Hi all
I am trying to send an sms using arduino unko with lte shield.
It’s working fine with serial monitor but can I send a mesg by using switch I mean I Dnt know about sketch and if someone can send me a sketch for this will be very helpful
Thanks 
What cellular shield are you using?
LTE CAT M1/NB IOT
Looks like sparkfun has a guide for that. There’s no button in the example but you could modify the code to add one.
