From a factory reset it is just impossible to create a different profilae as any change apply to other profile. Really big issue , as Profiling doesn't work anymore !!!
I think you cannot anymore get a SIM switch by applying a profile with different default SIL setting as since FW.07 it is not possible anymore to get different configuration in profile, including default SIM setting
Formerly , I didn't notice profiling was no more effective and before I applied a factory reset (because of this FW .07 other issue), I tried to switch to a profile formerly created on the previous FW version, and I was able to see different default SIM on legacy profile but no SIM switch occured when I changed for this old profile.
I guess to reproduce, you need to create on the previous FW some profile with different default SIM. Then upgrade to FW .07 and switch to a profile (created with previous FW) which uses a different default SIM.
Honnestly I think this is linked with the general profile issue with FW .07.
