Have many of the same issues listed, I have went to Straight Talk, through the website, got a sim card from them, have one ATT phone I converted and one Verizon converted, they each cost 30 per month unlimited talk and text, (45 if you want data) so for $60 a month have coverage most everywhere.... seems one or the other usually work on the river, as they are using the parent towers, cust service is in the Philipines....which was the only reason my Att agent could give me to stay with them, no contract so actually little risk in trying for a month,
