r320sc unable to connect to mobile network
 

when my r320sc is switched on ...it shows connected but still i am unable to make or receive calls.
few minutes later it displays "NO ACCESS" line on the screen.

could anybody tell me what could be the problem.

did anyone get any answer for the question about ranenitin1 as i m facing a similar problem with the same handset of mine

Change the RF 11033 !

I'm also having the same problem with my R380 World phone but mine displays "Emergency Call Only". edemy2001, can you clarify your response.

Dear pbzmag, Have you any indikator for UHF field? Measure you, when power the GSM on, have UHF emiting. If no emiting, change Power Amplifier (PA) or Antena Switch ! If emiting is not continual change receiver (RF) chip. Excuse my bad english.

Regard's edemy2001 !

If you're reguarding the UHF field as the blinking light, then I would have to say that I have a blinking yellow light. The phone says my provider name, which is cingular, but does not send or recieve voice or data. However, the phone works with another provider such as AT&T.

Give me you e-mail. I sent sheme of indicator!

it is either from PA or RF IC 11033...most of the time these chips are the only thing faulty.....

edemy2001 - Sent you a PM.

syed - How much does it cost to replace one of those and how hard is it to replace?

hi there....
 

Is it possible for me to do the change of the PA or RF chip with my electronics background?.....

I can't give you more information about the PA and RF chips!

You need hot air station to change RF and PA!
