The APN the device uses can be configured with the following parameters:
$apn – to set up UPN adres
$apnu – to set up user
$apnp – to set up password
The following SMS is an example of how to configure correctly APN settings:
12345,S:$apn:“apnaddress.com”,S:$apnu:“user”,S:$apnp:“password”
Response:
[“OK”,“OK”,“OK”]
This example sets the APN apnaddress.com ($apn) with the user user ($apnu) and the password password ($apnp). These values must be inside quotation marks ( “ ) when setting up APN configuration.
