GPRS module for Arduino

Hi All!

Libelium sells this GPRS module for Arduino

www.libelium.com/tienda/catalog/product_info.php?cPath=21&products_id=59

Does anyone know what's the maximum throughput of messages with this shield i.e. how long does it take to send or read a message from GSM module?

I was thinking to replace a SMS GW (which now ties up a computer and a few handsets) with this but the system should be capable of sending / receiving a few thousand messages per hour.

Do you need a cell phone plane to use one of these? I am guessing that you get a plan and take out the SIM card and stick it. Is that correct?

Thanks

Yes, you will need a SIM card to use this shield.

I ordered two units from Libelium a few days back - haven't heard of them since. I can post test results when they arrive.
