Chinagram is bringing in more issues :-)

Who will activate the context? The app itself or will it be always on?

For MMS when using two contexts, the MMS context has a MessageProxy defined
and network manager adds a host route to be able to download or upload an
MMS; how will this be defined for the app?

Will this context be editable by the user through the future UI to be?

I'm not contradicting, just expanding ;-)
