AFAIK Connman is not supposed to deal with cellular interface directly,
but delegate this task to ofono.
Perhaps you can give it a try, ofono is also supposed to deal with AT command.
Don't know if your modem is supported.
Please also post on pastebin or whatever the output of connmand with
debug enabled.
$ connmand -nd

Julien
