This does sound frustrating to deal with not being able to connect to your service outside Wi-Fi. We appreciate you sharing this concern with us. We have a few things for you to try to see if we can fix this matter in the settings. If not, Service would be the next option. Check out the link here. I understand some of you have attempted the troubleshooting steps. If they do not work, there is a link to contact a service center. If any of you have any further questions. Feel free to send one of the moderators a private message. You can do that by clicking on our profile and selecting "Send Private Message."
