than at first glance.
Just to add I just had a long conversation with someone whilst typing this up and had it switched over to 3G. I'm not sure if it had any impact but I asked the caller if there were any issues understanding me to which he replied no which is good. We were both on hands free too.
It seems to be my brother who is also on Three who complains the most. Hmm.
BTW I already asked Motorola if the X Force supports VoLTE and they replied that that is does not at present and have no idea if it ever will.
What's my speed? Who knows thanks to DLM! Plusnet FTTC. Openreach are pants!
