hi,
yes possible use gprs shiels pi. however, need level converter serial port signals , optional power pin (d9 on shield). pins on pi 3.3v , pins on shield 5v. can supply power level converter gpio connector. works fine https://www.sparkfun.com/products/12009
, best provide 5v shield directly. in cases shield can use pretty power (>150ma).
commands @ modem style , documented. should no problem. have tested sim900a module (http://www.ebay.com/itm/new-sim900a-ext ... 1209981501) , worked fine.
