I just bought a Botletics SIM7000 LTE CAT-M1/NB-IoT + GPS Shield Kit, installed the library Botletics_SIMCom_Library_v1.1.0 and was running the arduino LTE_demo code. Everything seems to work ok but I noticed when I send a SMS it says failed, but I do receive the message on my phone. Was wondering why the code thinks it failed ?
