Pretty sure I am getting my first 1 star

I do shipt in Michigan, I do Meijer only and I live close by it but this area is NOTORIOUS FOR not having signal. I had two orders today and I felt like I was running late and I thought my navigation would load on my way there AND GUESS WHAT IT DIDNT so I made a blind drive and one of the customer was like where are you going and why are you stopping 3-4 times and I'm like I am desperate of getting signal... that's why 🥲 i had to stop at in front of my apt to get the navigation loading. He was literally screaming in my messages by the time I delivered and I didn't even feel safe delivering the stuff but I did and I apologize for it. Does anyone go through this in Michigan???? I also switch phone carriers too and I still have really bad signal.
