Need to install app on my phone

You probably have to contact apple customer service because there might have been a dispute on a card and it might not let you download until you get it resolved. That is what happened to me before, and I didnt even order a service it was just a glitch. So i'd call apple customer support tomorrow about your app account on downloading apps.

A last attempt:

-Use any Internet browser to connect to any website. If nothing loads,

use another device on the same network to see if it can connect to any

website. If no other devices can access the Internet, turn off your

Wi-Fi router, then turn it on again to reset it. There will be a button on the back to hold for at least 30 seconds, and give it 5 minutes at least to reconnect. If you still can’t connect to your Wi-Fi network, contact your Internet provider for more

help. You may just have a bad router and your cable company will have to send you a new one OR there is just an outage in the area.

-If only your first device can’t connect to the Internet, get help with Wi-Fi on your iPhone, iPad, or iPod touch, Apple Watch, Apple TV, or Mac.

If you use cellular service to connect to the Internet on your iPhone or

iPad, make sure that you have cellular data turned on for the app that

you're using. To do this, open the Settings app, tap Cellular, then turn

on Cellular Data.

Hope this gives you more insight if the first one didn't help at all.

Cheers!
