I'm sorry,there is maybe a thread with similar topic,but I couldn't find it 😕 my problem is that even my APNs are correct (i manually imported them from the site of my network provider),when I turn on mobile data traffic (and i'm registered on 3g network of my provider) nothing happens...no network connection,no 3G or gprs,and mms doesn't work either o.O and i recently changed my SIM card,but the problem is still here

anyone have a clue what's the problem?

Do you have a micro SIM card or a Nano SIM card?

Do you have any taskillers, antivirus, or battery apps?

I have micro Sim card...lookout antivirus,and from those ''killers'' i have app cache cleaner..no batery saver

Uliwooly

uninstall all antivirus, battery apps, task killer apps > restart your phone and check again

if that doesn't work then repair your phone with SUS then do NOT install any app just enter the APN settings and check your data

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

You can also boot on safe mode

Problem remains after uninstalling all those apps,and also in safe mode...

Now only repairing with SUS remains...

I came up with an idea that maybe the problem is in phone itslef...in internet drivers or something similar..but its highly unlikely,cuz wireless is working.. and this is after all a smart phone, they are all about internet connection..
