BYOB - Samsung Galaxy s21

I have a Samsung Galaxy s21 I have been trying to activate on my current Xfinity Mobile account. Xfinity BYOD IMEI checker states that the phone is not compatible even though this is a phone they sell and it was from Verizon so it is using the same technology since Xfinity Mobile uses Verizon's cell towers. Can anyone explain why a phone isn't compatible with Xfinity Mobile? Because no one at Xfinity can explain it to me - not via chat, phone, or in-store..

The phone does work for a few days before Xfinity compares the SIM to the IMEI and shuts off my data and cellular. This is very frustrating because I know that the phone does work with their service. I understand I won't get customer service if I have issues with the phone - I just want the service to remain active as it does for the first few days. I did search the forum before making this post and there were a few threads about this same issue when the phone was first released but I didn't see much in the way of a resolution.

  • "I know this is confusing, this work kind of like this: Your current device Samsung S21 has been designed to work in the channel number 10024, this channel may be the same than many other providers but Xfinity Mobile devices work on channel 360081 so then, that is why your device is not compatible even though it is the same model that we sell. Being unlocked doesn`t mean that will work with all the carriers."

  • "1)  They needed to rebuild my account, which means your cell service will be inactive if and while they do so for you, make sure to call from another line, Skype from a PC, anything but from your mobile service on your new or old device.

    2) Tell them you need to add a new unlocked S21, but the system doesn't recognise it and says it's unsupported. It's brand new direct from Samsung, and Xfinity has already said it's supported.  This needs to go through tier 2, make sure you either get through to them, or the agent talks to them.  Some of the tier 1 agents just waste time and you get nowhere.

    3) Since they're going to be removing any information on your new phone, including the paired information if you managed to at least pair it, make sure to reiterate the model exactly, and the IMEI.  First attempt put a S21 Ultra in the system with my S10+ IMEI, second time got the right IMEI, but as a S21+ instead and they didn't set it active, so after a few minutes, that one was gone.  Last call removed the pair, added the device correctly, added an active line for it that gave me a new number, and then transferred my old number back to it.  I will be following up on this, since it still shows the new number online on my account, but the proper number is working for incoming calls.  I won't be completely satisfied until the online account syncs properly."

PS: I have reached out to Samsung and they have confirmed there is no hardware reason this phone wouldn't work on Xfinity Mobile's network. They informed me that this is 100% an Xfinity gatekeeping issue. They weren't helpful in fixing any software issue to code the phone in a way that is universally acceptable to all carriers or identify how Xfinity differentiates their s21s vs the competition's..

This is a terrible money grab by Xfinity to try and sell me a phone I do not need. I have a perfectly capable Samsung Galaxy s21 that does work on Xfinity Mobile because there is no difference between the phones Samsung makes.
