Dual SIM supported by most except Xfinity

While eSIM technology has been around since 2016-2017 and dual SIMs have existed even longer in mobile phones, why is it that Xfinity is one of the only carriers that does not allow 2 lines on 1 phone?

It's easy to say, "dual SIMs are not supported", but they actually are.  Why won't Xfinity allow something so useful?  Why are many other carriers supporting this but not Xfinity?

Xfinity, please fix this because it's not an issue and it just makes you look archaic.

@user_acrzz7 You should check this support document for some clarification on the rule; https://www.xfinity.com/support/articles/what-are-sims-how-do-they-work

At this time, Xfinity only supports one mobile service (Xfinity Mobile, Comcast Business Mobile, or NOW Mobile) per device, even if you have a dual SIM device. However, dual SIM functionality can support adding a second line from another domestic service provider or a local data plan if you’re traveling outside of the country.

Note: Your phone must be unlocked to use its dual SIM functionality with another service provider.
