Telephone

“I am getting a call in my cell phone. Mr. Raman is on the line.”
Are the prepositions in these sentences OK?

“a call on my cell phone”

The others are OK.

  1. He’s out to/for lunch.
  2. Could you please have him call me back?
  3. He just stepped away.
  4. When are you having the meeting?
  5. We’re planning on having the meeting around noon.
    Please correct all the above and comment.
  1. would usually be used in conjunction with a noun ‘He just stepped away from the desk’. Otherwise, it should be ‘He just stepped out’.
    The others are okay.
