i am working on a project that requires me to send an SMS to 8051 micro controller,i want use USB modem from huawei model E160E,HSDPA USB stick,is there any way i can achieve this with out using the computer for interfacing
if you need help me with circuity diagram, you are already lost.
sinmce you ask this I see a need to tell you "a wire/trace is not a wire" it is a series of inductors with capacitors liberally spread along it.
if you do a willy-nilly layout (or even worse a "flying lead circuit") it will not work.

It would certainly be possible to fling together a GPS module, low-end 8051, and GSM Modem using "flying leads" and have it "work" (sic) - it can all be done with low-speed RS232 (or logic-level equivalent)...
eg, look at the photos here: msmvps.com/.../SerialPort-_2800_RS_2D00_232-Serial-COM-Port_2900_-in-C_2300_-.NET.aspx
