I suppose it could be a matter of which *carrier*, of all Betamax
uses, is delivering your call to which mobile *network*, which could
change, specially the carrier part, randomly on a call by call basis.

I have experienced the absence and presence of caller ID, using both
Betamax, and other provider, with no apparent explanation. One of
these providers specifically told me they couldn't always assure
outgoing caller ID, because some of the carriers they used did not
suport that...
