Hi, I am using BSNL EVDO datacard of micromax mmx 300C with REV A Technology.i want to know if i purchase a REV-B datacard which has been released from MTS and the MODELS ARE ZTE-AC2791 or Huawei EC306. will my same CDMA sim of BSNL work in that datacard as i think REV A and REV B is different.i am in search of unlocked REV B datacards also.if Anyone has tested pls give a solution. thankyou
