I want to ask my friend to call me when when he wakes up (or when he will wake up?) today. Now, my question is what kind of conditional sentence (zero, 1st, 2nd, 3rd) I have to use in such case, if any, or maybe it is not conditional at all when it starts with "when"?
"When you wake-up, please call me"? (present simple)
"When you will wake-up, please call me" (future simple)
"When you are waking-up, please call me" (present continuous)
