I’m using MC8790 firmware
K2_0_7_35AP C:/WS/FW/K2_0_7_35AP/MSM6290/SRC 2010/03/04 17:37:08
and in some modems I can’t change the band into OD 850 (as shown )
and if I take the same sim card ans use another modem (same firmware ) I can change it
is there any reason of that?
Are you buying those MC8790V at same order?
To me, some modules maybe coming from different order/shipment in which configured for specific carrier or country so band 850 was not listed.
Please check AT!CUSTOM? and AT!PRIID? and confirm with your distributor.
in this one I don’t have the option of band 850
PRI Part Number: 9992974
and in this one I have the option of band 850
PRI Part Number: 9992763
The AT response confirmed these two modules are from different SKU, 9992763 vs 9992974, and various features configured is different (as per !CUSTOM).
In this case, the PRLREGION option caused band 850 hidden.
Please conslidate with your distributor and see if they can re-arrange the right modules to you.
I’ll see what I can do
Thank for the help and the explaining .
pleae how to change the sku with command AT!PRIID ,thanks
