Arduino based GSM Mobile Phone using SIM800L | Call & SMS

Sir, code mai Keypad.h library error batta raha hai......
Kya karu

Brother, how can it be modified with LCD display??

lcd with nano ka bhi bata digiye

Brother, please answer my question can we use 16*2 oled display instead of this 4 pin display

its seems like there's something wrong with the gsm_init(), the screen and probably the code too freezes when it gets to it.

When I run this code all it does is show text that reads "Arduino GSM Mobile", no buttons do anything.

Sir when receiving any call keypad A pushed but not received the call. What is the actual cause of that including received SMS. Please answer me.

Many many thanks Sir for your awesome projects. Excellent one , perfect coding.

it's so cool. I would like to have some notions in the field I also do electronics and robotics but I am training in Benin and I want to deepen my knowledge.
