I will give you my expert , I was working very near to the GSM tower ( near 25 meter ) and to be sure of my thoughts about Tx or power off , I was bridging the Power amplefire's (900Mhz) input to output , ofcorse after raising of the chip ( there is no PA there ) , then phone works normally .
that was for testing because PA is the Tx amplefire without it work will be nonconvinient !

Bridge pins of the PA 4 to 21 / and 5 to 14 . without the presense of PA chip .
I'm not sure from results of 1800Mhz bandwidth.
