yes, but note that mobile phone base stations are not battery backed up like a traditional land line either, so they too go out after a very short time, just a few hours typically, in a power cut.
In a very local power cut it is not of course the outbound calls that are the problem, as the mobile handset can stay switched off to conserve battery until need to use it arises, so long as it boots quickly when required.
The harder problem is the receipt of incoming calls, as like radio the receiver has to be on all the time just in case - which is really a giant leap backwards. I really do not see why a lower power fibre monitor could not have been developed for low bandwidth emergency signalling, it could also have been the mode to fall back to when there is no traffic, making the whole network much 'greener' into the bargain.
It is not insoluble, but there is a bit of a head in sand attitude in some quarters.
