MC75i in Brazil | Thales IoT Developer Community

May 18, 2018 - 8:50am, 2148 views

I have MC75i modules in the field for years. Worldwide. But now customer in Brazil can not send data. The problem is that modem after power up sends +CREG: 0,2 for more than a minute or  even +CREG: 0,0. They tested several operators, none is working. Also, they tested SIM cards in mobile phone - it was able to work. 

Can you advice what should be wrong? Thank you.
