SIM508 is not supported anymore. Use SIM548C is the best available now.

I have used SIM548C for my applications. It's good.

I need sirfII gps, I don't think that SIM548C is sirfIII

SIM508, SIM548C both use sirfIII You can see their specs ^^

I think sim548 can use sirf binary protocol to communicate but is not a sirfIII processor.

I don't think that SIMCOM do not use SIRFIII in their products when they say in the specs they do use it.
As I've known, SIMCOM & WAVECOME is the only 2 companies produce GPRS modules. So, SIMCOM is a big one, anyway
