Need to check IMEI on Xfinity's side

Hi, I recently bought two unlocked Samsung Galaxy S25 phones. One phone was an breeze to upgrade/swap out on my account. The second phone came up as incompatible. I did put out a ticket out to the vendor I bought the phones from, but they asked me to double check the IMEI with Xfinity support. The chat bot on Xfinity has not been helpful, and just sends me in circles. I need an Xfinity employee to check this IMEI on Xfinity's end to see what it says.

Thank you for your time!
