oFono was able to register on the network an activate the context. This
part is interesting for you:

Do you still run the oFono scripts? From the logs it looks like connman
is trying to activate an already active context.


As a side note, oFono and ConnMan have persistent states for services and
contexts. They are stored under /var/lib/ofono|connman. When debugging I
found it useful sometimes to start with a clean state.
