T-Mobile Will Soon Begin Lte Phase-Out

Agreed. These technologies are the backbone of a lot (most?) of IoT devices, so unlike the article's description of "devices" in terms of "consumer handheld phones (that are often replaced every 3 years)", the impact here would be much deeper. And these technologies have been and are continuing to be sold as stable. For example, see https://www.nordicsemi.com/Products/Wireless/Low-power-cellu... . Quote: "Future-proof: LTE-M and NB-IoT are slated for support beyond 2040, ensuring devices' long lifespans. Subscriptions guarantee a reliable network, in contrast to other LPWANs that could shut down preemptively, risking your business." On the other hand, I guess I haven't seen as many IoT devices choose T-Mobile as a carrier either, so maybe it's just that T-Mobile knows their market.
