FREAKIN PROBLEM!! urgent help, pls!

Last nite my phone was fine, but it needed some juice so i recharged the battery over night! this morning i woke and saw that the phone couldn't get any signal, even though theres lots of signal, normally! what the fuck can be the problem? this really stinks!! the phone just lay still all night, it wasn't dropped or anything! i have a n3650!

thanks in advance, please help!

normally, you just have to turn it off and back on....but you must've done that already, right?

yeah... i've done that! it's wicked...

call up the network operator , perhaps they closed all networks 4 upgrading or sth....
