Hi. Joined iD this week on Paym plan. Wifi calling works fine but no VoLTE/4g calling. Tried with a few phones including Note 9 and S9 - both bought directly from Samsung UK, neither show VoLTE. Checked coverage and 4G calling enabled in my area. Phone is setup right, used VoLTE with EE before.
Any ideas? Wonder if the CSC code or something to do with the particular Note 9 model is not fully set up on the iD side, but weird that wifi calling works.
