I happen to know the carrier in that area. Actually I'm not sure about
the GSM coverage provider, but I think that AT&T has GSM in Yosemite
Valley, unless Golden State Cellular put in some GSM service. There is
no GSM on the way into the park on 120, once you get past Oakdale; it's
CDMA and AMPS only.
