Hi other users,
I'm still confused about the changes in the HPPLMN search, which was introduced with mfw 1.3.2, when global SIMs are used (IMSI starting with '9', e.g. "90140" Deutsche Telekom, 1NCE ).
According Nordic (see hpplmn search - difference mfw 1.3.1 and 1.3.2):
"The fix in 1.3.2 was that PLMN starting with 9 is a global PLMN and can be found from anywhere and that is why it is also considered as suitable candidate in HPPLMN search."
In my experience the "90140" can not be found at all. The statement "can be found from anywhere" seems to be wrong, it's in my experience "nowhere".
Unfortunately, the 3GPP specs are no that easy to read, and so I didn't found the statements related to the usage of global SIMs.
Anyway, sorry to write that, I consider that Nordic's expertise about such global SIMs is wrong. There are no networks, which reports the global PLMN ("9xxxx"), but instead, such global SIMs are used for quite a lot of common networks for roaming, e.g. Roaming mobile IoT networks for the "90140".
My devices with global SIMs (IMSI "90140") frequently reports "26201" listed by the Telekom at the very top. That is also the top of the operator's PLMN selector on the SIM card. But my device never ever connects to a network reporting "90140".
Therefore:
I would really appreciate, if other users of global SIMs comment here, if their devices are really able to find such network with a "9xxxx" PLMN or not.
