How is your nokia 7650 reception?

Hi guys - i noticed something with my mobiles reception - when i am in a region of no reception for a long period of time and then i go out to a region of good reception my mobile tends not to get it's reception back - i will have to restart it. Sometimes the network indicator is stuck to full - yet when i try to call i get no reception nothing.

I have set gprs when available and my network support gprs - and also i noticed that in certain areas even though i get some degree of reception the gprs icon has a slash across it, and in these areas when i try to call with mob i get some weak reception - the reception bar would be marking two or three bars.

Has anyone have the same problem - could it be the sim card?

i have had a similar prob with my 7650. I think it was caused by low memory, cos when i closed all running apps i got my reception back. i have recently removed all apps and reinstallesd them, i havent had a problem since.
