[QUOTE=henrylife;40611439]Did you try Settings -> More Settings -> Mobile networks -> Network mode, set it 4G only or auto connect.
Another workaround maybe there's problem with your apn's? For example I had it set to MMS then ahd EDGE available only.
Second warkaround is secret menu, type it in dialer *#0011#.[/QUOTE
