As you can see my HL7802 support GSM Digital Cellular Systems(2G) and E-UTRAN (LTE) but I don’t know why when I try to put the module on LTE network the registration is denied (look to the creg value). The 2G network works well. I use the lastes firmware version for the HL7802. Can someone help me please ? Best regards
that did not mean it works in LTE mode
Have you put into another brand of LTE-M module to prove it can work?
Or have you tried with a working LTE-M SIM card to make sure the module has no problem?
