Hi there all 
Just bought a huawei p20 pro dual sim not sure of the model number.
I was looking for a dsda which i could not find nothing not even Chinese hand sets and it like no one likes talking about it not in UK any way.
To the point, I was testing the dual capabilitys I put a three sim in to sim 1 and giffgaff in sim 2 when I ring sim 1 (Three) off another phone then answered it, then off another phone ring sim 2 (giffgaff) I answer, and have sim 1 (Three) on hold I can switch between the 2.
Now if I ring sim2 (giffgaff) and answer then try and ring sim 1 (Three) in some cases you can hear the phone ring on the hand set you are ringing from but not the attended phone.
In most cases it diverts to the answer machine of the sim 2 (giffgaff) a little weird
I'm thinking this could be down to the fact that giffgaff pigies off o2 which uses 2 frequency for 4g and Three uses 1 frequency (I may be wrong)
What's the best adsa phone even Chinese makes if anyone knows of any.
And no replays that don't understand dsda, meaning pointless comments telling me about their phone and what it does most phones are dual standby we know this and probably yours too :laugh:
Don't mean to be rude but a little annoying.
