Engadget: T-Mobile is under fire again over its 2021 data breach. “T-Mobile is once again being sued by Washington state over the 2021 data breach which exposed sensitive information for over 79 million people, The Verge reports. The lawsuit filed on Monday alleges that T-Mobile had been aware of various security loopholes in its systems for years but didn’t take any action.”

Through Hurricanes Helene and Milton, Amateur Radio Triumphs When All Else Fails

While some residents in hurricane-impacted areas can’t send texts or make calls, #AmateurRadio enthusiasts are helping communicate requests for help and messages between loved ones.

"Hurricanes have wreaked havoc on the United States over the past month. More than 200 people have been confirmed dead as a result of #HurricaneHelene and many more have gone missing, making it the most destructive US hurricane since Katrina in 2005. Nearly a week after Helene made landfall, #CellService #DeadZones plagued the Carolinas, leaving thousands of residents unable to reach their friends, families, and even emergency responders. As #HurricaneMilton builds in the Gulf of Mexico this week, radio operators in #Florida are also preparing to launch their net—a group of operators communicating live over the air. Scott Roberts, an amateur radio section manager for northern Florida, said that operators in his area started checking their equipment and making plans to deploy to shelters as of Monday.

"There are more than 1 million licensed radio amateurs in the US like Witherspoon and Roberts, according to a Federal Communications Commission spokesperson who spoke to WIRED last week. Some amateur radio bands are short bands, reaching only small communities of people, while others cover hundreds and even thousands of miles. When #CommunicationInfrastructure fails, like #CellularNetworks during a natural disaster, the FCC allows for amateur radio operators to assist in recovery efforts.

"Gordon Mooneyhan, spokesperson for the American Radio Relay League, said he knows of three main #repeaters being used to convey messages inside the disaster area from Hurricane Helene, including the #MountMitchellRepeater, which is located at the highest point in #NorthCarolina at 6,600 feet and boosts localized radio broadcasts to a wider network. This is where Witherspoon read off supply requests and #RoadClosures."

A #PSA for anyone living, staying, entering or even travelling to/from #Australia:

Apparently, #Australia decided to mandate it's #GSM systems to be shutdown because some #GalaxyBrainChair wanted to yeet #2G & #3G and demand everything to use #4G & #5G when in fact #VoLTE support is spotty at best and #EmergencyCalling oftentimes is explicitly hardcoded to not use #WIFIcalling or VoLTE as providing #triangulation and #LocationData via #SS7 is a desired feature when someone calls EMS, Fire Dept or the Police for help...

  • So essentially #tourists and anyone who hasn't an explicitly fully VoLTE-functional device they tested and verified to also do #EmergencyCalls via VoLTE are fecked with no reception when they need it the most!

  • This WILL KILL PEOPLE!!!

As much as we want to bitch about #GSM & #GPRS / #UMTS being #outdated and #inefficient, there are reasons to at least keep 2G available - ranging from lower power consumption to higher resilience in emergency situations.

  • #NewZealand for example does shutdown non-#EmergencyCalls during severe #Earthquakes so that people trapped and/or in need of urgent assistance can get through to dispatch operators and everyone else has to get in line and take a number aka. use #SMS or if existing #Internet to say "I'm fine!"...

  • If the Ozzies really need that juicy #UHF #SubGHz #Spectrum it's totally feasible to instead change the #allocations and reconfigure #CellularNetworks to use lesser bandwith for 2G (i.e. only keeping the absolute mininum of channels available for any service) and thus clear up space...

And to add insult to injury, Australia passed a #NorthKorea|n-alike #CellPhone #ImportBan for any device that doesn't do i.e. the bespoke proprietary garbage that i.e. #Telstra, #Vodafone and #Optus do with the #baseband modems of their #branded devices...

Seriously, which #TechIlliterate dickhead decided it's a good idea to do that #3Gshutdown in Australia without even a basic 2G network up and running at all?
