One of the newer additions to our list, Automatic Call Forwarding is an app designed for newer phone releases while still maintaining the same functionality users want in their call forwarding apps. Much like Forward My Calls, Automatic Call Forwarding has both manual and automatic modes that allow you to decide when and how to forward your calls based on the current status of your phone.
At first glance, Automatic Call Forwarding might seem a bit more complicated to set up than it truly is. The opening setup screen asks you to input SIM data that you probably don't know, including information like your "Activate" prefix and suffix, and your deactivation number. Don't worry too much about these settings; for most carriers, using the "Default" setting by hitting the Default button next to each of these settings will work fine for your SIM card data.
Once you're past the setup screen, Automatic Call Forwarding allows you to set and use as many WiFi networks as you wish. While you're active on those specified connections, the app will route all of your calls from your primary number to whatever number you add to your settings. You can also activate call forwarding whenever the device itself boots up, or when you've disconnected from a WiFi network. It makes the app a lot more flexible than some of the other apps available on the Play Store, even if it means you have to go through a complicated setup process to get there.
Automatic Call Forwarding catches your calls before they reach your phone by using your SIM data, so if the default settings the app uses don't apply to your specific carrier, you'll have to find the data for your own account by contacting your carrier, or you can try another app on this list. Overall, the default settings worked well in our tests, and the program was efficient in finding calls before they reached the first number.
Of course, as with any application on this list, your millage may vary, so keep in mind that SIM cards and call forwarding are both a bit complicated. The good news: the developer team for this app is still really active, so users won't have to worry about not receiving an update or a response if they're having trouble using the forwarding feature. I found the app to be functional and, in a rare case for this genre of application, good-looking enough to feel like a modern day application. Definitely give this one a try.
