USB tethering with my VM SIM on previous Nexus 5x phone was fine.
On my new POCO F3, the same SIM works in all other respects (except that the My Virgin Media app can never validate it) but USB tethering is not possible in either SIM slot. The PC connects to the phone and sees the network adapter created by the phone but it appears that DHCP configuration never happens and so there is no IP number or working network. An iD SIM in the same phone works correctly.
I have another Nexus 5x - this was never used with the VM SIM and it behaves like the POCO - normal except for the My Virgin Media app and no DHCP configuration when attempting USB tethering. It is almost as if the VM SIM is partially locked to the Nexus 5x in which it was previously used.
Anyone seen anything like this? Suggestions?
