I am trying to do a project with Arduino. It's an alarm that sends a message when movement is detected. I am using sim900a module. I live in Europe and the module is configured to the firmware to support European sim cards. Last week I managed to send an sms and today when i tried again the module cannot find a network. Led light on the module is blinking fast and it tries to restart but never finds a network. It is the same sim card and i didn't remove anything from the code or hardware. Plz help :(.
Connect this to that and point it that away while standing on one foot.
That is about the best I can do with the information you gave us. If you posted an annotated schematic showing how you connected your hardware items showing all connections, power sources, etc and your code would help us help you.

Sorry, im new to all of this, I will send how i connected everything.
Do it in schematic form if you can. If you need CAD software KiCad is full featured and free for the downloading. It is not a 1 evening learn.
From the same location? The SIM900 is a 2G device and there aren't too many services supporting 2G these days - hence the drop in price.....
Yea I did it from the same place. T-mobile Croatia still supports 2G.
