This is incredibly aggravating. I am in city limits and can be under a tower and I will not have cell phone service or access to cellular internet. Ever since I upgraded to the 15 this has been nonstop problematic. I am about to drop verizon and iphone all together after being a life long customer. I have gone to multiple verizon stores and there is never a correction but instead that "towers are down" when they are simply not and other family devices are working successfully that are not as new devices. 15 Max is the culprit to connect with Verizon and I want a resolve. I am paying for nothing.
