I tried to get the length of EF_MSISDN :
as written in guide section 3.3 (Telit_Modules_Software_User_Guide_r1), the 15th byte is 01 so I don’t think is the right length.
So I supposed that my length was 26 as in the example so I entered :
I don’t know the meaning of this answer. (X represents my international phone number)
I check Phonenum :
What should I do ?
the Telit Modules Software User Guide (latest is r12) is not applicable to UC864.
You have to refer to UC864-E/G/WD/WDU Software User Guide.
The procedure is easier since you can used the "ON" phonebook.
“ON” – SIM (or MT) own numbers (MSI torage may be available through +CNUM also).
Hereby, what I get :
at+cpbw=1,"1XXXXXXXXXX",145+CME ERROR: unknown
I tried non-international format too and same result.
+CME ERROR: unknown
Maybe the double quotes will make a change?
I tried with double quotes and I get same result.
I even tried the example, same result.
When I start my UC864-G, I first :
AT+CMEE = 2
I tried with a quite old firmware version and is working as Andrea wrote.
What is your module firmware versio, AT+CGMR?
I’m following for Guy.
I get :
this is strange.
Did you try to store the MSISDN on that specific SIM using anothe phone/module and check if it is then readable with AT+CNUM ?
We can investigate further providing a trace tool but I what to be sure that this SIM allows to store MSISDN value inside.
