Guess it is very difficult to solder the Sim300 module. A connector is available for the same which is soldered on to the PCB and then the module is mounted over that. For more discussions about the module, have a look at this thread.
Its kinda bit difficult to solder the connector of SIM300 as its very fine n the spacing b/w the pins is too small. U hav to b either good in soldering or u should hav got a good pcb which repels the solder properly except in pads...

There is no PCB that repels solder. All you require is good soldering skill and the ability to solder smd components. The same soldering can be manually done with ease in 5 minutes. All depends on your practical skill and experience. Cheers
