HTC10- AT&T - How to show number when calling and Advanced Messaging enable

[Android Central Question]

Hello,

I have the HTC 10 running on the AT&T network. Two questions please:

1) When I call someone, it always shows up private. Is there ANY way to fix this or a workaround? I'm wondering if the 7.0 firmware broke this.

2) Is there anyway to allow Advanced Messaging so I can send attachments over 1mb via sms?

Info for phone:
Android Version 7.0
Software number: 2.51.617.32

Thank you,
