3G Watchdog app for Android monitors your 4G/3G/Edge/GPRS data usage

I want to set usage for my plan/week/month without changing the day history [Pro version 1.5.0+]

Written by Richard. Posted in FAQs

Prior to version 1.5.0, manually setting the plan/week/month usage would not update the other period totals in order to stay consistent. Since 1.5.0 if you set usage (in the app on the Plan/Week/Month tab, in Menu > set usage) it will evenly (version 1.5.0) or proportionally (pro-rata, version 1.5.1+) distribute this usage amount over the days of the plan/week/month. The periods including these days will be recalculated accordingly.

For example, let’s say your plan started ten days ago, your plan usage is at 20 MB and you want to update your usage to 100 MB (+80 MB). You would set the plan usage to 100 MB. This would also distribute this new value over the ten days so the day history will be changed. If you want to update your usage amount to 100 MB but you want to preserve as much of the day history as possible, instead of setting the plan usage, add 80 MB to today‘s usage (Day > Menu > Set Usage). This way the previous days will not be affected.

What is the “Restrict background data to WiFi” feature? [Pro version]

Written by Richard. Posted in FAQs

The “Restrict background data to WiFi” feature (formerly named “Restrict to WiFi”) allows you to restrict data transfers done by selected applications while they are in the background. It has been introduced in 3GW Pro 1.11.0 and requires Android 2.2+ (Froyo).

To apply it, go to the “usage by application” screen, press on the target application and select “Restrict background data to WiFi” in the menu. To revert to the non restricted state, press on the target application and select “Allow on mobile” in the menu.

The function monitors apps and attempts to terminate their background processes when they start transferring data on mobile networks. Note that:
– Apps will have transferred some data (usually a small amount) before they can be detected and terminated.
– The termination doesn’t require your phone to be rooted, but applies only to background transfers. if you open the app (so it is in the foreground) and it transfers data, it will not be terminated, because it happens while you are here to control what happens, unlike in the case of a background transfer. Android forbids a non privileged application to kill another one, it’s only possible to terminate background processes.
– Some rare applications like Facebook don’t seem to be stoppable. When terminated they obstinately restart again and again. To try to restrict them may actually be counterproductive (more data transfered!) and it is suggested to not attempt to restrict them.

To summarize, the “Restrict background data to WiFi” feature is not a firewall which can totally block an application. It attempts to reduce the background usage of an application, and will usually succeed, except for some applications like Facebook (unfortunately we have no comprehensive list of apps concerned).

SwitchPro widget & Airplane mode

Written by Richard. Posted in FAQs

If you are using the SwitchPro application to toggle the Airplane mode, make sure that the following SwitchPro option for Airplane mode is deactivated/unchecked: “Turn off signal only (Airplane mode will only turn of the mobile network)”. Otherwise there will be problems with the SIM card identification by 3GW when you enter Airplane mode.
