I'm certainly sorry to hear you're having this issue. I'm glad outgoing calls and SMS are working. Given those items are working, it sounds like you've signed in correctly, the line is listed as a line you can use, and the line is provisioned.
I appreciate you restarting the app. What about uninstalling and re-installing the app so that you have to sign back in?
Beyond that, if further troubleshooting is needed, I would recommend contacting our Beta support team at 1-844-889-5651 from 3:00 a.m. to 10:00 p.m. PST.
Hi there! I wanted to see if you're still having trouble. Were you able to uninstall/reinstall with any success, or have you reached out to our Beta support team? Please let us know how you solved this or whether you're still in need of assistance!
