    Problems with SIM300 as it doesn't detect the sim card

    sim 3000 gsm module The sim300 module work fine with sim-cards of 2.8 - 3.0 vol. But don´t work with the sim-cards of 1,8 vol. My test board has all fine. It has the capacitors of 0.22 uF, also the TVS and the resitor pull up between VDD_SIM and DATA_SIM (10K). I do not see the problem.
