The nature of the storm, the Surgespace is that it’s physically the peak example of the instability that can occur when you mesh our space, with that of the Outside. Isaac is far more of an expert on the material than I am, so it’s a shame we can’t consult him for this, but I believe that, if some semblance of the phone still exists and is detectable from beyond the reach of the storm, then she may be too. No guarantees of course.

There's still the problem of getting the signal into Existence unless it's right on the very edge.
