I have successfully sent text to a friend with an AT&T phone and also to Google phone & text using a Hologram SIM but I can't send to my Verizon phone because Hologram uses +882 as an area code and Verizon blocks all messages from this code.
I purchased and activated an AT&T SIM which appears to work on the serial monitor but nothing shows up on my phone. Has anyone had luck with this combination?
