@micahflee lemme guess: @eff just took a multi-network eSIM and multi-network WWAN modules to scan for "#deauth" / "#EvilTwin" attacks?
Cuz I remember @heiseonline or @golem actually suggest this as a method to detect #IMSIcatchers without requiring an expensive #SDR:
AFAIK #GSMK uses that same technique for their #Baseband-#Firewall to automatically detect #Interception attempts and deploy countermeasures!

Won't be able to find anything about the visiting carrier though sadly. They can't create tickets for their engineers without me having a contract with them, and the first line only has very basic information. Can't even register on their community portal for the same reason :/
Alright, progress. My home carrier finally explicitly confirmed that they don't have #VoLTE Roaming, so the problem isn't on my side. Sadly no schedule/plans to have it implemented. Best case I only stop receiving calls (honestly for the better perhaps, with all the spam calls, hah), but SMS may still keep working if the visiting carrier supports SMS over #LTE signalling. Worst case I won't be able to use it at all, but we'll see.
Not that it would fix anything, but my #iPhone is also picking an incorrect carrier bundle for the roaming SIM card. There's no way to override it apparently. And the reason seems to be that on this particular phone this SIM never connected to its home network, it was always roaming.
No, they won’t! How would #VoLTE magically work without an IMS configuration, and if nobody claims VoLTE roaming support, especially for the carrier in question.
Once again very hard/impossible to reach the tech-capable people who actually know what they're talking about, rather than first-level support that only knows how to read from a script.
I’m having another episode of high frustration with dumb "tech" support. This time it's about #VoLTE support in roaming.
I just realised the other day that my foreign SIM card will stop accepting calls and SMS messages once #Sweden shuts down the #3G networks in December this year. Had strong doubts about VoLTE working in roaming, and confirmed today that it indeed didn’t, and the phone fell back to 3G.
Home carrier points at the visiting carrier, and the latter says things will keep working.
"[...] to provide privacy protection, networks on both ends of the roaming interface must implement the SEPP function. Getting all roaming partners to implement SEPP may be extremely challenging; of the 351 network operators reported to have launched 5G services, only 41 have launched 5G cloud-native architectures according to the Global Mobile Suppliers Association (GSA) as of April 2023. The remaining 310 operators are still using the Non-standalone Architecture (NSA) for 5G, which lets mobile operators bypass the SEPP feature in 5G roaming while still providing the improved speed and reduced latency benefits of the 5G radio access network.
According to interviews with telecommunications security vendors at the Mobile World Congress (MWC) conference in March 2023, only a handful of operators have deployed SEPP, let alone are actually using it. The effect is that many operators are not integrating the security and privacy benefits of the 5G standards when they are deploying 5G networks."

#BigBadger1 wondered why this isnt promoted more. Granted, these days people change their phone almost as often as their socks, so possibly not a problem

뉴스 다이제스트 : 다가오는 3G 서비스 종료
이제 1% 미만…3G 조기 종료 초읽기◎애플, '완성형 시리' 출시 연기 발표..."올해에서 내년으로 늦춰"◎'국민 메신저' 카카오톡은 한국만 쓴다?
#Tele2 and #Telenor (as part of #Net4Mobility) in Sweden announced that they will be shutting down #2G and #3G mobile networks on December 1st, 2025. Tre (Three) is expected to be done by end of year as well. At that point 3G will be fully gone, and only #Telia will keep their 2G network until end of 2027.
Closure of 3G mobile network providing coverage issues outside main centres, at a time many places are keeping the networks active for emergencies.
The 3G shutdown was expected to mostly impact people in remote areas who had been getting what was described by Telstra and Optus as "fortuitous" coverage.
Fortuitous coverage refers to people who were not on the official 3G map, but received a signal anyway.
Many were likely to also struggle to get a 4G signal because it doesn't travel as far as 3G.
Mr Taylor said the patchy coverage had caused problems during harvest.
He had to drive around to find reception to keep in touch with truck drivers and grain buyers.

Just had to negotiate the world of 4G for my father in law who had a Doro 2G/3G handset and refuses touchscreens (even SMS texting is not a thing for him). His mobile provider is switching off #3G and he wasn’t sure what to do. We went with a Nokia 105 with #4G for £25 which should see him through past 2033, but it’s getting to be a squeeze. A bit like trying to find a Betamax recorder that will output to HDMI. I suspect dumb phones for #5G won’t even be a thing.
But yeah, even back when #3G was a thing you'd barely get a few minutes at affordable rates without getting throttled, and sadly the pay-as-you-go plans that bill per time and not traffic have all gone.
Samsung bendruomenėje glaustai pasidalinau kodėl reikėtų vengti 2G mobiliojo ryšio protokolų ir standartų grupės 
Visa bėda su 2G yra tame, kad standartuose numatyta prievolė abonentui (mobiliajam telefonui su SIM kortele) autentifikuotis (prisistatyti save identifikuojant ir taip gauti prieigą), tačiau nėra numatyta, kad tinklas turi įrodyti savo tapatybę abonentui - abonentas iš esmės negali žinoti ar prisijungė prie „tikro“ tinklo, ar piktavalių klastotės.
3G standartų ir protokolų grupėje jau numatyta, kad tiek abonentas, tiek ir tinklas turi prisistatyti vienas kitam. Būtent dėl šių priežasčių mums tenka karts nuo karto pasikeisti SIM korteles, kai operatorius reikalauja tai padaryti - būtent SIM kortelės savyje talpina identifikatorius ir sertifikatus tokiam abipusiam tapatybės patvirtinimui. Kiekviena vėlesnė karta - 4G, 5G ir t.t. turi vis stipresnes priemones užtikrinti susijungimo ir po to keliaujančių duomenų srauto tarp mūsų įrenginio ir tinklo saugumą.
Labai apibendrinant, mobiliojo ryšio abonento tapatybės gaudyklės (International Mobile Subscriber Identity catcher - IMSI-catcher), praktijoje vadinami stingray arba tiesiog kenkėjiškos mobiliojo ryšio stotys, veikia tokiu principu, kad bando sutrikdyti ar užgožti prieigą prie 3G ir aukštesnių grupių standartų, kad įrenginys mažintų reiklumą (downgrade) protokolams ir standartams, siekdamas užmegzti bent kokį nors įmanomą ryšį. Piktavalių pirminis uždavinys - daryti viską iki įrenginys sutiks komunikuoti prastai apsaugotais (lengvai šiuolaikinėmis priemonėmis iššifruojamais) ar visai neapsaugotais ryšio protokolais 
I have a theory that I want to share about sites that aren't part of the #Cornerstone agreement for some reason and are #O2 only.
I reckon the LACs indicate when a site is O2 host and isn't shared with another network. I think whenever a 2G LAC begins with 22xxx, it's O2 only (regular sites begin with a 21xxx LAC).
* Case 1: Eastern Avenue in Mitcheldean. Broadcasts under BTS 9147 on LAC 22212, using an O2 host site ID of 038910.
* Case 2: random airport in Wales. Broadcasts on 2G, 3G and 4G, no indication of the 4G eNB popping up on Vodafone. Broadcasts on 2G under BTS 4147 with LAC 22860, site ID is 051035. 4G eNB is 545714 afaik (I couldn't be bothered to convert the cell ID to hexadecimal to check).
I think something similar happens on some O2 only 3G only sites, but I can't really confirm whether it's on any macro sites. I can confirm it happens on some boostboxes though, with 18xxx and 19xxx LACs.
