Thanks for the answer, but unfortunately it didn't help me.

I figured out that the *at_cgdcont_cb() *callback is not called on 
reconnect:

_The correct log_ (on startup):

Jun 29 15:16:38 mx31tt01 daemon.warn connmand[561]: Skipping disconnect 
of /he910_0/context15, network is connecting.

Jun 29 15:16:38 mx31tt01 daemon.debug ofonod[657]:

_And the fail log _(on reconnect):

Jun 29 15:19:34 mx31tt01 daemon.debug ofonod[657]: 
gprs-context.c(240):at_gprs_activate_primary() cid 1
Jun 29 15:19:34 mx31tt01 daemon.info ofonod[657]: Modem: >

...

property: /he910_0/context15 org.ofono.ConnectionContext.Active:

causes include: the remote application did not send a reply, the mess

Any idea what could cause this?

Marko
