The ATT coverage map for the 77404 zip code is absolutely fraudlent. I have property in Sargent, TX and the ATT Cellular reception is non existent. Their coverage map shows coverage there but myself and other ATT customers do not get reception. ATT is aware of this but continues to give lip service that their map shows coverage. They are more than willing to sell you cellular service but do not support it. I do not know may time I have spoken to customer service and they continue to say their map show service and I should be able to use my phone there. I have told them numerous times that I would not be calling customer service if I got service.
