@NickvNetworking @domi007 Thanks Nick Comprion's test eUICC works ok though it's v2.1 of the TCA spec. Also prior to v3 of the SGP.22 spec the scp03t info was a bit scattered around other specs, but v3 BSP is better. I used SGP.26 v1.2 certs which match what Comprion have used https://t.co/LEHaaS3W9G

@domi007 @sysmocom @LaF0rge Looking at https://t.co/tYGH7ca1gL section 9 does appear to state that an applet can implement SUCICalculator to then become the default SUCI calculator. Though only one per SIM profile so a preinstalled one would poerhaps take precedence

[Chris @mode51software]

@domi007 @sysmocom @LaF0rge Fair point it's probably better to make it something that is burned in. If milenage could be provided in a similar way that may be counter-productive! For more sophisticated eUICC OS platforms in the future add on algos could be useful, though perhaps as OS updates

[Chris @mode51software]

@sysmocom @domi007 @LaF0rge Is the SUCI calc by USIM on the roadmap? It would be nice if GET IDENTITY could call a 3rd party (open source, auditable) SIM applet that implemented the SUCI but perhaps the Javacard API env is a bit too limited at this point

Multi USIM looks like a gem in Rel 17. In Dual SIM the primary connection is usually 4G and the secondary 2G/3G. Multi USIM will enable multiple SIMs to share the primary 5G stack side by side across multiple networks. Signalling looks problematic though! https://t.co/UBPAHVlyL6
