Why is it writen No Service/Limited Service in the Web UI?
There is one reason why, the Limited-Service text is written next to the Network and Web icon. The main reason can be that your SIM card is protected by a PIN code that needs to be entered in the device Web UI to activate the network.
When the No-Service text is written, it can be due to the fact that the SIM card is not inserted properly and is not detected by the device.
But it is also possible
that your SIM card is detected but not automatically recognized by the device.
In this case you must connect to the Web UI and check the APN settings of your
service provider. This procedure is explained in the following section: How do I check and edit the APN settings of my service
provider?
