So i have this old s3 docomo that i buy from a friend.
I use non Docomo Simcard and its work i think the phone is already been unlocked before.
But it wont detect any 3g or 4g signal.
Its only detect 2G.
Yes my area has both 3G and 4G signal.
Can anyone help me? i've been searching for the tutorial but i cant find it.
Thanks in advance.
