I bought an Arduino Uno R3 Board + SIM900 (GPRS Shield For arduino UNO) (I tried the same with iduino)
I connected them as i understood from the internet (Picture of the connection attached)
The simplest code i'm trying to run is modem checking but it doesnt return any imei,
and also when i send through the ide AT commands it doesnt respond at all.
Please guys its for my work and it really important for me, Please help me!!
Thank you all
