We'd love to help you reconnect back to the network! There are several troubleshooting options we'd like for you to try. The first one involves resetting your network settings, which will be the seventh step on this page. This options resets Wi-Fi networks and passwords, cellular settings, and VPN/APN settings. Be sure to document/save your passwords before doing this.
You can also use our Troubleshoot & Resolve tool as well. You'll need to select your device to begin. Once you've done that, you can select Phone calls or Messaging beneath Service/network issues. We look forward to hearing back from you!
