Just like what title says, my x62 module cant connect to NSA network and its a growing problem with my other known RM520 users. LTE and SA modes works just fine. I also tried with different network providers, resetting it, upgrading its firmware version, all of the possible debugging steps, locking commands, and even transferring it to another board but still no avail. There was no special configuration and can confirm that I have a working 5G cell signal on my area since my other RM520 devices works with no problem with average -65 RSRP on NSA band. Any ideas on how to fix? Its becoming an alarming case here in PH.
Might help:
Checking if the module can scan the available NSA bands (it returns none):
LTE B1 + B3 + N41, sometimes it can support B1 + B41 + N41. Also this is not a country compatibility issue since my other RM520N-GL devices works fine. Its just these other RM520N-GL losing the capability to connect to NSA starting from last last week. Again, I did tests with my working RM520N-GL in the same location with the same configuration and still the bad ones doesn’t work. Cant pinpoint the actual cause of this.
Also it is worth noting that few weeks ago I had a similar issue where 5G could not be activated on my RM502Q-AE with whatever I did. What worked was powering off my router, taking the sim card out and put it inside a mobile phone that supports 5G. After that I put the sim card back in my 5G module and NSA 5G worked right away!
