@quasigod there's a reason #SimLock and #NetLock died in #Europe over a decade ago.
That being said even #Prepaid providers don't lock their devices anymore but instead they just sell people devices at cost with a tiny margin and make their €€€ longterm bunding a free #SIM with every purchase.
Let’s give this a shot.
I’m an experienced backend software dev, with significant experience in #telco, #database, security and pharma industries. I do everything from setting up teams to writing code to architecting infrastructure, networks, cloud, setting up CI and Makefiles.
The languages I have most experience with in recent years are #rustlang, #python and #golang.
I typically work as a contractor, but I’m happy to look at other setups as well. I’m based in Denmark.

And this, my friends, is why you disclose breaches, tell people about the involved systems/software, and be open about its impact.
Because while this dumpsterfire continues, all other telcos have no clue about whether they are compromised too.
Unless we assume all other telcos have received a TLP:RED notification with all TTPs, IOCs, including YARA, SNORT en Sigma sets.
From personal experience: a snowball’s chance in hell.
T-Mobile is one of the victims of the massive Chinese breach of telecom firms

You want to have anonymous prepaid SIM cards because you want to prank people.
I want anonymous prepaid SIM cards because KYC is the illicit activity on something where fraud at the expense of the telco is impossible and because it's cyberfacist bs!
And in #Germany it took a Natural Disaster with a triple digit bodycount for #CellBroadcast to be reactivated per legal mandate and #2G to remain online...
The fact that Telstra was unable to say how many devices roamed their Network should be seen as criminal incompetence cuz asking something like: "How many foreign devices are #roaming in your network?" is a standard #FAQ I'd expect them to put into their public financial reports - even as a #footnote re: #revenue [i.e. total devices, total revenue, average Calls / SMS / data per roaming device] cuz that's standard #metrics every #Telco & #ISP does create anyway...
I just finished watching an absolutely insane video on mobile phone security, and I really encourage you to watch it in full as well:
I was aware of some of these issues with SS7, but that they are readily available to a YouTuber? Who can demonstrate it in the real-world, hacking another YouTuber in a different country? With an attack that is realistically only in the 4-5 figure range to perform? 
I remember seeing public IPv4 addresses from Xerox and the US DoD assigned to DTAG LTE SIMs internally in Germany (04/2020), probably because they ran out of RFC1918 space. Do you have other such examples? I would like to collect them. (boosts in the IP/ net admin bubble appreciated!)
It's been a while and I think a refresh #introduction is OK:
By day, I'm a principal doing #5G and #analytics at #Microsoft after too much time in the #telco industry watching people reinvent the wheels that run the internet.
By night, I'm an undercover #hardware and #Apple guy messing with with #electronics, #3dprinting and #synthesizers.
I like my programming languages sans hype and remember when 8-bit microcomputers ruled the Earth, singing ANSI colored songs to each other via phone lines.
Some new Telco utils 
are now installed in our x86_64, arm64 and partially on RISCV64 images
