We are getting the Inland Cellular operator when we try to make a phone call out of the city limits and in some of the smaller towns around us. We get a message that our phone are not registered on their system. According to the Verizon map we were in the Extended 4G coverage area. I talked to the Inland Cellular operator and they said I needed to talk with Straight Talk to resolve the issue. I call Straight Talk and they say since I have a BYOP it is my problem. We have a Samsung S3 and S5, Has anyone else had this issue after moving their Verizon Phones to Straight Talk
