Last week I ordered and received two 4G modules with the following Serial ID: #6C4167057C10548E: everything works fine #583567057C1054FE: problem in sending and receiving SMS Today I started testing them and by reading temperature and leaf wetness sensors everything works fine. Unfortunately there is a problem in sending and receiving SMS with the one with Serial ID: 583567057C1054FE. I uploaded the two examples: _4G_04_sending_sms and _4G_05_receiving_sms and I got an error like: “2.1. Error calling ‘configureSMS’ function.” With the same SIM and the module 6C4167057C10548E everything works fine! May I ask you to give your support on this issue?
Any help will be apprecited.
I didn’t find the right solution from the Internet.
