 ### Selecting socket type (TCP or UDP)
 
 
-You can choose which socket type the application should use; however, please note that TCP is a more reliable tranmission protocol. For example:

+### Turning on the tracing and trace level
+
+If you like to add more traces or follow the current ones you can turn traces on by changing `mbed-trace.enable` in mbed_app.json
+
+```"target_overrides": {
+        "*": {
+            "target.features_add": ["LWIP", "COMMON_PAL"],
+            "mbed-trace.enable": false,
+```
+
+After you have defined `mbed-trace.enable: true`, you can set trace levels by changing value in `trace-level`
+
+ ```"trace-level": {
+            "help": "Options are TRACE_LEVEL_ERROR,TRACE_LEVEL_WARN,TRACE_LEVEL_INFO,TRACE_LEVEL_DEBUG",
+            "macro_name": "MBED_TRACE_MAX_LEVEL",
+            "value": "TRACE_LEVEL_INFO"
+        }
+```

 ### Board support
 
 The [generic cellular modem driver](https://github.com/ARMmbed/mbed-os/tree/master/features/netsocket/cellular/generic_modem_driver) this application uses was written using only a standard AT command set. It uses PPP with an Mbed-supported external IP stack. These abilities make the driver essentially generic, or nonvendor specific. However, this particular driver is for onboard-modem types. In other words, the modem exists on the Mbed Enabled target as opposed to plug-in modules (shields). For more details, please see our [Mbed OS cellular documentation](https://os.mbed.com/docs/latest/reference/cellular-api.html).
