@bob_zim @micahflee @heiseonline @golem Makes sense.

  • After all, the whole #IMSIcatcher system can be detected by passive #SIGINT as it's an active attack on mobile networks.

I wounder if I can get a compatible device in #Germany as well...

  • Bonis points if that device has a freely reprogrammable #IMEI to allow hiding it's identity.

@phlogiston @torproject @guardianproject at least @BNetzA & @Bundesregierung didn't cancel #2G / #GSM / #EDGE with the #3Gshutdown like #Australia did recently.

And don't even get me started on #VoLTE [support](https://www.youtube.com/watch?v=Q6qb9dml6So)... - Like #Australia had *the glorious idea* of shutting down #3G *AND* #2G as well as *#allowlisting* [only specific](https://www.youtube.com/watch?v=RPlTz-3estM) #IMEI|s, [banning > 500k devices](https://www.youtube.com/watch?v=zIJavqEzEIw) for no good reason. Also *most* #VoLTE / #Vo5G - devices *explicitly use #2G / #3G for #EmergencyCalls! - Which is *#funfuckingtastic* in a place like Australia where *basically everything in nature conspires to hurt or kill humans*! #DownUnder #AUSpol #AUpol #tech #2Gshutdown #3Gshutdown #EmergencyCalling

1) #CloudAct is just #CyberFacism, look it up!
https://en.wikipedia.org/wiki/CLOUD_Act

-

2) @signalapp 's #Server code is proprietary and since it's centralized we can't trust that the code they release is what's running on their backend!

-

3) #Signal still demands #PhoneNumbers which are #PII either by association (#Number => #ICCID = #SIM = #IMSI => #IMEI => Location Data as I explained beforetwice) or mandatory #KYC / #ID requirements (even on prepaid cards), which an increasing amount of juristictions do...

But don't take my word for it.

@lucasmz @Avitus @david_chisnall the benefit of #XMPP+#OMEMO is that there are several providers, including free options...

All #PII incl. #PhoneNumbers can and will be abused by existing governments and if users don't pay, then they are the product and their data is the one to be sold.

After all, you have the same cost problem with phone numbers. Even if one doesn't pay per line/number and never pay for calls and texts, they still have to top it up to extent validity.

  • And again: It's way easier for a government to demand an ID for a #SIM that works in networks around their country (i.e. #Turkey demands registration on a per-#IMEI - basis *with #ID) than to tunnel XMPP+OMEMO through @torproject over #EDGEland-speed #2G networks.

Plus you relying an unfixably insecure #Telephony makes a system inherently unsafer than it needs to be...

  • This is how people get caught!

Also #Signal is able and willing to use said PII to restrict and ban users and if I were some dissident in Cuba or North Korea or even just Eritrea or Yemen I'd not rely on non-enforcement of #OFAC / #USML / #ITAR since Signal can obviously distinguish & identify accounts by virgue if their #PhoneNumber!

  • Always think "How can this be weaponized against someone?" when it comes to #privacy!

And don't even get me started on #VoLTE support...

Also most #VoLTE / #Vo5G - devices *explicitly use #2G / #3G for #EmergencyCalls!

  • Which is #funfuckingtastic in a place like Australia where basically everything in nature conspires to hurt or kill humans!

[#TLDR: JUST TELL ME IF YOUR TABLET CAN DO #CALLS!]

#DearVendors of #Android-#Tablets:

Off all the #Functions you can put into a #Specifications Sheet of your Devices there's one you should ALWAYS answer clearly on your #Website:

DOES YOUR TABLET [with #4G / #5G / …) SUPPORT MAKING PHONE CALLS?

Like: IS IT TOO MUCH TO ASK TO HAVE THAT INFO IN THE SPECSHEETS?

You're obviously able to list all the #Codecs natively supported and the user-available storage as well as supported Frequency Bands, WWAN modes, WiFi channel width and the Display Glass vs. Panel dimensions including DPI of the latter and whether or not it has a hall effect sensor to detect your overpriced 1st party tablet covers!

Now some folks may ask: "WHY does this matter?" or outright dismiss this as a problem.

Listen:
Not everyone is able or willing to carry two devices when 1 SHOULD BE ENOUGH and also some places (i.e. #Turkey) have #ImportRestrictions re: #MobileDevices, so having more than 1 #IMEI is already a "NOPE!" by the authorities.

  • Also this isn't something one can "fix" post-purchase like installing #VLC to decode some obscure file format in Software: Either the #Baseband and #ROM support #PhoneCalls or they don't!

So why do NONE of the #Tablet manufacturers allow to #search or #filter for that???

NO, instead one has to download an obscenely huge #PDF just to then read on page 34 that for any "#telephony" function you NEED YET ANOTHER DEVICE FROM THE SAME MANUFACTURER AND HAVE TO SIGNUP WITH AN ACCOUNT and even that level of #abuse WON'T GUARANTEE THAT IT WORKS...

  • I mean, come on, this ain't some obscure functionality like #OMAPI to do some "evil sourcery" like managing an #eSIM that is in a #SIM-Card form factor!

Pretty shure A LOT of other folks have the same question and ain't willing to get yet another device & #SIM just to recieve the occasional call because #TechIlliterates can't be assed to send an #eMail or learn #XMPP+#OMEMO to message one...

  • Obviously they same manufacturers are able and willing to specify f-stops of the built-in cameras and list EVERY SINGLE #WEARABLE they made and certify as 'compatible' with, as if anyone is gonna take their non-#waterproof #Tablet for a marathon or god forbid triathlon...
