Ok, I was having connectivity issues and notification issues with my iphone 8 and 11. The notification issues seem to be stemming from my apple watch. No notifications on my phone even when my watch was left at home. I took the watch off my mobile plan and sold it. MOST, but not all notifications are now coming through my phone again. Next up is my data connectivity. I have been having constant call drops, no data service in various locations etc. I am moving our family to a new service provider that is 1/3 the cost of our current provider. They only have 3g service. I turned my 11's radios to 3g only and my connectivity issues went away. Is this a problem with hardware? as my samsung has no issue with LTE service anywhere, but my iphone loses signal and becomes useless even in places the samsung is showing full bars. Sounds like a hardware issue to me.
