I want to get details about the AT&T cell phone coverage map in California. The service provider has said very strong network service in the city, but a lot of people are dropping AT&T due to poor network coverage. So I have decided to gather more information about the AT&T cell phone coverage map rather visiting any websites. Please share your experience with AT&T network whatever you have come across. Here, I am willing to go with the network service because of its pocket friendly plans. So, before I get the service, please stop me if it has very poor cell phone coverage in California.
