I'd usually ask a hotel receptionist for a wake-up call.
If you ask for a morning call in Pennsylvania, you'll probably get a newspaper.

Koreans use the expression "morning call" for "wake-up call ", but I think it's a wrong usage, do native speakers ever use it?
M : Thanks. Oh, has there been a phone call for me?
W : Yes, there’s a message for you. Here it is.
M : Thanks. One last thing. Can you give me a wake-up call at 5:30 a.m.?
W : That’ll be no problem.
I have heard it used, but not often.
