My wifes phone has been all week with out signal. I have the same phone with no problems. Under settings it shows as radio being off and not connected to network. When you try to make a call it says unable to call and make sure Airplane Mode is off... Already took to Kiosk and they tried the code which registers on network and nothing. Phone was also reset factory and nothing. Sim removed and replaced and nothing. Is there a code for hidden menu to reset cell radio antenna? Or is there a work around?
