My iPhone 7 says cellular issue and won’t update to latest version. I have Xfinity service
iPhone 7, iOS 15
Interesting. I do have that middle but didn’t it say after 4 years service was no longer supported.
i was finally able to get phone to update to 15.7.2. Hope that helps. Will see. Not sure about my service provider being much help. We are out of state and 5+ hours away from store. I will have to wait until I get home to further resolve should I need to

80% maximum capacity is not healthy and is to be expected in an older model such as iPhone 7. That original battery is likely to be the cause of your cellular issue – as the weak battery cannot supply sufficient power to the antenna to connect with cell tower signals. Have the aging battery replaced and all will (probably) be well:

marlynn ~ To be clearer, this icon is the Settings app:
...Tap it to open Settings app. Then scroll down to Battery and tap it. Then tap Battery Health and tell us what the Maximum Capacity % is. If its value is only "––", let us know that.

Battery shows 80% from when it was new. I was finally able to update to 15.7.2 NAs of now I have service. I’ve been to Apple store and they said I could not update but here I just did! I’m not sure if my problems are with Xfinity or not. It’s been a nightmare making call after call. Thank you for your response.

marlynn ~ iOS 15 is the latest version for iPhone 7. Does your iPhone 7 still have its original battery?
And what's the Maximum Capacity % here?...
