    @malwww, with the integrated USART i don't need them, because PIC and GSM works on the "same" signal voltage.

    I tried the pull up without the "amp" but the GSM voltage is to low, and the PIC won't them recognize again!

    I have no more ideas, helpppp!!

    So lower the voltage your PIC is operating on. The data sheet says the PIC you have selected will operate on voltages from 2.0 to 5.5 volts
