That’s good news, @urszula!

I am switching my carrier here in the USA in a few days from an AT&T-network-based MVNO (Pure TalkUSA) to a T-Mobile-network-based MVNO (Mint Mobile), which supports Voice over LTE (VoLTE).

T-Mobile USA (TMUS) bought Sprint, which owned Boost Mobile.

DISH Network, a satellite-TV provider, now operates Boost Mobile in the USA, which uses the TMUS network. (Per Wikipedia, " In Australia, it [the Boost Mobile brand] is operated by Boost Tel PTY Limited using Telstra’s mobile network.")

The aforementioned Fierce Wireless article makes an intriguing point about a possible conflict between DISH and T-Mobile:

…asked about T-Mobile shutting off [by 1 January 2022] the old Sprint 3G CDMA network. T-Mobile, according to Dish, is conveniently waiting in the wings to grab Boost Mobile customers as its own when their CDMA handsets no longer work.

So, it should be interesting to see how Boost Mobile (the U.S. version) works internationally with the Mudita Pure.

AT&T plans to shutter its 3G network by 22 February 2022, per this:

“When the 2G network was sunset, service providers announced a 4-year transition period. At the time, the alarm industry operated approximately 2.4 million cellular-based radios,” the group told the FCC in a filing earlier this month. With 3G, though, the industry is struggling to deal with even more devices in an even shorter timeframe.

Specifically, the group said around 2.4 million alarms connect to Verizon’s 3G network, while 3.6 million connect to AT&T’s 3G network. After several delays, Verizon has announced a 3G sunset of December 31, 2022, “which the alarm industry is fighting to meet,” according to AICC. But AT&T plans to shutter its own 3G network even earlier, by February 22, 2022.
