I’ve seen people claim they have gotten a call on a M, T, W, and F. I’ve read that they usually call between 5-9pm (some saying 6-9pm) and then there’s other people like yesterday and today who got calls in the AM/early PM. And lastly I’ve heard the call showed up in caller ID as “MI State Univ” (an iPhone). East Lansing area code is 517 fyi. And if you don’t answer they leave a voicemail with your acceptance so don’t panic if you missed it, but I’m sure we’d all prefer to have that phone call conversation.
Hope this helps!
