Hey All
I'm trying to build an Arduino GPS tracker. However ever since I instialled the GPS module alongside the Sim900 shield on:

I can no longer get any connections to networks!!!

I tried the code provided by Arduino GSM to test for network connections from here https://www.arduino.cc/en/Main/ArduinoGSMShield.

However this is what I get from my serial monitor:

It looks like I had connection at the start and then there is none.
