With a GSM module, you want a pre-approved module so you only need to do EMC testing. Doing your own radio testing is ridiculous and expensive. For RoHS compliance you should be able to get away with a declaration as long as not only the components but also the assembly process is lead-free. Incidentally, I have some thoughts on fixing this process, if you'd be willing to talk about it. Contact me on IRC (Kliment on the freenode network) or at kliment at 0xfb.com (yes, that is a zero)
