“I don’t know. What are issues or problems about this? “

The issue is that I bought a new used unlocked (ATT) GSM Samsung Xcover Field Pro phone (can't justify new ones) and it fails to work (Emergency calls only) when I put my 20 year old TM sim in it. It fails ONLY because it lacks

-- Extended LTE

-- VoLTE

Which my present phone ALSO lacks -- but still works on the TM network (it's grandfathered). So, it shows that TM blocks BYO phones (not originally TM phones) ONLY because of this "OPTIONAL" requirement that does not diminish their network in any way.

So, I wasted my money on unlocked GSM standard phone that should work on the TM network -- but doesn't only because of likely greed to sell more TM supplied phones -- having TM features that many don't need and don't want to pay for. I just want a pretty basic smart phone.

Gracias,

so which feature is it that many dont need or want? the ability to make data calls for improved call quality?  since 3G is gone..and 2G is next..that only leaves data calls..
