Hello,
I am on Boost Sim, and my overall connection is pretty poor on my Sony Xperia 1 II.
What's worse is that I do not get 5g. I have never seen the phone connect to 5g services.
Is there anything I can do about this or is it because it is an overseas phone?
Thanks,
Has boost activated the 5g trial on your service? You should have got a text.
Next is where is the closest telstra 5G tower near you? Do they use any of the NR band your phone support? From https://whirlpool.net.au/wiki/mobile_phone_frequencies you need them to use the band 78 which based on GSMArena your phone supports
