STUCK LTE Connection

nardoz-dev

Hi all, i have some problem while i try to estabilish an LTE connection . 

I'm using nordic n9160dk. 

I just search through the site, and i see a lot of topic like this, or like this, or  this .. but none of them resolve my issue .. 

This problem happen only with Pelion SIM, with others from different operator i don't have any kind of problem.


I'm using modem fw 1.3.5 with AssetTracker_v2, then i open LTE Link Monitor v2.0.4

This is what i got from LTE Link Monitor.

    Hello,

    the network is giving the error code ESM 29 (user authentication failed). This could be caused by a number of reasons so the best option is to contact Pelion support and ask why your device is being rejected. And if you still aren't able to identify the cause, you can capture a modem trace and upload it in this ticket.
