Did you have to go into an Xfinity store? I’ve tried to add a second line but xfinity online says it can’t add my request with my own device.
It'll depend on when you catch them. If they're inundated with requests for SIM cards, you'll get a message saying you have to visit a store.
I was able to get them to send me a SIM after a few tries, and I added the Xfinity Mobile physical SIM to my XS Max that is using my main T-Mobile line as the eSIM and Primary.
I notice in my case that since Xfinity are a Verizon MVNO, I will very rarely but definitely see a coverage difference. Recently, my XS Max had three bars of Xfinity Mobile in a location where T-Mobile did not penetrate the building at all.
As a secondary line, especially if you're using eSIM as your main, I think Xfinity Mobile has a place.
But they are a little backwards with some things. For example, there is no support for Apple Watch cellular at all, which only makes sense because their goal is to keep you on Xfinity WiFi as much as possible, and they don't want to risk what they're paying Verizon by having you on Verizon cellular towers while you're hiking or running.
Xfinity Mobile has zero support for eSIM, too.
Another odd thing I've noticed is that the choice to select the carrier in iOS is greyed out and inoperable for the Xfinity Mobile SIM, while it will still work with T-Mobile and AT&T. I don't even know why somebody would want to do that, but you can't do it with Xfinity.
A good plus for Xfinity Mobile is that their iOS application allows you to keep track of your data usage, and the application will have an inescapable warning for you if you should really be on the 45.00/unlimited plan instead of 12.00/gig. You can switch to 45.00/unlimited in the middle of a billing period and get the full advantage of 45.00 v 12.00.
I am defaulted to 12.00/gig and I've set LTE to be for data only. That way if I have to make or receive a call while on cellular, I will not be using data.
Remember, too, that iMessages use data. If you're trying to stay on 12.00/gig, you'll want to use short SMS messages to avoid data.
I'm still learning their system, but I think they're definitely worth it for having a slightly different coverage area that might be of benefit to you here and there.

Xfinity is a mnvo of Verizon you will not get roaming and only use Verizon native network witch is pretty still good coverage.
Just a warning that as a Verizon MVNO, Xfinity Mobile will be de-prioritized in peak periods. This is something I've tested, personally, and during peak periods there is a huge difference in data throughput if I am using my Xfinity Mobile data and comparing a speed test with someone whose primary cellular is Verizon.
