Nearly every modern horror film has to find a way to make cell phones unavailable. Countless older films would be ruined had cell phone technology existed at the time. This is just a basic fundamental thing screenwriters have to get around right off the bat. Too far out in the wilderness, oops phones were destroyed, oh no we forgot them, massive power outage, etc. etc. etc.
shareThe scene in the cafeteria makes it clear their phones were left in the locked car.
Though it's likely there wouldn't have been a tower or signal near there anyway. It didn't exactly look like a fashionable resort.
You might very well think that. I couldn't possibly comment.
I thought that was odd too. I know they left them in their car or locker, but yeah skiing with cell phones isn't by any means uncommon. Good to have in an emergency if someone gets hurt.

As mentioned, in 2010 a ski resort would not have cell reception. I'm sure there may have been exceptions to this rule. I am sure one person can manage to name one mountain they'd have been able to get reception on. But, in most cases as cell phone would have been useless as far as contacting help.
Also, besides the fact that they specifically mention wanting to have a cell phone free weekend (you know, getting away from it all). People who ski do leave the phones in their lockers or cars simply because they're so easy to lose or have get broken. Cell phones are expensive.
