Came thru as Private Number, but Show Caller app displayed phone number. As phone got to ear heard beep that call had ended.
This # called my mobile, left no message. Has same first six digits as my mobile.
"I cannot reach you. Please call me urgent on same number 520 274 810 204 Grant." Google transcription from voicemail. Listening to it I think it gave the number then said for your grant. Not sure exactly the end of the message.
