Thank you very much for that prompt and clarifications.
I have done my connections, things gone very well. I can display and manage my tempreture and humidity data. I setup an alarm also to work for the certain high level tempreture. But I am still unable to send an SMS msg from the logger by means of the GW-11 modem if there an alert on high tempreture. I couldnt programm that so far. Please advise your hints.
P.S GW-11 modem was recommanded by Pico agent in my country to be used for sms escalation process.
