Hi Aleksander,
Some more info... from a clean start, I used the AT interface to show that its registered and attached on primary PDN. I can ping the UE from the LTE side (Sierra cards respond to pings from LTE side when there is no data link).
Then ran the --attach-packet-service command and it times out as before.
cheers,
Chris

Could just be that the modem is initializing the SIM card and that takes some time?
Does the command timeout if you wait some time (e.g. 1 min) between powering the module+sim and running that command?
Does the command timeout if you send other commands before (e.g.
querying capabilities)?
