9160-DK connected once but could not reconnect

[paul_tanner]

usingnrf-9160dk and iBasis SIM with pre-built asset tracker app (2020-10-30_5522ca2b) and nrfCloud

First time the device was registered data transmission worked.

Now  just loops:

```

Connecting to LTE network.[0m[00:36:00.545,349] [0m
<inf> asset_tracker: This may take several minutes.[0m[00:36:00.552,398] [1;31m
<err> asset_tracker: LTE link could not be established.[0m[00:36:00.560,028] [1;33m
<wrn> asset_tracker: Failed to establish LTE connection.[0m[00:36:00.567,749] [1;33m
<wrn> asset_tracker: Will retry in 480 seconds

```

So i tried to delete device and SIM so I could reconnect.

After a few attempts I got the SIM re-activated.  Restarted the asset tracker app.

I get LED3 flashing and ...

```

```

Hello,

 

First time the device was registered data transmission worked.

 Did it stop working right after the first time? Did you do anything in the meantime, like changing project configuration or location, SIM, HW, etc.?
