can sombody help me get the modding code for my song ericsson w900

i have a sony ericsson w900 an am trying 2 get da modding code so that i could have a better signal so, can sombody help me please !!

 

The code you are after enables EFR (Enhanced Full Rate) and while it can help increase the signal it generally doesn't make much difference.

The codes are operator specific, for example the O2 UK code for this is *3370# although most people wont notice the effect anyway!

 

so der no other code tat i could put n my phone so that i could have signal like a normal phone ??
