Why cant I connect to the network especially 4G
My Xiaomi MI4A cannot connect to 4G network.
When i first bought the phone it (4G network) worked perfectly but now it is forever on edge (E). how do I activate 4G network on my Xiaomi MI4A cell phone?
I've turned it on and off many times, I've rebooted it many times too, I've dialed *#*#64663#*#* and it also doesn't work, all in the effort to try and fix my network problem.
Is this a good question?
