Appalling 4G signal strength. Disappointing!
SmartyTrousers You make some very good points.
But surely we know that things are not identical on Three and smarty because there is a difference in what phones will work on each network now that 3G is being turned off - isn't that so?
I think the difference in VoLTE compatibility is a difference at the phone end, not the network end. Specifically, that Three, being a full MNO, is more likely to have its carrier profile (including the specific configuration needed for the device to work with its VoLTE) deployed to different device manufacturers. My suspicion (and I'm happy to be corrected on this) is that the reason virtually all iPhones work fine on Smarty is because, in the absence of a carrier profile for the MVNO, the iPhone falls back to using the parent network's carrier profile. And hey presto - it works perfectly. I'm guessing in the Android world, maybe the device falls back to some generic VoLTE configuration in the absence of a carrier profile for the MVNO.
But you make a good point - from the perspective of the end user, if your phone works on Three but not Smarty, that is a definite difference in service.
