Well it appears there is a drop-dead date for discontinuing (copper) landline service in IL of 3/15/27:

There was a segment of this specifically discussing IL, in a segment on the Today show a couple weeks ago:
A client/friend of mine got this very letter first week of December, after just getting the “grandfathering” letter in September. Thing is, she gets a “concession” phone line for only $9/month, as she is an Ameritech/SBC retiree. But in doing some research for her, it appears her options are pretty limited at keeping this:
-If she does the “wireless replacement”, they may/may not honor the same rate for the service. Also, she is not thrilled with having to rely on a cell tower, for an emergency situation & I have grave doubts that the service, in fact, sends an actual home address to E911, like all landlines in Springfield do now. This IS important to her, as she is elderly & lives alone.
-While she does have AT&T fiber (internet) available, again if they would honor the rate for the home phone portion, she would be responsible for paying for a (minimal) fiber internet service - at least according to info from AT&T. The problem is, she does NOT want to dump Comcast TV service, as she is happy with the TV lineup & gets FREE Peacock for life, as part of Xfinity rewards; she also has internet thru them, as it brings down the cost of her base TV service. She absolutely does NOT want to go to a streaming replacement service!
Honestly at this point, I told her her best option might be to just forget the concession, & switch the landline to Comcast. While it’s more expensive than what she’s currently paying, it’s much cheaper than having to (double) pay for AT&T internet, & it WILL send E911 addressing to our PSAP. Since it’s a managed service, if something happens to the landline, Comcast is responsible for getting it back up, without her trying to troubleshoot if I was unavailable. She is probably going to do it in the next couple months, after I’m back from vacation.
