How do you work this thing?

So, last night H was looking for a phone number for some friends. We found it and H wrote it down in big numbers on a piece of paper.

He picked up his cell phone to call them and didn't know how to dial it. "What do I do? How do I use it?," he asked with a bit of tremble in his voice. "Oh, you just punch in the number like this," I said.

He punched in the number after a few tries and then decided it was too late to call them anway.

As it turns out, their phone number was in his contacts list, but he couldn't figure out how to find that contact entry either. He doesn't have to...all he has to do is say, "Call X" and it will dial. But he forgot that too.
