Nov 25, 2015 · SIM800 is one of the most commonly used GSM module among hobbyists and Arduino community. Even though AT command reference is available with a quick Google search, it is not very easy for a beginner to properly understand and use Arduino with SIM800. Actually the SIM800 should not be supplied with more than 4.4 V according to the datasheet. I would be interested to know how this problem was resolved. I have a similar problem. I cannot get the SIM800 to connect to Three or the O2 network even though both SIMs work in my mobile phone. SIM800 gsm Module returns 0 on AT+COPS? Ask Question ... AT OK AT+CSQ +CSQ: ...
