Yes, the answer is: No. The phone does not know about this.
It would have to be a service that incorporates a user or mobile
phone software based part that knows about the location and a network
based part that can perform a SMS routing request. Both of these would
have to be correlated.
The implementation of this in a way that honors privacy as well as
security is left as an exercise to the reader.
This is most certainly not a task within the scope of osmocom-bb.
cheers,

p.s. the relevant cell specific information that is known to the phone
can be found in the first seven fields e.g. here:
