Network Problems!

\n\n3G not working! android 7.0, 2G works fine on 2G option only, if its set to auto 3g/2g or 4g/3g/2g it doesnt, I tried all APNs, network operators nothing worked. I got 4G ready sim. SOmetimes I got some 3G network but even changing the prefered network from 4G/3G/2G to 3G/2G wiped the 3G, and I couldnt get it back on. It seems it happened very randomly and for a brief period of time.

Please change Sim card to latest version as I don't see other solution. We don't have such issues.

How you updated your phone?
Did you perform factory reset after changing Firmware version?

I updated my phone right after I opened the package, via the automatic wireless method. I did several factory resets after the update, nothing worked, it even got worse. At a time the OS was just crashing and rebooting after 10sec of on time.... That problems seems to be gone by itself for now.
I need my 4G...

Interesting is that sometimes without doing anything 3g just appears, then after a phone restart it disappears. Then turning 2G only back to 3G/2G 3G appears for like a second.

I just mentioned that I got the 4g ready SIM, don't take me as an analfabet please. I changed my SIM just to try and solve this problem. None of the flashing methods and shit that was suggested works. When I downgraded my android to 6.0 again 3G worked flawlessly, every time I turned it on. Then back to 7.0 and there goes the 3G again. FIX IT NO EXCUSES                                                                                                                                                         For now I'm gonna stay with 6.0, 7 is obviously crap (battery life, charging time, network settings etc.)
