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.

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

My question
is, is this MSC number, visible from the mobile phone
side? If yes, somebody could actually wardrive, to get the MSC
number-to-location mapping?
Can airprobe, or OpenBTS help?
Creating the {MSC -> location} mapping database would be a very
worthwhile exercise. The data collection would have to happen from
phones. Either we create an application for one of the popular phone
platforms (Symbian, Android, iPhone). Anybody on the list knows if
these phones expose the MSC number to application software?
