Can't enter Data State

Legacy Legacy AirPrime modules

Hi,

I’m trying to activate an IP PDP context on my SL6087 in order to send data using AT commands. Here is the AT sequence I’ve used:

at+cgatt=1
OK
at+cgdcont=1,“IP”,“movistar.pe”
OK
at+cgact=1,1
OK
at+cgdata=1
+CME ERROR: 3

As you can see everything is OK except when I type +CGDATA. Apart from that, I’ve tried to connect to a GSM network operator but I can’t, so I don’t know if these two issues are related. I get the following:

at+cops=?
+COPS: (0,“movistar”,“movistar”,“71606”) // The ‘0’ parameter means (acoording to the Interface Guide) unknown network. I don’t know how to fix this either.

Any ideas will be welcome.
Thanks

I’ve realized that an APN has an ID user and a password but I haven’t made use of this data. Does anyone know the AT command to enter this data?

Thanks in advance

if you use SL6087 to transfer data by tcp/ip ,advice to use wipsoft.
