Since switching to iD, I've noticed that there are certain locations where though my phone shows a good 4G signal, I don't seem to be able to use my data. Toggling to airplane mode or rebooting my phone doesn't appear to fix the issue, but setting my phone to only use 2G/3G resolves the problem.
The problem seems to be repeatable in set, but un-related locations. 4G works perfectly everywhere else.
Obviously one way to resolve this issue is to only use 3G or to switch when the issue occurs, but it would be nice not to need to do this, plus there are benefits in reach of 4G in indoor locations - anyone got any ideas on what the problem is or is this just an infrastructure issue?
The issue occurs om my Huawei P20 Pro (unbranded) and also on my wife's Huawei P10, who is also on iD. The Huawei P10 was previously on O2 and didn't have this issue in the same locations and I have a corporate phone which was originally on EE and now is on Vodaphone, again with no signs of 4G issues.
