I am developing LTE-M application with IMS2 HDK from Avnet and using SIM Card from IoT Starter Kit.
I got connection problem. Sometimes it cannot get register to the network for whole day, but it sometimes works for few hours. When it can register, signal stength is good (AT+CSQ -> +CSQ: 19,99). Therefore, it is not likely caused by signal coverage issue.
Could I get technical advise here?
Thanks a lot for your help.
