I don't know what devil you are representing? The assertion is that you can buy a new 4G phone today and get booted off their network for using it because it is not on a list of phone models they sold.

It's not an entirely accurate statement.

I can also buy a brand "new" telegraph today from Amazon for $10. Should carriers still support something that was created 100 years ago?

You can buy a phone with the latest technology in it, designed and built to tomorrow's specification; and AT&T still won't support it, unless the manufacturer has paid them to certify it and put it on this list[0].

Very few people are advocating that they keep 3G around using 5x5MHz of spectrum for little gain; people are just advocating that they not limit consumers from using the supported device of their choice regardless of whether it's on the list.

>Should carriers still support something that was created 100 years ago?

No one is saying ATT should continue operating their 3G network. On what grounds are they terminating subscriptions?

Also, there's more than just Apple/Samsung/Google. Operators are shutting off 3G, but keeping 2G alive for a while longer for crap that's abundant, and doesn't need anything more anyway.

Leaving a small sliver of 2G service would have avoided obsoleting a lot of devices. Support emergency calls, very low data rate applications, and play an announcement if someone tries to make a call "we're sorry, your phone sucks, or we're too lazy to let it provision a VoLTE profile, so buy something new if you want to talk"

My home alarm company made all kinds of complaints because they had to upgrade the modem in my home alarm notification service to be 4G.
