First you can use the generic AT commands to check if getting a successful IP address after activating the PDP profile.
AT+CREG? +CREG: 0,5 OK Device is registered and is roaming. Checking if device is already connected... AT+CGACT? +CGACT: 1,0 +CGACT: 2,0 +CGACT: 3,0 OK AT+CMEE=1 OK Attaching to network... AT+CGATT=1 OK Connecting... AT+CGACT=1, 1 OK Connection is successful AT+CGACT? +CGACT: 1,1 +CGACT: 2,0 +CGACT: 3,0 OK Device is connected. AT+CGPADDR= 1 +CGPADDR: 1,"10.102.162.113" OK IP Address of the connected profile is "10.102.162.113" In your example, you can check the service state of the service profile 0. If the connection is successful, you should see that IP address has been assigned to service profile 0. At^SISO? ^SISO:0,"Transparent","4","2","0","16","10.10.0.200:1024","10.10.0.108:65532" OKOn the AT Command Tester tool, in the ‘Data Call’ tab, you can add a PDP profile which will store the APN information. First do a ‘Get PDP Comtexts’ to read the PDP profiles stored in the device. Then you can either edit an existing one or add a new profile.
//AT Command to add a PDP profile AT+CGDCONT= 2,"IP","internet.vodafone.net","0.0.0.0",0,0 OK PDP Context list updated sucessfully AT+CGDCONT? +CGDCONT: 1,"IP","bluevia.movistar.es","0.0.0.0",0,0 +CGDCONT: 2,"IP","internet.vodafone.net","0.0.0.0",0,0 +CGDCONT: 3,"IP","","0.0.0.0",0,0 OK Following connection profiles are available, CID-> 1 PDP Type->IP APN->bluevia.movistar.es PDP Address->0.0.0.0 Data Compression->0 Header Compression->0 CID-> 2 PDP Type->IP APN->internet.vodafone.net PDP Address->0.0.0.0 Data Compression->0 Header Compression->0 CID-> 3 PDP Type->IP APN-> PDP Address->0.0.0.0 Data Compression->0 Header Compression->0 Checking registration status...

But you should this should return successful AT+CGACT=1, 2 +CME ERROR: 133 Connect Failure - 133Hi,
CME Error 133 – “requested service option not subscribed“. This means that the SIM is not provisioned for the service you’re requesting..
What you can do,
– You can confirm with your network operator whether your SIM has been activated for data service
– Try another SIM card that you think is activeYou can use the AT^SISO? command to query the status of the service
Here is the response format. .^SISO: <srvprofileid>, <srvparmtag>value "srvType" [, <srvstate>, <socketstate>, <rxcount>, <txcount>, <locaddr>, <remaddr>] [^SISO: ...] OKAt^SISO? ^SISO:0,"Transparent","4","2","0","16","10.10.0.200:1024","10.10.0.108:65532" OK- This reply was modified 6 years, 12 months ago by Admin.
What response are you getting for AT^SISO? If the connection to the remote server is not successful, you would not have IP assignment in the AT^SISO response.
What is the response for AT+CGACT?
You could then check if any of the profile if active and query the IP address as shown below. This only validates that APN is correct. IP assignments for remote server in the AT^SISO validates remote server connection.
AT+CGACT? +CGACT: 1,1 +CGACT: 2,0 +CGACT: 3,0 OK Device is connected. AT+CGPADDR= 1 +CGPADDR: 1,"10.102.162.113" OKHi Burak,
Based on your logs, it looks like device is successfully connected to the network. What is our question?
