Why has my number turned into a private number?

[AC Question]

why my number turned into private number?

I was playing Fairy Farm In my Samsung Galaxy S3 Mini. Suddenly it hanged and then I turned off my phone and again turned on. I called my husband and he said it was showing as private number. Why is it? I again turned it off and again turned it on then it was ok. why this happened?

The game evidently has a bug that affects the phone app.
