I’m planning a trip to Yosemite in mid-April. I was just wondering if my cell phone will work in the valley.
Well the answer is a definite maybe. I have a GSM phone through Cingular and I can’t get signal after Groveland or Mariposa or Oakhurst. Non-GSM phones,if you have one from about 4 years ago and it still works, tend to work in the Valley and even some ways up the Tioga Road.
If you have a wifi enabled Palm or a laptop you’re in luck though, the Ahwahnee and Yosemite Lodge both have wifi now so you can always check your email.
Good luck and have a great trip.
