===Step 1: Accessing the AT Port===

1. Identify the AT Port for the modem; in this example, it’s COM6.<br>
2. Open Putty on your computer to access the AT command interface.<br>
3. In Putty add the following information as shown below:<br>

===Step 2: Check and Unlock the SIM Card===

1. In the Putty window, send the following AT command to check SIM status:<br>
 AT+CPIN?
* If the response shows: '''+CPIN: SIM PIN''', the SIM card is locked.<br>
2. To unlock the SIM, send the command with the PIN code (replace 0000 with the actual PIN)<br>
 AT+CPIN=0000
3. Verify that the SIM is unlocked by running the command again:<br>
 AT+CPIN?
* The response should display''' +CPIN: READY'''.

===Step 3: Check and Configure APN===

1. Verify the current APN configuration by sending:
 AT+CGDCONT?
* Look for an entry with an empty APN, which indicates that configuration is required.
2. Configure the APN for Tele2 with the following command:
 AT+CGDCONT=1,"IP","internet.tele2.lt"
3. Confirm the new APN is set by running:
 AT+CGDCONT?
* The response should now display '''internet.tele2.lt''' as the APN.

===Step 4: Restart the Module===

1. Restart the module with the following commands:
 AT+CFUN=4
* Wait for the module to shut down.
 AT+CFUN=1
2. Verify the module has restarted by observing status messages in Putty.

===Step 5: Verify Connection to Operator===
1. Check if the modem has connected to the operator by running this command:
 AT+COPS?
* The response should show the operator’s code (e.g., '''24603''' for Tele2).

===Step 6: Verify Connection to Operator===
1. Open Command Prompt on your computer.
2. Run a ping test to verify connectivity:
 ping google.com
* Successful replies indicate the internet connection is active.

The setup for TRM200 is now complete, and the device should be connected to the internet through the configured APN.
