hearing pairing text alerts

Welcome to the Apple Support Communities!
I understand you are using ReSound hearing aids with your iPhone 6 and want to hear audible alerts for your text and email messages. Is your iPhone updated to the most recent iOS? Do you have one of the compatible ReSound models listed below? If so, when you set up your notifications for text and email on your iPhone, you should be hearing the audible sounds through your hearing aid. You may need to refer to your owner's manual for the device in addition to the resources below. I've highlighted some key information here for you. Click on the links for complete details.

Use notifications on your iPhone, iPad, and iPod touch​

To get notifications, connect to a Wi-Fi or cellular network. If you don't get notifications for a specific app, try these steps:

1. Make sure that the app supports notifications. Go to Settings > Notifications, select the app, and make sure that Notifications are turned on.
2. If you have notifications turned on for an app but you're not receiving alerts, you might have Banners turned off. Go to Settings > Notifications, turn on Show as Banners and choose a type of banner that you want to see.
3. Make sure that you’re signed in to your Apple ID. Go to Settings > iTunes & App Stores and enter your Apple ID and password.
4. Make sure that Do Not Disturb is turned off. Go to Settings > Do Not Disturb and turn it off. Or swipe up from the bottom of the screen to open Control Center and tap ​.
5. If you’ve recently installed an app or restored from a backup, open the app to start getting notifications.
