========================================
I just got new sim card and my old phone s20 ultra beats this phone mobile network speeds by huge marginal!
I have tried to same server for each phone and s20 ultra got nearly 3 times better score with this sim card. Is there something I could do to improve result. Even YouTube struggles to work on mobile network
Also my old sim card worked fine with this phone but not this new one..
