Hi,

I have two 4G LTE devices, one can connect to 4G network, one could
not and has following error from connman log file:

Failed to change property: /ubloxqmi_0/context1
org.ofono.ConnectionContext.Active: org.ofono.Error.AttachInProgress
GPRS Attach is in progress

Does the error indicate the SIM is not activated? Or what could be the problem?

Thank you.

Kind regards,
