It doesn't surprise John much that she can't reach Lionel; he hadn't had any reception in the car either and the more he takes in his surroundings, the more he realizes he either having an incredibly detailed hallucination -- which is not out of the realm of possibility -- or he's been taken somewhere else in his unconscious state. The woman in front of him is slight, not nearly strong enough to have carried him and he doesn't detect any dishonesty in her voice or the way she's looking at him, but he's admittedly not at his best.

A shiver races through him, followed by another, and he knows that's a good sign, if he's shivering, the hypothermia isn't as bad as he might have thought, but the contracting of his muscles drives pain deeper into his shoulder and he grits his teeth, jaw tensing for a moment. He doesn't want to lie back down, doesn't want to put himself in that position when he might need to drag himself to his feet at any given moment, but the pain is immense and for a moment he wants to close his eyes against it.

"My phone isn't getting reception, but yours is." It isn't a question, she's already offered to call help for him. "Who are you? Where are we?"

And who brought him here? John doesn't think he was unconscious long enough to be taken far enough that the snow would be gone, but he'd been hallucinating Carter for what felt like hours, so he can't be certain of anything.
