1. You use ofono-1.24 which is fairly old. Latest release is 1.31 so
far.

2. Ofono is trying to communicate with your provider here and sending
ppp configuration requests. It does timeout several times. That means
your mobile provider is not answering this requests.
At some time you should receive something other than a "(TO+)".
If I should guess, I would say this is because of wrong apn settings.
