Hello,
I'm testing nrf9160 with 2 SIM-Cards in Austria.
I'm always using automatic connect mode and only NB-IoT.
On Both SIM Cards HPPLMN Scan is enabled:
6F31 - EF_HPPLMN - (Higher Priority PLMN search period)
> AT+CRSM=176,28465,0,0,1
+CRSM: 144,0,"01"
SIM 1 - Global SIM from Deutsche Telekom
IMSI: 9014057100XXXXX
EHPLMN: 901-40 (Global SIM)
OPLMN:
262-01
232-03
214-07
222-01
208-01
204-16
228-01
286-01
234-30
310-260
SIM 1 automatically connects to 232-03 (Magenta Austria) at my location.
After ~2 Minutes and then every 2 Hours die UE starts an HPPLMN scan.
SIM 2 - Telefonica SIM
IMSI: 2620756000XXXXX
EHPLMN:
262-07,
262-03
OPLMN: 262-07
SIM 2 automatically connects to 232-05 (Drei Hutchison Austria) at my location.
With this SIM 2 the UE never starts an HHPLMN Scan.
My Questions are:
-
Why does the UE start an HPPLMN scan with SIM 1 even though it is connected to 232-03, which is also in the OPLMN list and the only one for 232?
-
Why doesn't the UE start any HPPLMN scans with SIM 2?
Thank you!

Manuel
