excellent!!!! thank you very much!!

Sir when you mentioned the gsm module has it own supply ... does it mean the project will have 2 wall plugs or I can use a jumper connected after the regulator (5v) and connect to the gsm module ?

[@user-cf2by6no6k]

Hello sir, please how were you able to receive messages on the phone? Wa the SIM CARD defined in Arduino code different from the SIM CARD inserted? Because removing the same SIM to insert into the Arduino Connected GSM module means I have an empty phone with no SIM CARD and I will not be able to receive messages on this phone. Please I need your clarification❤. Thanks
