Hey guys, i bought a sm-g900f unlocked and regognized that everything except 3g is working. I tried allready to find a solution with cdma workshop but I have to less experience with it.
I can use gsm and lte were it's strong enough,
but in the most regions in our country is 3g,
so I can't use the phone most of the time,
no phone calls or internet,
looking for your help.

best regards
