Hi there... Really pleased with my Huawei Mate 20x - I've loaded it with an EE SIM and an O2 SIM. Both work, even though the phone was shipped from EE and was "advertised" as locked to EE. O2 is fine and even though 5g is not yet announced in the UK for O2 until October 2019, I see the 5gb symbol appear on the O2 SIM, and yet NOT on SIM2 (EE) - for that I see 2g/3g/4g.
This could simply be labelling them the other way around, but I wondered if anyone is uing dual sim on two different UK networks? (especially where one is 5g ready and the other isn't)
Great phone in any case...
One last question - is this phone Wifi 6 enabled (i.e. 802.11ax? )
