Samsung c100:limited service

[The Razor]

PLs everyone I need solutions for a samsung c100 which shows 'limited service'permanently.
Sometimes it shows " no service" also and at all these times neither can it be used to make nor receive a call !!!
This problem stops temporarily after the pcb is heated. WHAT SHALL I DO ANYBODY !!!!!!!
I WILL BE GLAD!!
