Give College Board a Cell Phone Number - Yea or Nay?

My son is about to take his first CB test and I see that they ask if he wants to provide a cell phone number so they can send him texts. On the whole, have your kids found this helpful or annoying? He’s a sophomore, so I could also imagine that the answer is to wait until next year, that there won’t be anything useful now.

I don’t recall my son getting annoying texts. Maybe reminders of test dates? And there was one last-minute test day cancellation due to flooding.

Nay. I don’t see the point. There is nothing that urgent that needs to be conveyed by cell rather than email.
