Xfinity Mobile eSIM Activation Issue – Calls Not Working / “Unknown Number”

Hello,

I’m trying to activate the free Xfinity Mobile line included with my Xfinity Internet promotion, but the line appears only partially activated.

Device: Samsung Galaxy S21+

SIM Type: eSIM

Current issue:

  • The eSIM downloaded successfully.
  • The phone shows signal.
  • Some texts were received during activation.
  • However, I cannot make or receive calls.
  • In Settings → About Phone → SIM Status, the phone number shows as “Unknown number.”

Troubleshooting already completed:

  • Reset mobile network settings
  • Restarted the phone
  • Xfinity support attempted a network reset on their end
  • Verified the eSIM installed successfully

Because the number shows as unknown, it seems like the MSISDN/voice provisioning may not have attached properly to the eSIM profile.

Could someone please:

  1. Check whether the line is fully provisioned on the backend
  2. Rebind the phone number to the SIM/eSIM
  3. Reprovision voice/VoLTE services if needed
  4. Reissue the eSIM activation if the profile is corrupted

If eSIM provisioning cannot be corrected, I’m also open to switching the line to a physical SIM card for the device.

Thank you for your help.

I pretty much have the same issues and the same phone. Except I cannot receive/send texts or calls. I have spent hours on the phone with tech support and made trips to my local Xfinity store. I have bars My phone says Xfinity Mobile but my number does not show up on the e SIM or the physical card SIM. I have contacted my previous carrier, Samsung, a Samsung repair shop, and Xfinity more times than I can count... No change
