I'm more interested to know why you need to pay for fibre cable problem

at 1st i'm using their MC888 but because the place i'm staying cannot receive strong 5G signal
so i bought my own that has snapdragon chip inside and that really boost the 5G signal
if your place can get full bar using low end chip, u don't really need to get your own router

so the speed not only depends on your signal, it depends on your chip the device is using
so your phone is what phone and using what chipset inside?

what did you buy?
