Question about why all my calls keep saying UNKNOWN?

[GTAmissions1]

I find it strange that I recieved two called at 8:49 PM yesterday and another one a minute later. What makes it strange is that I don't know if the caller is in my phone book or not. I am using the HTC Evo 3D. Should I call back or should I buy caller ID and voicemail just incase for next time?

When I add or remove a feature, will it affect my contract or changing the My 10 promo plan affects the contract?

It says unknown becuase you do not have call or name display. If you buy it & add it on your plan it will NOT affect your plan what so ever. Its a add on. Its not change your 10plan at all. It just adds call /name display.

Nope it does not affect your contract at all. It just adds the name / call display on yuor current contract agreement.

Thanks for the solution. I'll be sure to purchase the value pack that includes name and call display.

how are we still paying for caller id? that's just as ridiculous as still having to pay for text messaging
