The modem is still in 'radio turned on' mode, e.g. online.  So as far as =

oFono is concerned, nothing has changed.

As to why your context activation fails, who knows.  oFono simply sends =

the command to the modem.  If the modem responds with an error, then you =

need to figure out why that happens.
