  1. Hi There,


    Following problem:

    However i change the "STARTMODESCR", the module shutdown after 10s i turned it on with SIM Card inserted. With no information.


    Without the SIM Card it works properly.What could it be? I can’t figure it out… :/ The module reads card failure and shuts down?


    The SIM Card works fine in other devices such as mobile phones or something else.


    Thx for help

    1. Hi Simon, this is a tipical sign of an inproper power supply unable to withstand the higher current needed during network registration hence the shutdown.
