Hi Sylvia. Which ZTE phone are you using? All phones shows who is calling if the number is saved in your contacts or if your carrier offers a caller ID feature. With minutes and days on the home page, tap and hold on an empty space of the home screen, there's usually a widget for that. With car Bluetooth, is the phone paired properly? Like is music playing on the car's speaker? With Roaming, have you activated the service?
