Set the Ozeki SMS Client app to become your default SMS handler

In order for the Ozeki SMS client app to operate seamlessly it must be set as the default sms handler. This is a very important step. The Android OS puts apps that are not opened by the user regularly into sleep or deep sleep to save battery power. It also often removes the permissions granted to apps when they are put into deep sleep. By setting the Ozeki SMS client as your default SMS handler you can prevent it from being disabled by Android. This is required to be able to provide a reliable sms gateway service for your PC, that is able to operate for months and years without interruption.

By setting the Ozeki SMS Client app as your default SMS handler, you instruct your android phone to forward all incoming sms messages to it, and you allow this app to send sms messages from your phone. This is your desired operation if you want to use your android phone as an SMS gateway. (You an set the SMS functionality back by uninstalling the Ozeki SMS Client from your phone, or by following the instructions in the how to configure the default sms handler in your android device guide).

Grant permissions

After you set the Ozeki SMS Client as your default SMS handler, you may click on the Start button to start the Gateway service. On the first attempt, the app will request various permissions to operate properly. First it will require permission for external storage. External storage is used for storing log files and configuration information. External storage is used in order to make it possible for you do download log files and backup configuration. This is required by most business customers.

Android phones usually operate from a battery. Battery optimization allows android to disable apps to save battery power. In order to provide a reliable SMS gateway functionality your phone should always be connected to the charger. You should also disable battery optimization on the phone for the Ozeki SMS Client app. This will allow the Ozeki app to operate continuously without interruptions.
