Last Call Forward

Forward your calls when your battery is discharged. Last Call Forward monitors your battery level, and if it drops bellow the defined level, it'll forward your calls to another phone. Ideal for people that constantly forget to charge their phone.

Setting up is pretty straight forward - you need to enter "call forward on" code, and "call forward off" code. You need to obtain these from your carrier, and they generally are constructed like this:

For GSM:
Call forward on code: *21*[phone_number]#
Call forward off code: ##21#

For some North America operators:
Call forward on code: *72[phone_number]
Call forward off code: *73

For Sprint Nextel cellphone company:
Call forward on code: *72[phone number]
Call forward off code: *720

There are various type of call forward codes, but since it's assumed that there is no battery left on your device, you only need the "forward all calls" code. There is a test button next to each field in the application. You can use it to test if the call forward codes are working.

Please email me at lastcallforward@gmail.com if there are any problems, and I'll do my best to fix them.

FAQ

Q: Why does Last Call Forward want permission to DIRECTLY CALL PHONE NUMBERS?
A: Call forwarding is done by dialing a MMI code. The code looks like *21*[phone_number]#, and is dialed like a regular phone number.
