I've bought this phone about 5/6 months ago...it was good like first few months, then suddenly i faced a serious problem last month,my phone just stopped showing mobile network,my SIM card shows but it doesn't show any mobile network, whenever i dial a number to call someone it alwz shows mobile network not available,i don't know what's going on in my phone,but I'm really worried about it, I don't even know why did it happened,i did everything to fix it,as a last hope i tried factory reset,but it didn't work,still no cellular network, this thing is panicking me,i can't use my phone to call people,i can't use Mobile data while i go out... Please help me, please tell me how it you'll get solved,tell me why did this happen,and please let me know how can i fix it....
