I am from india and Ten months ago i bought an unlocked sprint note 3 from ebay. To my surprise it dropped signal to the best. After lot of hard work I came to know that it's radio frequency is GSM 850(I hope so I found the right problem) and that's the culprit. That's why when I switch on data services phone gets passionately hot, network loss to no network at times and then again I get the network and all .. So now I want to know what can I do regarding that
